G2, formerly known as G2 Crowd, is a Chicago-based peer-to-peer review platform for business software and services, founded in 2012 to provide authentic user insights that help companies discover, evaluate, and manage technology solutions.^[1][2][3] The company was established by a team of five entrepreneurs, including CEO Godard Abel, Tim Handorf, Mike Wheeler, Matt Gorniak, and Mark Myers, who previously worked together at BigMachines and sought to disrupt traditional analyst-driven software evaluations by leveraging real-user reviews.^[3][4] As the world's largest tech marketplace, G2 features over 180,000 products and services across more than 2,100 categories, with millions of validated reviews from users at every Fortune 500 company and beyond.^[1] Headquartered at 100 South Wacker Drive in Chicago, Illinois, G2 has grown to serve over 3,600 global customers, including more than 60% of the Forbes Cloud 100 companies, by offering tools for buyers to compare options, sellers to build visibility, and investors to gauge market trends.^[2][1] The platform has secured $257 million in total funding from prominent investors and emphasizes trust through rigorous review validation processes, while also engaging in philanthropy via initiatives like G2 Gives, which has raised over $1 million for charities.^[1]

Overview

Following its early 2026 acquisition of Capterra, Software Advice, and GetApp from Gartner, G2 further solidified its leadership in the software review and discovery space by incorporating these platforms' vast user bases, verified reviews, and comparison tools, resulting in an even larger marketplace for B2B software evaluation. In 2025, G2 accelerated its global market reach, serving more than 100 million global buyers through g2.com and syndications to marketplaces like AWS and Microsoft Azure. The marketplace expanded to feature over 200,000 products and services, 175,000+ vendors, and 2,000+ categories. G2 surpassed 3 million reviews in 2025. AI-related growth was significant, with 20,000+ AI products listed (+391% year-over-year) and 170,000+ AI reviews (+32% year-over-year). G2 established leadership in answer engine optimization (AEO), becoming the most cited B2B software source across large language models and ranking among the top 20 most cited domains overall per a Semrush study in October 2025. G2 offers vendor tools such as the AI Visibility Dashboard (partnered with Profound for LLM citation tracking and benchmarks), Performance Analytics featuring AI Insights (CRM integration for attribution of G2/AI influence on pipeline) and Churn Threats, plus AEO Traffic insights for measuring AI-driven engagement. These support vendors amid 87% of B2B buyers using AI chatbots for research. Web traffic grew over 20%. Community efforts included the AI in Action Roadshow (sold-out events with expert speakers) and the Reach virtual event featuring speakers from companies like Reddit and Canva. These achievements position G2 as a trusted data source in the AI-driven B2B software ecosystem. G2 has established leadership in answer engine optimization (AEO) by developing tools and features to help vendors optimize visibility in AI-driven search. Key innovations include the AI Visibility Dashboard (launched via partnership with Profound in September 2025), which tracks G2 citations in LLMs and provides benchmarks; and Performance Analytics enhancements in December 2025 adding AI Insights (CRM-linked opportunity influence) and Churn Threats (proactive retention alerts). The AEO category's first Grid Report in Winter 2026 highlighted Profound as definitive leader, reinforcing G2's ecosystem role. ^[5] G2's marketing approach prioritizes customer-led growth through user-generated reviews, strong performance in search engine optimization (SEO) extended to answer engine optimization (AEO), high-quality content via reports and events, and marketplace syndication. Public information indicates no major reliance on traditional influencer marketing or ambassador programs, consistent with its emphasis on authenticity in the B2B software evaluation space. In October 2024, G2 introduced its WhatsApp Marketing Software category to help buyers discover specialized tools for leveraging WhatsApp as a marketing channel, driven by the platform's nearly three billion active users and growing business adoption via the WhatsApp Business API. The category addresses the need for software that enables real-time engagement, personalized campaigns, automation, and performance tracking. G2 highlighted key benefits of WhatsApp marketing, including high engagement rates (98% open rates on messages), personalized one-to-one communication, support for diverse content formats (multimedia, interactive buttons), analytics for delivery/read rates, and cost-effectiveness for global reach. As of early 2026, the category's Grid rankings featured Insider One as the Leader and Easiest to Use, QuickReply.ai as Highest Performer, Wati as Top Trending, and ActiveCampaign as Best Free Software. Other notable tools include respond.io, WebEngage, MoEngage, and CleverTap, with many integrating WhatsApp into broader omnichannel strategies and CRM systems.^[6][7] G2's annual Best Software Awards continued in 2026, with announcements in February recognizing top products based on verified user reviews. Notable placements included Deltek in the Best ERP Software Products list as the #1 Project-Based ERP Provider, highlighting excellence in project-oriented financial and management solutions.

G2's mission is to democratize software, disrupt the traditional analyst model, and build trust by putting the authentic voices of millions of software buyers front and center. When software choices are based on real experiences and sellers act on those insights, everyone can reach their true potential. The company's vision is to become "Where you go for software," fostering a world where B2B software decisions are driven by transparent, peer-reviewed insights rather than traditional analyst reports. G2's culture is centered on the PEAK values:

• Performance: Commitment to building a talented team that delivers high-impact results and thoughtful work.
• Entrepreneurship: Grit, forward-thinking, and innovation to invent new business models and technologies.
• Authenticity: Building a company where employees can be genuine, mirroring the platform's focus on real reviews and people.
• Kindness: Acting with heart, compassion, and purpose, including community support and philanthropy.

These values guide conscious leadership, employee growth, DEI initiatives, and operations, emphasizing support for the "whole self" through benefits, development opportunities, and giving back (e.g., G2 Gives and Pledge 1%).

Platform and Services

G2 functions as a peer-to-peer marketplace for business-to-business (B2B) software and services, enabling users to discover, compare, and select solutions through aggregated authentic peer reviews.^[1] The platform addresses trust gaps in B2B software selection by providing transparent, verified user feedback that powers personalized recommendations and reduces reliance on vendor marketing materials.^[8] With over 3 million verified reviews as of October 2025, G2 empowers millions of software buyers to make data-driven decisions across diverse categories.^[9] Central to G2's operations is its review collection and validation process, which ensures the authenticity and reliability of user-generated content. Reviews are submitted by verified users and undergo a multi-step verification and moderation process, including identity confirmation via LinkedIn profiles, business email addresses, or personal emails accompanied by supporting documentation such as employment screenshots.^[10] This process is the same for both software products and service companies (professional services, agencies, etc.), with no notable differences in core validation steps. Reviews undergo moderation based on G2's Community Guidelines, which prohibit fake or incentivized reviews, and G2 employs an unbiased moderation approach to detect and exclude AI-generated or incentivized content, maintaining that every review reflects genuine user experiences.^[11] For service companies specifically, G2 uses a distinct review form with tailored questions focused on service attributes such as Professionalism, Expertise of Team, Responsiveness, Execution Ability, and Communication Skills. These reviews contribute to Satisfaction scores, weighted by volume, recency, and quality (e.g., thoroughness via Flesch-Kincaid readability).^[12] For buyers, G2 offers comprehensive software discovery tools, including searchable grids, comparison charts, and ratings based on user satisfaction metrics to streamline the evaluation of potential purchases.^[8] Vendors benefit from marketing and lead generation solutions, such as profile optimization, buyer intent data to identify in-market prospects, and content subscriptions that enhance visibility and engagement on the platform.^[13] Investors access G2's data analytics through its Data Solutions, which provide real-time buyer behavioral insights, adoption trends, and market mapping to inform investment strategies and forecast demand in software categories.^[14][15] As of 2025, G2 covers more than 2,100 categories encompassing over 180,000 products and services, making it a comprehensive resource for B2B technology ecosystems.^[1] Notable examples include the Data Warehouse Automation category, introduced in September 2021 to cover tools that automate data warehouse lifecycle processes such as data ingestion, processing, and transformation,^[16] and the Answer Engine Optimization (AEO) category, launched in March 2025, which focuses on tools that optimize brand visibility in AI-generated answers and AI-powered search environments.^[5] Additionally, the eLearning Content Software category provides off-the-shelf content libraries including cloud-based courses, lessons, videos, and more for businesses and professionals, featuring user reviews (updated as of February 2026), comparisons, free options, small business and enterprise picks, and related resources/articles.^[17] Additionally, G2 features a dedicated category for Real Estate Investment Management software, where users can compare and review tools that provide financial and operational insights for asset managers, real estate investors, and stakeholders. G2 publishes rankings, market movers, and buyer intent data for this category based on user reviews and trends.^[18] This extensive coverage, combined with its verified review database, positions G2 as a critical tool for bridging information asymmetries between buyers, vendors, and stakeholders in the software industry.^[8] G2 hosts numerous specialized categories, including Cross-Channel Advertising Software, which covers tools that enable advertising across multiple digital channels such as search, display, mobile, social, and video from a unified platform. Rankings in this and other categories are determined by the proprietary G2 Score, combining user satisfaction from verified reviews and market presence. For example, in the Spring 2026 Report, StackAdapt was ranked #1 in Best Cross-Channel Advertising Software based on user feedback.^[19] G2 has positioned itself centrally in the AEO ecosystem through innovations and partnerships. In September 2025, G2 partnered with Profound to integrate Profound’s AI visibility data into my.G2 dashboards, providing insights into category mentions by LLMs citing G2. In December 2025, G2 enhanced Performance Analytics with AI Insights (linking G2 signals to CRM for tracking influenced opportunities and pre-pipeline engagement) and Churn Threats to drive revenue retention. The inaugural AEO Grid Report in Winter 2026 recognized Profound as Leader, with Otterly.AI and Scrunch AI as High Performers, Semrush, BrightEdge, and Conductor as Contenders, and Quattr, GetCito, and GenRank.io as Niche players. In late March 2026, G2 announced additional innovations during its quarterly Innovation Event titled "Winning with Trust in AEO." These include AEO Traffic insights, new analytics that measure engagement from AI-generated answers and conversational search experiences, enabling companies to understand how AI-driven discovery influences software evaluation. The announcements also featured expanded Buyer Intent signals, providing greater visibility into where teams are actively researching, comparing, or evaluating competing solutions on G2's marketplace. These features, along with AEO traffic and Spend Data geared toward investors via G2's Data Solutions, support organizations in tracking real-time shifts in buyer demand, competitive activity, and market momentum beyond traditional lagging indicators.

Marketing and Vendor Solutions

G2 provides specialized marketing and data solutions for vendors to capitalize on buyer activity and authentic reviews for lead generation, demand creation, and sales acceleration.

Vendor Marketing Features

G2 provides various tools for software vendors to increase visibility and engage buyers. One such feature is G2 Deals, which enables vendors to advertise exclusive software deals, discounts, or promotions to buyers actively researching their product or category on G2. Vendors submit offers through their My.G2 dashboard under the product profile section. G2 promotes these deals on the vendor's product profile, relevant category pages, the dedicated G2 Deals page, and through broader advertising on G2.com and other channels. When a buyer clicks to claim the offer, they are redirected to a custom landing page on the vendor's website to redeem it. This feature is available as part of G2's paid plans (e.g., Professional or higher) and helps vendors stand out from competitors by targeting high-intent buyers. It is distinct from traditional "deal registration" in B2B channel partner programs, where resellers register sales opportunities with vendors for exclusivity, pricing protection, or support to avoid channel conflict. G2 Deals is a demand-generation and promotional marketing tool rather than a partner pipeline management mechanism. For more details, see G2's official documentation.

G2 Content Subscription

The G2 Content Subscription (also referred to as G2 Content) allows software vendors to license official G2-generated content, including Grid Reports, Momentum Reports, Index Reports, comparison pages, performance statistics, badges, and other assets derived from aggregated user reviews. This content serves as trusted third-party validation and social proof. Vendors integrate this licensed material into their marketing strategies—such as website hero sections, email nurture campaigns, paid advertising, sales collateral, and event materials—to boost credibility and conversion rates. Key benefits include increased click-through rates on campaigns, accelerated pipeline velocity through credible customer proof, and strengthened trust in competitive B2B sales processes.

G2 Buyer Intent Data

G2 Buyer Intent is a data product that aggregates high-intent buyer signals from interactions on the G2 platform, helping vendors illuminate the "dark funnel" of anonymous research conducted via review sites before direct engagement. Key signal types include:

• Product profile visits
• Side-by-side product comparisons
• Category and competitor research
• Engagement with licensed content or sponsored assets

These signals are scored to reflect buying stage and overall intent strength, enabling prioritization of prospects closest to purchase decisions. The data integrates with B2B sales and marketing stacks (including CRM systems like Salesforce and marketing automation platforms) to trigger alerts, enrich leads, and personalize outreach. Benefits include early identification of in-market accounts, pipeline acceleration through timely engagement, competitive intelligence via competitor research monitoring, and enhanced trust-building by connecting prospects with relevant G2 customer reviews and proof points.

G2 Market Intelligence

G2 Market Intelligence is an interactive, real-time dashboard launched by G2 in November 2022 as a "live data hub" for vendors. It aggregates and analyzes millions of data points from verified user reviews, buyer behavior, traffic patterns, and intent signals on the G2 platform to deliver actionable insights on products, competitors, and customer preferences.^[20] The dashboard empowers marketing, product, and go-to-market teams to make data-driven decisions without relying on outdated or manual market research. Key tabs and features include:

• Traffic Analytics: Leverages category traffic data and G2 Buyer Intent signals to reveal buyer activity patterns across categories.
• Satisfaction: Analyzes NPS, key experience drivers, and other satisfaction measures for the vendor's product compared to competitors.
• Win/Loss: Highlights churn trends, reasons for switching, and win/loss intelligence in the competitive landscape.
• Pricing and Contracting Insights: Provides visibility into pricing perceptions and contracting trends.

Data updates in real time, allowing users to segment, export charts and underlying reviews, and respond quickly to market shifts such as changes in NPS or switching behavior. It is part of G2's seller solutions (accessible via sell.g2.com) and targets B2B software vendors seeking a competitive edge through voice-of-the-customer insights.

G2 Data Solutions

G2 Data Solutions is the B2B software intelligence division of G2, a leading peer-to-peer software review and marketplace platform. It provides access to authentic, validated user feedback, real-time buyer behavior data, market intelligence, and buyer intent signals derived from millions of annual visitors and reviews on G2.com. It serves investors, private equity firms, venture capitalists, consultants, growth teams, and go-to-market teams by delivering accurate, validated insights for software investment decisions, competitive intelligence, market research, strategy alignment, identifying product momentum, emerging trends, market share, adoption tracking, and demand forecasting. Key statistics include over 10 years of historical user data, more than 2 million authenticated reviews, insights from over 100 million annual software buyers (including 1.6 million+ enterprises), coverage of 145,000+ products across 2,100+ categories, 100,000+ listed software companies, 48 review fields, and 29.2 million+ visitor patterns. Data is delivered through customizable dashboards, API integrations, automated exports to AWS S3 or Snowflake, and other methods, emphasizing 100% validated user feedback without fake or paid reviews. Target users include global investment teams managing $3T+ in assets under management, who use it for due diligence, identifying emerging trends and product momentum, analyzing market share and competitive ecosystems, tracking B2B customer sentiment, adoption patterns, switching behaviors, and deal sourcing ROI. For example, venture firm IVP has cited G2 rankings as a leading indicator of company success. G2 Data Solutions also supports AEO strategies indirectly by providing underlying buyer signals and trends that help vendors optimize their G2 presence for AI discovery, amid shifts where B2B buyers increasingly start research with AI chatbots. For product-led growth (PLG) companies, the flagship offering is G2 Buyer Intent data, which surfaces real-time high-intent prospects engaging with products, categories, or competitors on G2, helping identify in-market accounts, personalize outreach, reduce churn, and integrate with internal product analytics for enhanced growth strategies. Trusted by global investment teams managing over $3T in AUM. Official website: G2 Data Solutions.

Performance Analytics

In December 2025, G2 introduced enhancements to its Performance Analytics suite, including Churn Threats. This feature supports proactive customer retention by detecting when existing customers or accounts begin researching alternative products on the G2 platform. It leverages G2's proprietary buyer behavior data—derived from millions of software evaluations, reviews, and comparisons—to flag real-time competitor research signals, such as views of competitor listings or category comparisons. Churn Threats pushes these alerts directly into CRM systems (e.g., Salesforce) or account-based marketing (ABM) tools, enabling customer success and retention teams to intervene with personalized outreach, win-back campaigns, or targeted engagement before churn occurs. In the context of shifting buyer behaviors—where 87% of B2B buyers use AI chatbots for initial research—Churn Threats provides an early, intent-driven indicator that traditional internal signals (like usage drops) may miss, as it captures anonymous or semi-anonymous evaluation on a trusted third-party marketplace heavily cited in AI-generated answers. Strengths include its timeliness as an early warning system, richness from aggregated buyer intent signals, actionability via integrations, and synergy with G2's AEO tools (like the AI Visibility Dashboard) to strengthen vendor presence and trust. Limitations: Effectiveness depends on vendors having strong G2 profiles and active buyer engagement; it complements rather than replaces broader customer success platforms monitoring internal data (usage, NPS, support); signals may miss evaluations outside G2; and potential for false positives in intent detection. These features build on G2's AI-first innovations, helping software vendors demonstrate value from AI search visibility while mitigating churn risks in subscription-based models.

Partner Program

G2 operates the G2 Partner Program (accessible at partner.g2.com), an Ecosystem-Led Growth (ELG) initiative designed primarily for technology partners, including developers, independent software vendors (ISVs), agencies, and solution experts. The program enables partners to integrate G2's buyer insights, reviews, and data into their tools via APIs, fostering mutual growth through co-marketing, co-selling, shared customer opportunities, and expanded reach to G2's audience of over 100 million annual buyers. Key features include access to a Developer Portal with interactive API documentation, sandbox environments, and support for multiple programming languages to build and scale integrations. Benefits focus on leveraging authentic review data to build trust, turning integrations into revenue streams, and receiving resources for scaling partnerships. Unlike traditional affiliate programs, the G2 Partner Program does not offer performance-based commissions, revenue sharing, or payouts for referrals, leads, or sales driven by external promoters. It emphasizes ecosystem collaboration and indirect revenue growth through integrations and joint opportunities rather than direct affiliate incentives. This aligns with G2's overall marketing strategy, which prioritizes authenticity and user-generated content over influencer or ambassador-style programs.

Key Features and Metrics

G2's platform features the G2 Grid, a proprietary rating system that positions software products and service providers in a quadrant based on two axes: Customer Satisfaction (derived from weighted user reviews, with attributes tailored to the category—for software products, focusing on criteria such as ease of use, quality of support, and ease of setup; for service providers, focusing on attributes such as professionalism, expertise of team, responsiveness, execution ability, and communication skills—weighted by factors including review volume, recency, and quality as assessed by the Flesch-Kincaid reading ease scale) and Market Presence (based on review count, employee count, revenue, web traffic, domain authority, and other metrics). Scores are normalized on a 0-100 scale. This quadrant-style visualization positions products as Leaders, High Performers, Contenders, or Challengers, enabling buyers to quickly identify top options within specific categories. Categories qualify for Grid Reports with at least six products meeting review thresholds. The methodologies were last updated on February 18, 2026, with no major changes announced specifically for 2025 or 2026 beyond ongoing refinements and new category additions.^[12][21] Complementing the Grid, G2 provides buyer intent data, which aggregates signals from user interactions on the platform—such as searches, profile views, and comparison activities—to indicate active research and purchasing interest in particular software solutions.^[13] The platform also incorporates AI-powered search and recommendations through G2.ai, allowing users to query in natural language for personalized software suggestions based on over 3 million verified reviews across more than 2,100 categories.^[9] Additionally, G2 publishes quarterly Market Reports, including Grid and Index editions, that rank products and services using the latest aggregated review data to highlight trends and leaders in evolving markets like AI and cloud computing.^[22] For example, the AEO category experienced over 2,000% growth in listed products since its launch, expanding from 7 to more than 150 solutions, and G2 released its inaugural Grid Report for AEO in the Winter 2026 Reports.^[23][24] G2's quarterly Grid Reports rank products within categories using a proprietary algorithm that combines customer satisfaction (from reviews) and market presence (from share, size, and social data). These reports place products into quadrants: Leaders (high satisfaction and presence), High Performers, Contenders, and Niche. For example, in Contract Lifecycle Management (CLM) and Contract Management categories, 2026 reports highlighted leaders like Conga CLM (#1 in Winter 2026) and LinkSquares (top satisfaction), demonstrating G2's influence in B2B software evaluation. Another example is the Cloud Infrastructure Automation Software category. As of early 2026, GitHub is positioned as the Leader, Railway as the Highest Performer and Easiest to Use, and Nerdio Manager as Top Trending. Other prominent tools include AWS CloudFormation, Red Hat Ansible Automation Platform (with metrics like 8.8/10 for ease of administration and high user satisfaction), and GitLab. Railway has a strong user rating of 4.8/5 stars from 33 reviews. These positions demonstrate crowd-sourced user satisfaction, market presence, and performance in the G2 Grid quadrant.^[25][26] Another example is the Real Estate Investment Management category. G2 maintains a dedicated category for Real Estate Investment Management software, enabling users to compare and review tools that provide financial and operational insights for asset managers, real estate investors, and stakeholders. G2 publishes rankings, market movers, and buyer intent data for this category based on user reviews and trends.^[18] As of October 2025, G2 hosts over 3 million verified reviews, underscoring its scale as the largest repository of peer insights for business technology.^[9] The platform serves more than 3,600 enterprise customers worldwide, including over 60% of the Forbes Cloud 100 companies, demonstrating its influence among top-tier organizations.^[1] G2 maintains a global presence with offices in multiple countries, including its headquarters in Chicago, United_States; European headquarters in London, United Kingdom; an office in Bengaluru, India; and teams in Singapore, as well as remote work opportunities worldwide.^[27] To ensure review authenticity, G2 employs a multi-step validation process that begins with reviewer authentication via LinkedIn profile, verified business email, or a personal email accompanied by a screenshot proving active use of the software.^[10] For software reviews, reviewers must submit an approved screenshot showing themselves logged into the product dashboard to earn the "Verified Current User" label, confirming recent and genuine usage within the past 12 months.^[28] This rigorous approach, combined with AI-assisted moderation to detect inconsistencies or generated content, filters out fraudulent submissions and promotes transparent, unbiased feedback from real users.^[11] Vendors benefit from tools like review amplification programs, which facilitate targeted collection of authentic feedback through integrated prompts and incentives, helping to boost visibility on the G2 Grid and attract buyer intent signals.^[13] Buyers, in turn, access comparison charts that juxtapose up to four products side-by-side, displaying aggregated scores, pros/cons, pricing insights, and review excerpts for informed decision-making.^[29]

Research Methodology

G2's research methodology emphasizes transparency and buyer-first principles in B2B software evaluation. It relies on authentic user reviews, standardized categorization, and a proprietary scoring system to provide data-driven insights.

Review Authenticity and Moderation

G2 ensures review authenticity through a multi-step process:

• Manual moderation by G2's team for every review.
• Verification requiring sign-in with business email, LinkedIn, or Gmail.
• Optional screenshot uploads (not public) for claim support, with validated screenshots labeled.
• Human checks for conflicts of interest; biased reviews (e.g., from resellers) are flagged as "Business Partner" and excluded from scoring.
• Reviews weighted higher if from current/experienced users, non-incentivized, and higher quality (Flesch-Kincaid readability).
• Violative reviews (e.g., incentivized in breach of FTC/G2 guidelines) removed.
• Review decay: higher weight in first 18 months, gradual decline, ~3% weight after ~3 years.

Categorization Methodology

Products and services are categorized by native functionality/features, not intended use or users:

• Inclusion: B2B software/services tied to vendors; hybrid products focus on B2B.
• Exclusion: Pure B2C, duplicate tiers, discontinued (upon confirmation).
• Types: Individual products (single profile, highest-tier features); platforms (multiple categories); add-ons (separate if third-party); services (human-intervention focused, single profile across categories).
• Categories defined with feature requirements; G2's Market Research team evaluates fits, vendors can request changes with evidence.

Scoring and Reporting

G2 uses a proprietary algorithm for the G2 Score (0-100), combining Satisfaction (from review ratings, weighted by volume/recency/quality/source) and Market Presence (review count + external metrics like employee/revenue from ZoomInfo/LinkedIn/Crunchbase, web presence). See G2 Grid for detailed scoring and quadrant visualization. Reports require minimum reviews (e.g., 150 total, 6 products with 10+ each for Grids). This methodology draws from G2's official Research Hub (research.g2.com/methodology) and documentation (documentation.g2.com/docs/research-scoring-methodologies), ensuring consistent, transparent B2B market representation. G2 publishes quarterly Grid Reports and annual Best Software Awards based on aggregated verified user reviews and market data.

Grid Reports and Indexes

G2 Grid Reports position products in categories using a Grid visualization with axes for customer satisfaction and market presence. Additional indexes include the Results Index, which evaluates business outcomes and value delivery. In the Results Index, G2 incorporates user responses to review questions on estimated ROI, defined as the payback period in months. The specific question is: "What is your organization's estimated ROI on {reviewed_product} (payback period in months)?" with options: 6 months or less, 7-12 months, 13-24 months, 24-36 months, 37-48 months, 48+ months, or Never Got Full Payback. Products earning "Best Estimated ROI" badges in category-specific Results Indexes demonstrate the strongest performance based on a combination of short estimated payback periods and fast time to go-live, reflecting high perceived value for money from verified users. These metrics help assess ROI and value for money beyond general satisfaction, with faster payback indicating quicker returns on investment in software tools.

Best Software Awards

G2's annual Best Software Awards (e.g., 2026 edition announced in February) recognize top products and companies based on reviews and market presence. Quarterly Grid Reports complement this with detailed category rankings, including results-oriented badges like Best Estimated ROI, Fastest Implementation, and others highlighting tangible business value.

History

Founding and Early Development

G2 was founded in October 2012 as G2 Labs, Inc., by Godard Abel, Tim Handorf, Matt Gorniak, Mark Myers, and Mike Wheeler, all former employees of BigMachines, a cloud-based configure-price-quote (CPQ) software company.^[30][31] The co-founders, drawing from their experience at BigMachines—which Abel had led as CEO before its acquisition by Oracle in 2013—identified a critical gap in the B2B software market: the absence of authentic, peer-driven reviews to guide purchasing decisions, unlike the abundance of consumer review platforms for everyday products.^[32][33] Their initial vision was to create a "Yelp for enterprise software," aggregating user-generated reviews to empower buyers with transparent insights into business tools.^[34] The concept took shape in Abel's basement in Highland Park, Illinois, where the five entrepreneurs brainstormed the platform's core mechanics, emphasizing real-user feedback to build trust in high-stakes B2B purchases.^[30] A beta version of the review site launched in December 2012, inviting several thousand users to test and contribute early reviews before the full public rollout in 2013.^[35] Bootstrapped with seed investments from the co-founders—including an early contribution from Handorf's father—the team established their first office in a modest, leaky-roofed space in Highland Park to centralize operations near Chicago.^[30] This setup allowed the initial five-person team to focus on curating content and fostering a community of reviewers, directly tackling the challenge of unreliable or vendor-biased information in B2B software evaluation.^[36] By 2014, G2 had raised an additional $2.3 million in seed funding from investors including Chicago Ventures and Hyde Park Ventures, enabling the team to expand and refine the platform's aggregation of peer reviews for business software categories.^[36] This early growth phase solidified the company's commitment to democratizing B2B software discovery through verified user experiences, setting the foundation for its evolution into a comprehensive review ecosystem.^[37]

Rebranding and Expansion

In 2013, the company rebranded from G2 Labs to G2 Crowd to highlight its emphasis on crowd-sourced user reviews for business software, marking a shift toward building a community-driven platform for peer insights.^[38][35] During the mid-2010s, G2 Crowd expanded its offerings by launching tools to support vendors, including enhanced analytics and marketing capabilities that allowed software providers to leverage review data for promotion, with significant developments around 2016 coinciding with the growth of its Grid reports. The platform also broadened beyond software to include services such as consulting, introducing dedicated service reviews in 2018 to provide users with evaluations of professional offerings like IT consulting and implementation partners.^[39][40] Geographic expansion accelerated in the late 2010s, with the opening of a London office in June 2019 to serve the European market and support growing international buyer demand, followed by the establishment of a team in Singapore by 2020 to target Asia-Pacific users. This period saw rapid user growth, culminating in the platform surpassing 1 million authentic reviews by November 2019, reflecting increased engagement from business professionals seeking reliable software recommendations.^[41][34][42] Key partnerships further bolstered the platform's ecosystem, including a 2018 integration with Salesforce that enabled vendors to sync G2 reviews directly into their CRM systems for sales enablement. In 2019, G2 Crowd rebranded to simply G2 to encompass its evolving role as a comprehensive B2B marketplace, a change that aligned with the acquisition of Advocately to enhance review collection and amplification tools for vendors.^[40][43][44]

G2 has raised a total of $258 million in funding across seven rounds between 2013 and 2021.^[45] These investments supported the company's evolution from a nascent review platform to a comprehensive software marketplace, with early capital focused on product development and team growth, and later rounds enabling international expansion and strategic acquisitions.^[46][47] The initial seed round occurred in February 2013, raising $2 million from undisclosed investors to launch the core peer-to-peer review platform for business software.^[48] This was followed by an additional seed investment of $2.3 million in April 2014, led by Chicago Ventures and Hyde Park Venture Partners, along with individual angels, bringing the total seed funding to over $4 million and funding initial platform enhancements and user acquisition efforts.^[36][49] In July 2015, G2 secured $7 million in its first Series A round, led by Pritzker Group Venture Capital, with participation from High Alpha, Chicago Ventures, Hyde Park Angels, TechNexus Venture Collaborative, and 500 Startups.^[50] The funds were allocated to hiring, marketing, and expanding coverage to additional software categories.^[51] An extension to this round came in December 2016 with $4.3 million raised from existing investors, primarily to scale operations and refine the review aggregation algorithms.^[52][48] The Series B round in May 2017 raised $30 million, led by Accel, with contributions from Pritzker Group Venture Capital and the company's founders, Tim Handorf and Mark Myers.^[47][53] This capital accelerated global community building and platform features, aiming to increase headcount from 100 to 350 employees.^[54] G2's Series C funding totaled $55 million in October 2018, led by IVP, alongside Emergence Capital, Accel, and Pritzker Group, pushing cumulative funding to $100 million at the time.^[55][56] The investment supported the transition toward a full marketplace model, including tools for request-for-proposal processes and solution management, while fueling a 500% headcount increase.^[55] The largest round, a Series D, closed in June 2021 with $157 million at a $1.1 billion valuation, led by Permira and including Accel, Emergence Capital, IVP, HubSpot Ventures, Salesforce Ventures, LinkedIn, and individual investors Auren Hoffman and Thomas D. Lehrman via Teamworthy Ventures.^[46] These proceeds were directed toward product innovation, team expansion, and furthering international reach to solidify G2's position as the leading software marketplace.^[46]

Valuation and Use of Funds

In June 2021, G2 achieved unicorn status following its Series D funding round, which valued the company at $1.1 billion post-money.^[46] This milestone reflected the platform's rapid growth as a leading software marketplace, supported by a community of 60 million software buyers and over 2,000 corporate partners at the time.^[46] The $157 million raised in the Series D round was allocated to key strategic areas to accelerate platform scalability and market presence. A significant portion went toward product development, including enhancements to the core G2.com platform and G2 Track, a tool for software spend management adopted by nearly 1,000 enterprises.^[46] Funds also supported global expansion efforts to broaden the international software community, contributing to the establishment of offices in London (UK), Bangalore (India), Singapore, and Dublin (Ireland), in addition to the Chicago headquarters.^[46][57] Approximately one-fifth of the investment focused on marketing solutions to help vendors boost revenue and reputation, while the remainder expanded the team to sustain overall operations.^[46] Subsequent product investments have included AI-powered tools, such as personalized AI agents for buyer-vendor matching, enhancing discovery and decision-making processes.^[58] Since 2021, G2 has not announced new public funding rounds, shifting emphasis to internal profitability and revenue expansion through enterprise subscriptions and vendor services.^[48] By 2024, the company reached $113 million in annual recurring revenue (ARR), with a net revenue retention rate of 130% and over 20,000 paying customers, underscoring sustained financial health amid a competitive B2B software landscape.^[59] These investments have directly bolstered G2's scalability, enabling the platform to serve over 100 million annual software buyers and list more than 180,000 products across 2,100 categories by 2025.^[60] This growth has solidified partnerships with thousands of vendors, including major players like Salesforce and Adobe, facilitating transparent software evaluation and procurement at global scale.^[46][1]

Financials

G2 has raised $258 million in funding and achieved a valuation of $1.1 billion. Estimated annual revenue varies by source, ranging from $80 million to $163 million as of 2024-2026 reports, with employee counts between 1,000 and 1,400 (approximately 1,431 as of early 2026).

Acquisitions

Major Acquisitions

G2 has completed four major acquisitions as of 2026, focusing on enhancing its software review platform through data integration, review collection, and AI-driven research capabilities.^[61] In December 2018, G2 acquired Siftery, a platform that tracked business software usage and tech stacks to help companies optimize spending. The deal aimed to incorporate Siftery's database of over 2,000 software products and usage data from thousands of companies into G2's ecosystem, enriching peer reviews with objective adoption insights.^[62][63] G2's next acquisition occurred in May 2019 with Advocately, a B2B customer advocacy platform designed to facilitate authentic reviews from verified users. This move was intended to accelerate review collection by automating advocacy workflows, thereby increasing the volume and reliability of user-generated content on G2's marketplace.^[44][64] In June 2025, G2 acquired unSurvey, a Y Combinator-backed startup offering an AI-powered system for conducting conversational interviews and market research. The integration sought to enable deeper, more nuanced insights through human-like AI interactions, transforming traditional surveys into dynamic dialogues for software evaluation.^[65][66] In January/February 2026, G2 acquired Capterra, Software Advice, and GetApp from Gartner. This acquisition integrates these established software review and comparison platforms into G2, significantly expanding its database of user reviews, categories, and marketplace reach. The move consolidates G2's position as a leading peer-review platform for business software, combining G2's user-generated review model with the acquired platforms' extensive vendor listings and advisory resources.^[67][68] In a related divestiture, G2 sold its G2 Track SaaS management tool to BetterCloud in March 2024, allowing the company to concentrate resources on its core software review and marketplace operations.^[69]

Strategic Impacts

The acquisition of Advocately enabled G2 to automate customer advocacy processes, reinforcing the platform's reliance on peer-driven trust for software evaluations.^[44] The 2025 acquisition of unSurvey introduced AI-moderated conversational interviews, augmenting G2's research offerings with qualitative insights that enriched the depth of data in its 2025 Market Reports and facilitated more nuanced buyer-seller interactions.^[65] Collectively, these acquisitions shifted G2's focus from traditional reviews toward AI-powered analytics and insights; meanwhile, the divestiture of G2 Track allowed the company to streamline operations and concentrate on its foundational review and marketplace strengths.^[69]

Milestones

Product and User Growth

G2's product evolution and user adoption have progressed steadily since its early years, marked by key milestones in review accumulation and platform enhancements that bolstered its credibility as a trusted resource for business software evaluation. In December 2015, the platform surpassed 50,000 verified user reviews, with over 28,000 added that year alone, demonstrating rapid initial growth and establishing a foundation of authentic user feedback.^[70] By late 2019, G2 achieved a significant benchmark with 1 million unbiased reviews, reflecting accelerated user engagement and the platform's expanding influence in the B2B software discovery space. This milestone coincided with enhancements to the G2 Grid, a comparative rating tool that visualizes vendor performance across satisfaction and market presence quadrants, aiding users in informed decision-making.^[71][72][73] In 2021, G2 attained unicorn status following a $157 million Series D funding round that valued the company at $1.1 billion, enabling further platform scaling and an expansion into reviewing services beyond traditional software categories to address broader business needs, including the introduction of the Data Warehouse Automation category in September 2021, which automates data warehouse lifecycle processes. This period supported ongoing user growth, culminating in the platform reaching over 2 million authentic reviews by early 2023, underscoring sustained adoption amid increasing marketplace complexity.^[74][75][16] By the end of 2023, G2 neared 2.5 million verified reviews, driven by innovations such as the introduction of AI-specific evaluation features in its review form, allowing users to assess capabilities like text generation and summarization in software products. These AI enhancements, including the launch of Monty—an AI-powered business software advisor integrated with ChatGPT—facilitated more nuanced feedback and attracted tech-forward users, contributing to the platform's diversification into AI-driven insights.^[76][77][78] As of May 2025, G2 exceeded 3 million reviews, solidifying its position as the world's largest repository of peer-to-peer software and services feedback. This growth paralleled the addition of over 2,100 categories to the marketplace, including the Answer Engine Optimization (AEO) category launched in March 2025, which focuses on optimizing visibility in AI-generated answers and experienced over 2,000% growth by 2026 (from 7 to over 150 products), as well as specialized ones like AI Agents for HR introduced in September 2025, which enable targeted evaluations of emerging technologies in human resources automation.^{[72][22][79][23][5]}

Market Influence

G2 has significantly shaped the software industry through its annual Best Software Awards, which began in 2013 and recognize top-performing products based on verified user reviews.^[80] The 2025 edition, announced on February 19, highlighted 100 leading software products out of over 13,000 eligible entries, with standout winners including Salesforce Sales Cloud for its excellence in sales automation.^[81] These awards serve as a benchmark for buyers and vendors, influencing product selection and marketing strategies by providing data-driven rankings that emphasize user satisfaction and market performance.^[82] Complementing the annual awards, G2 publishes quarterly reports that analyze emerging trends and buyer behaviors in the software sector. The Spring 2025 reports, released on March 25, and the Fall 2025 editions, issued in September and October, delved into topics such as AI integration in SaaS, revealing how artificial intelligence is accelerating adoption and reshaping vendor competitiveness. Additionally, the Winter 2026 reports, released in December 2025, included the inaugural Grid Report for the Answer Engine Optimization (AEO) category, marking its maturation as a report-ready category reflecting the rise of AI-driven search optimization.^[83][22][24] These reports, drawn from millions of user reviews, guide industry professionals in understanding shifts like the rise of AI agents, which are moving beyond hype to deliver tangible value in productivity tools.^[84] G2's partnerships with over 2,000 vendors, including major players like HubSpot and Adobe, facilitate co-marketing initiatives and data-sharing for enhanced visibility and trust-building.^[46] These collaborations enable vendors to leverage G2's platform for authentic review collection and promotional badges, while G2's aggregated data supports investor due diligence in evaluating software investments.^[85] The company's influence extends through key research outputs, such as the 2024 Buyer Behavior Report, which demonstrated AI's profound impact on B2B spending, with 56% of buyers reporting recent AI platform purchases and 57% expecting ROI within three months.^[86] G2's data is integral to industry benchmarks, with over 60% of the Forbes Cloud 100 companies utilizing the platform, underscoring its role in informing high-stakes decisions like cloud vendor selections.^[1] G2's Buyer Behavior Report is an annual research publication examining trends in B2B software buying, including buyer plans, behaviors, attitudes, spending expectations, ROI demands, trust factors, security considerations, service needs, and the role of AI in the purchasing journey. It combines large-scale surveys of B2B decision-makers with proprietary G2 platform data (user interactions, reviews, searches) for validated insights serving vendors and go-to-market teams. Core methodology features online quantitative surveys targeting global B2B decision-makers (individual contributors to C-level), primarily in North America, EMEA, and APAC, fielded in March or April, enriched with platform behavioral data. Recent editions, notably 2025, leveraged generative AI for focus area definition, survey optimization, result analysis, and insight/visualization generation.

Recent Developments

On December 16, 2025, G2 announced enhancements to its Performance Analytics dashboards, introducing AI Insights and Churn Threats. AI Insights connects G2 data to a company's CRM platform to identify opportunities influenced by G2 activity, accounts that engaged on G2 before entering the pipeline, and key metrics such as close rate, deal size, and sales cycle length. These features build on the AI Visibility Dashboard (in partnership with Profound) to help software vendors measure and optimize their answer engine optimization (AEO) presence, turning visibility in AI search into measurable pipeline and revenue impact while aiding revenue retention through churn prediction. In March 2026, G2 announced several innovations to support software vendors in the AI answer economy, emphasizing trust and real-time insights. Key additions include:

• AEO Traffic insights: New analytics measuring engagement from AI-generated answers and conversational search, offering visibility into how AI channels influence software discovery and evaluation.
• Model Context Protocol (MCP): An architecture enabling AI assistants (initially integrated with Claude from Anthropic) to directly access verified G2 data such as buyer reviews, research behavior, and competitive insights for more accurate responses.
• Expanded G2 Intelligence features: Including Competitive Pulse (combining CRM, buyer intent, and research to identify deal risks and churn threats), enhanced Buyer Intent signals, and spend/contract intelligence from over $100 billion in SaaS agreements.

Additional enhancements: Structured category FAQs, guided discussion prompts for reviews, focused feature lists to improve AI parsability, and further review verification via LinkedIn integration (verifying over 100,000 reviews, reducing rejections by 40%). These build on the December 2025 Performance Analytics updates (AI Insights and Churn Threats) and the Profound partnership, reinforcing G2's role as a trust layer in AI-driven software decisions.

Global Hiring Services Category

In September 2024, G2 introduced the Global Hiring Services category to assist businesses in navigating international talent acquisition amid a growing skills gap, where 25% of job skills have changed since 2015. The category enables comparison of providers offering legal arrangements such as Employer of Record (EOR), where the provider acts as the legal employer handling compliance and payroll; Professional Employer Organization (PEO), a co-employment model; and Agent of Record (AOR), focused on contractors. Additional services may include HR consulting, immigration support, and benefits administration. This helps companies hire globally without establishing local entities, reducing risks and administrative burdens, particularly for small and mid-market firms.

Answer Engine Optimization (AEO) Initiatives

G2 has positioned itself as a leader in answer engine optimization (AEO) by developing tools that help software vendors measure and enhance their visibility in AI search. In September 2025, G2 partnered with Profound to power the AI Visibility Dashboard (generally available), which ingests Profound's AEO data to show how often G2 product and category pages are cited in LLMs, benchmark competitive standing, and identify top-performing prompts. On December 16, 2025, G2 expanded Performance Analytics with AI Insights and Churn Threats. AI Insights connects G2 to CRM platforms to reveal G2-influenced opportunities, pre-pipeline engagement, and key metrics (close rate, deal size, sales cycle). Churn Threats identifies at-risk customers researching competitors on G2, pushing alerts to ABM/CRM for win-back campaigns. These features build on G2's AI-first innovations to turn AI search visibility into measurable pipeline and retention impact, reinforcing G2's role as a trusted source in AI-driven B2B software discovery.

AI Integration and Review Moderation

G2 has embraced generative AI to enhance review collection and accessibility while upholding authenticity. In 2025, G2 reported over 170,000 AI-assisted reviews, a 32% year-over-year increase, including conversational AI tools that enable natural, detailed submissions (often 3-10x more content than traditional forms). G2's policies permit AI-assisted reviews (e.g., for grammar, readability, or drafting) from verified users (via Vendor Verified, LinkedIn Verified, or in-app), but reject majority AI-generated content from unverified sources. AI-detection and moderation tools filter spam, fraud, and inauthentic submissions. G2 leads in answer engine optimization (AEO), ranking as the most cited B2B software source in large language models per 2025 studies, ensuring strong visibility in AI-driven discovery despite organic traffic shifts. The early 2026 acquisition of Capterra, Software Advice, and GetApp from Gartner further strengthened this position by consolidating vast verified review data, amplifying G2's role as a foundational source for AI-synthesized recommendations in B2B software evaluation.

AI and Security Categories

As of March 2026, G2's AI Security Solutions category features 36 products. This category focuses on tools that help organizations protect AI assets, including machine learning (ML) models, large language models (LLMs), and AI agents, from misuse and threats. Leading products in the category include:

• Wiz (recognized as the best free option)
• Securiti by Veeam (4.7/5 rating from 83 reviews)
• Microsoft Defender for Cloud
• Zscaler
• Hunto AI

User feedback highlights key pros such as strong monitoring capabilities, automation features, and effective threat detection. Common cons mentioned include the complexity of setup and a notable learning curve for users. This category demonstrates G2's ongoing commitment to covering emerging AI-driven security solutions, providing verified reviews and comparisons to support B2B buyers in the rapidly evolving AI ecosystem.
