Key Information
History
[edit]Origins
[edit]CoStar Group was founded in 1987 by Andrew C. Florance in Washington, D.C., as one of the first companies that digitized and aggregated property data before the Internet became widely available. In 1998, the company went public via an initial public offering on Nasdaq, raising $22.5 million.[3] In June 2004, the lawsuit CoStar Group, Inc. v. LoopNet, Inc. became a landmark case in copyright law about the role of an Internet service provider in monitoring copyrighted content posted on its servers.[4] In October 2009, the company acquired a building from the Mortgage Bankers Association for $41.3 million, which served as the company's headquarters. The building had sold for $97 million two years earlier, with CoStar Group claiming that it had used its analytics data to determine the right time to buy.[5] In 2025, CoStar Group moved its headquarters to Arlington, Virginia.[6][7]
Growth and expansion
[edit]Throughout the 2010s, CoStar Group expanded its footprint in the commercial property industry with a series of acquisitions in North America and Europe. In 2009, it acquired Property and Portfolio Research company Grecam, joining the company's existing Grecam service.[8] In 2012, it acquired the online marketing site LoopNet for $860 million.[9][10] With the acquisition, CoStar Group also took over the Loopnet properties BizBuySell and LandsofAmerica.[11] Two years later, the company acquired Apartments.com for $585 million,[12] as well as Apartment Finder the following year.[13]
From 2017 through 2020, the company acquired the online marketplaces Westside Rentals,[14] ForRent.com (previously owned by Dominion Enterprises),[15] Cozy Services,[16] Off Campus Partners,[17] and Ten-X;[18][19] in addition to the hotel research and analytics firm STR,[3] the residential mobile application provider Homesnap.[20] In April 2021, it acquired Homes.com, a prominent residential real-estate website, from Dominion Enterprises for $156 million in cash.[21] In February 2025, CoStar acquired the 3D spatial mapping company Matterport for $1.6 billion.[22][23]
Overseas, its European division acquired the German real-estate business data company Thomas Daily and the Spanish online marketplace and information provider Belbex in 2016.[24][25] From 2018 through 2023, it acquired the British online marketplace Realla,[26] the German real-estate data company Emporis,[27] the French online marketplace BureauxLocaux,[28] and the British property portal OnTheMarket.[29] After initially taking a 16.9% stake in Australian real estate information company Domain Group, CoStar entered an agreement to acquire 100% of the company for US$1.92 billion in May 2025.[30]
Other activities
[edit]In 2019, CoStar Group announced that Oxford Economics would provide the economic data and forecasts used in its products.[31] The company came under fire in 2022 when Business Insider reported that over 29 current and former employees claimed to have been excessively monitored and micromanaged, including with unscheduled check-in video calls made by the company's IT department, as well as being publicly berated and arbitrarily fired in some cases.[32][33] The company made efforts to take down criticism of itself on various social media platforms. CoStar Group denied the allegations, contending that the discontent had stemmed from the company's high expectations.[32] In 2024, CoStar Group purchased an estimated $35 million worth of airtime at Super Bowl LVIII for four Super Bowl commercials advertising its subsidiaries Homes.com and Apartments.com, which The New York Times described as an effort to rival competitor services such as Zillow and Realtor.com.[34]
CoStar has been criticized for anticompetitive and monopolistic business practices, often using aggressive litigation and "public-relations warfare" to "push [competitors] to the brink of collapse or weaken them enough to make them soft targets for an acquisition".[35] In February 2024, a proposed consumer class action lawsuit was filed against CoStar in multiple states, accusing the company of a price-fixing conspiracy in which it conspired with a group of luxury hotel chains—including Hilton, Hyatt, Marriott, InterContinental, Loews, and Accor—to keep room rental prices artificially high by sharing competitively sensitive information through the company's STR reports. These allegations were based in part on insider information shared by an STR software engineer.[36]

History
Founding and Early Development
CoStar Group was founded in 1986 by Andrew C. Florance, a senior economics major at Princeton University, who initiated the venture from his college dorm room using early personal computing resources to compile and organize commercial real estate data.[9][10] Initially operating under the name Infonet—a predecessor entity focused on real estate public records publishing—Florance drew from his family's background in architecture and real estate, led by his father, Coke Florance, to address inefficiencies in property information access during a period of market turbulence including the late 1980s commercial real estate crash.[10][11] The company's core innovation lay in creating structured databases of building characteristics, lease comparables, and sales data, positioning it as the first independent research organization dedicated to commercial real estate information services.[12] In its formative years through the early 1990s, CoStar Group—incorporated as a Delaware corporation in 1987—prioritized manual data collection and verification by researchers, amassing proprietary datasets on properties, tenants, and transactions primarily in the Washington, D.C., metropolitan area before expanding coverage.[13] Florance served as president of the Infonet phase from 1985 to 1987, transitioning to a formalized structure under Realty Information Group, which emphasized subscription-based access to analytics for brokers, owners, and investors seeking empirical market intelligence over fragmented, anecdotal sources.[14] This approach, grounded in exhaustive on-site inspections and public records aggregation, differentiated CoStar from traditional brokers' informal networks, enabling users to perform causal analyses of rental rates, vacancy trends, and cap rates tied to verifiable property fundamentals.[11] By 1991, the flagship CoStar software product was introduced, delivering PC-based tools for querying and mapping real estate data, which accelerated adoption among professionals despite initial resistance to digitized formats in an analog-dominated industry.[15] Early growth was methodical, with revenue derived from high-margin subscriptions and research services, fostering a research-intensive culture that employed teams to update databases in real time and mitigate biases from self-reported industry data.[16] The entity's evolution to Realty Information Group, L.P., and eventual public listing preparations underscored Florance's vision of scaling empirical data infrastructure, laying groundwork for national expansion amid recovering markets in the mid-1990s.[11][17]Expansion Through Data and Technology
CoStar Group's expansion was driven by the development of a proprietary database that aggregated detailed commercial real estate data, starting with office buildings in Washington, D.C., in 1987 and extending to multifamily, retail, and industrial properties as coverage grew. By the early 1990s, the company employed field researchers to collect and verify lease comparables, sales transactions, and building characteristics directly from brokers, owners, and public records, enabling scalable data accumulation that supported entry into new markets such as Baltimore in 1992 and New York in 1994. This methodical approach to data sourcing created a competitive moat, as the database's depth—encompassing over 6 million properties by the mid-2000s—facilitated analytics services that attracted subscribers beyond initial local boundaries.[10][11] The shift to digital delivery accelerated growth, with CoStar becoming fully web-based in 2000, allowing remote access to its CoStar Suite platform and replacing disk-based distribution with subscription models tied to online marketplaces. This technological pivot coincided with investments in software for data integration and visualization, including upgrades to international services like FOCUS in the UK by 2004, which incorporated local transaction data to mirror U.S. coverage. By systematizing data workflows, CoStar reduced collection costs while expanding to over 90 U.S. markets and select European cities, generating revenue from information services that scaled with database completeness.[11] In the 2010s and beyond, CoStar intensified focus on advanced analytics and automation, migrating infrastructure to cloud-native architectures like AWS serverless in 2019 to handle petabyte-scale data processing and cut compute expenses by 90%. The company began incorporating machine learning for data cleansing and predictive modeling, exemplified by AI enhancements in property valuation and market forecasting tools. In 2023, CoStar invested more than $200 million in technology R&D to refine collection methods and analytics, bolstering platforms like STR for hospitality data. This culminated in the February 2025 acquisition of Matterport for $1.6 billion, integrating 3D digital twin capture with AI and computer vision to automate property documentation and enable immersive virtual tours, thereby expanding data granularity for residential and commercial listings.[18][19][20]Key Acquisitions and Market Diversification
CoStar Group's expansion beyond its core commercial real estate analytics involved strategic acquisitions of complementary platforms and data providers, enabling entry into residential marketplaces, hospitality benchmarking, agricultural land intelligence, international markets, and advanced proptech tools. These moves diversified revenue streams from subscription-based information services to advertising-driven online portals and specialized analytics, reducing reliance on cyclical commercial leasing data. By acquiring established players in fragmented sectors, CoStar integrated proprietary datasets and user bases, enhancing network effects and cross-selling opportunities across property types and geographies.[21][22] A pivotal early acquisition was LoopNet in April 2012 for $860 million, which merged CoStar's research depth with LoopNet's commercial property listing capabilities, creating a dominant online marketplace for brokers and owners. This broadened market access to advertising and transaction facilitation, contributing over $100 million in annual revenue shortly after integration. Subsequent purchases like STR in September 2019 for $450 million introduced hospitality performance data from 75,000 properties worldwide, allowing CoStar to benchmark hotel occupancy, revenue per available room, and market share—metrics previously siloed in the lodging sector.[13][23] In residential real estate, CoStar targeted multifamily and single-family segments through acquisitions such as Apartments.com in 2014 and Homes.com in April 2021 for $156 million, combining listing traffic with Homesnap's mobile tools to challenge incumbents like Zillow. These expanded user engagement via portals handling millions of monthly searches, diversifying into tenant screening via the 2021 Cozy acquisition and fostering agent-centric advertising models. Further proptech integration came with Matterport in April 2024 (completed March 2025) for $1.6 billion, incorporating 3D digital twins and AI-driven spatial analytics applicable to residential, commercial, and hospitality listings, enhancing virtual tours and property valuation accuracy.[21][22] Recent deals underscore geographic and sectoral broadening: Visual Lease in October 2024 added lease administration software for corporate portfolios, streamlining accounting and compliance; Ag-Analytics in February 2025 brought farmland valuation data on 2.8 million U.S. parcels to Land.com, tapping agricultural investment analytics; and Domain Holdings Australia in August 2025 for $1.92 billion established a foothold in Australia's residential and commercial portals, leveraging Domain's agent network for pro-broker innovation amid a $3 trillion property market. These acquisitions, often targeting second- or third-place competitors, have accelerated data aggregation and platform investments, with international revenue projected to grow via Domain's integration.[24][25][26]Business Model and Operations
Core Data Analytics and Information Services
CoStar Group's core data analytics and information services primarily revolve around the CoStar platform, which maintains the industry's most comprehensive database of commercial real estate (CRE) information, analytics, and news. This database encompasses detailed records on over 7 million commercial properties worldwide, including ownership, tenancy, building characteristics, and historical transaction data, supplemented by more than 20 million lease and sale comparables and over 8.3 million additional data points.[5] The platform's data is compiled through a census-level research methodology, leveraging the largest independent research organization in CRE to aggregate information from public records, proprietary surveys, and partnerships with entities such as HM Land Registry and government databases, ensuring broad and verifiable coverage across major markets.[27][28] Central to these services are advanced market analytics tools that deliver granular insights into property performance, submarket trends, vacancy rates, rental and sale price indices, absorption rates, and supply pipelines for asset classes including office, industrial, retail, and multifamily properties.[29] These analytics enable users—such as investors, appraisers, brokers, and lenders—to conduct financial modeling, comparable sales analysis, and forecasting for investment underwriting and portfolio optimization, with real-time updates on availabilities, developments, and competitive benchmarks.[28] The platform's integration of historical trends, key performance indicators (KPIs), and customizable reports supports evidence-based decision-making, distinguishing it from less exhaustive competitors through its scale and timeliness.[5] Specialized extensions, such as CoStar Risk Analytics, build on the core database by incorporating proprietary credit default models like COMPASS to assess CRE loan risks, providing around-the-clock access to property-level valuations, market stress testing, and portfolio analytics for financial institutions.[30] Overall, these services cater to more than 240,000 subscribers globally, combining raw data delivery with interpretive software applications to facilitate precise market navigation and reduce informational asymmetries in CRE transactions.[5] CoStar's emphasis on empirical data aggregation and algorithmic processing underscores its utility in high-stakes environments, where users rely on verifiable metrics over anecdotal estimates.[28]Online Marketplaces and Platforms
CoStar Group's online marketplaces enable commercial and residential real estate transactions by providing platforms for property listings, searches, and auctions, integrating with the company's proprietary data to enhance user decision-making.[1] These platforms collectively serve millions of users, including brokers, investors, tenants, and buyers, facilitating sales, leases, and rentals across various property types.[4] LoopNet operates as the premier online marketplace for commercial real estate, allowing users to list and search properties available for sale or lease in sectors such as office, industrial, retail, and multifamily.[31] It connects tenants, investors, and brokers, with key decision-makers viewing more than 1 million detailed property listings monthly, supported by tools for market analysis and transaction execution.[31] Listings on LoopNet, alongside sister sites like CityFeet and Showcase, feed into CoStar's broader analytics suite, enabling aggregated visibility for auctions via the Ten-X platform.[32] In the residential sector, Apartments.com functions as a leading rental marketplace, offering searchable listings for apartments and other multifamily units, with features for virtual tours and application processing to streamline tenant-landlord interactions.[33] Complementing this, Homes.com targets home buyers and renters with advanced search capabilities, including a "Smart Search" feature launched on October 14, 2025, that processes natural language queries for properties matching spoken preferences.[34] These platforms leverage CoStar's data for accurate pricing, neighborhood insights, and market trends, driving user engagement and transaction volume.[4] Additional specialized marketplaces include BizBuySell, which focuses on business-for-sale listings for entrepreneurs and investors seeking commercial enterprises, and Land.com, dedicated to rural and undeveloped land transactions.[35] Ten-X provides an online auction exchange for real estate and related assets, hosting competitive bidding events to expedite sales and capitalize on market dynamics.[32] Internationally, Domain serves as a property marketplace in Australia, connecting users to residential and commercial opportunities through digital listings and services.[4] These platforms collectively generate revenue through listing fees, premium subscriptions, and advertising, while reinforcing CoStar's dominance in digital real estate intermediation.[1]Data Sourcing and Technological Innovations
CoStar Group employs over 1,500 researchers, forming the largest dedicated research department in the commercial real estate industry, to conduct census-level data collection across properties, transactions, and market metrics.[36] This team utilizes a multi-faceted process involving field verification, broker interviews, analysis of public records and sales documents, and estimation techniques for comparable properties where direct data is unavailable, ensuring comprehensive coverage of the U.S. commercial real estate market.[37] The company has invested more than $5 billion over 38 years in developing and maintaining this proprietary database, which integrates automated and manual quality control mechanisms to validate data integrity and minimize errors.[2] Technological innovations at CoStar Group center on AI integration and advanced visualization tools to enhance data accessibility and analytics. In 2025, the company deployed Microsoft Azure AI Foundry with GPT-4o models to power conversational AI search on Homes.com, allowing users to query properties via natural language (e.g., specifying features like backyard size relative to urban proximity), which processes high-volume queries with low latency using models like Mistral 3B for initial filtering before deeper analysis.[38] This shift from traditional filter-based searches leverages CoStar's vast proprietary dataset to deliver personalized insights, supporting scalability for over 100 million monthly visitors and facilitating global expansion.[38] A pivotal advancement occurred with the February 28, 2025, acquisition of Matterport, which brought 3D digital twin technology capable of digitizing over 50 billion square feet across 14 million spaces in 177 countries.[20] Matterport's platform enables immersive, scalable virtual property tours and AI-enhanced analytics, combining computer vision and machine learning with CoStar's core data to automate measurements, detect anomalies, and generate predictive insights for leasing, valuation, and operations.[20] These tools aim to digitize the $327 trillion global property sector, reducing reliance on physical inspections and improving decision-making efficiency through real-time, data-rich representations.[20]Leadership and Governance
Andrew Florance's Role and Strategy
Andrew Florance founded CoStar Group in 1986 as a senior at Princeton University, initially aiming to digitize commercial real estate information that had previously relied on manual processes and paper-based listings.[39] As the company's Chief Executive Officer and Chairman since inception, Florance has directed its evolution from a startup into a global provider of real estate data, analytics, and online marketplaces, overseeing operations that serve over 7,000 employees and generate annual revenues exceeding $3 billion as of 2025.[9] [40] Florance's core strategy emphasizes building the most comprehensive and accurate real estate database through proprietary data collection, leveraging boots-on-the-ground research combined with technological aggregation to cover commercial, residential, and hospitality sectors across multiple countries.[41] This approach prioritizes empirical data depth over superficial listings, enabling analytics tools that inform leasing, sales, and investment decisions for clients including Fortune 500 firms.[42] Under his leadership, CoStar has invested heavily in vertical integration, developing platforms like CoStar Suite for analytics and marketplaces such as LoopNet for commercial properties, which facilitate direct transactions and reduce reliance on brokers.[9] To accelerate market dominance, Florance has pursued aggressive acquisitions, including LoopNet in 2012 for $860 million to bolster online commercial listings, Apartments.com in 2014 to enter multifamily rentals, and Homes.com in 2021 to challenge residential portals like Zillow.[42] More recent moves encompass STR for hospitality analytics in 2019, Ten-X for auction technology, and an announced intent to acquire Matterport in 2025 for 3D digital twins, enhancing property visualization capabilities.[43] [44] These deals, totaling billions in value, have diversified revenue streams and expanded geographic reach into Europe and beyond, with Q2 2025 revenues reaching $781 million, up 15% year-over-year.[45] Florance's forward-looking tactics include substantial R&D in artificial intelligence and machine learning to automate data verification and predictive modeling, positioning CoStar to capitalize on real estate's shift toward tech-driven efficiencies.[46] He has advocated for disrupting legacy models, as evidenced by Homes.com's rapid subscriber growth to over 100,000 agents by 2025 through targeted marketing and superior data integration, contrasting with competitors' ad-heavy approaches.[47] This strategy reflects a commitment to long-term scalability, with consecutive quarters of double-digit growth attributed to workforce expansion and tech investments rather than short-term profitability trades.[48]Executive Team and Decision-Making Processes
The executive team at CoStar Group is headed by Andrew C. Florance, the company's founder, President, Chief Executive Officer, and Director, a role he has maintained since establishing the firm in 1987.[9] [49] Florance oversees strategic direction, including major initiatives like headquarters relocation to Arlington, Virginia, and campus expansions in Richmond, with the latter project targeted for completion by May 2026.[45] Key supporting executives include Frank Simuro as Chief Technology Officer, responsible for technological infrastructure and innovation; Lisa Ruggles as Senior Vice President of Global Operations, managing international expansion and operational efficiency; Michael Desmarais in a senior financial role; and others such as Gene Boxer, Fred G. Saint, and Jason Butler handling specialized functions in sales, analytics, and business development.[3] [50] The Board of Directors, independent except for Florance per NASDAQ standards, provides governance oversight, with Louise S. Sams appointed as Chairman in April 2025 following a board refreshment that added independent directors John Berisford, Rachel Glaser, and Christine McCarthy.[51] [52] This restructuring established a Capital Allocation Committee, comprising Berisford, McCarthy, OptumInsight CEO Robert Musslewhite, and Florance as chair, to evaluate investments, mergers, and capital deployment decisions.[53] Decision-making processes emphasize empirical data and analytics, aligned with CoStar's core competency in real estate information services, where internal strategies mirror client-facing tools for market assessment and forecasting.[54] Florance drives high-level choices, such as early post-COVID office return policies credited with boosting productivity and the aggressive scaling of platforms like Homes.com through innovation and litigation against competitors.[55] [56] Board-level processes involve the Nominating and Corporate Governance Committee in director selection and succession planning, while full board reviews cover strategy, financial reporting, risk management, and performance metrics without fixed quotas for diversity or other non-merit factors.[57] [58] Capital decisions prioritize long-term shareholder value, as evidenced by ongoing AI investments and European expansion under leaders like Alexa-Maria Rathbone Barker, appointed Head of CoStar Europe in July 2025.[59] [46]Corporate Culture and Employee Dynamics
CoStar Group's corporate culture emphasizes rigorous performance standards, data-driven decision-making, and aggressive growth pursuits, often resulting in a high-pressure environment for employees. Founded by CEO Andrew Florance, the company fosters an intense atmosphere where long hours and metric-based evaluations are commonplace, with management practices including close monitoring of productivity and public accountability for shortfalls.[60][61] Florance has publicly defended this approach as essential for maintaining competitive edge in real estate data services, stating in 2022 that the firm's success stems from a "hard-driving work culture" amid financial reporting.[62] Employee dynamics reflect this demanding ethos, with reports of micromanagement from leadership and a focus on quantifiable outputs leading to elevated stress levels. Aggregate reviews from platforms indicate dissatisfaction, with Glassdoor rating overall culture at 2.6 out of 5 based on thousands of submissions as of 2025, citing excessive workload, constant deadlines, and top-down control as prevalent issues.[63] Similarly, Indeed reviews average 2.8 out of 5, with employees describing the workplace as "toxic and demoralizing" due to unsupportive policies and high expectations that prioritize results over work-life balance.[64] Turnover has historically been significant; in 2021, approximately 37% of U.S. employees departed, attributed by insiders to pandemic-era remote work tensions and perceived bullying in group settings.[65] Despite these challenges, CoStar reports improvements in retention, claiming a 99% rate in 2024 alongside hiring 1,570 new staff and a median tenure of 4.4 years, factors contributing to its recognition as one of Forbes' America's Best Large Employers in 2025.[66] Compensation remains a draw, with entry-level roles offering above-market pay and opportunities for rapid advancement in sales and data roles, though critics among former employees argue that financial incentives fail to offset the emotional toll of the environment.[67] Dynamics vary by department, with sales teams sometimes faring better due to commission structures, but overall, the culture's emphasis on accountability has drawn allegations of fostering fear, including claims of surveillance and demeaning public critiques under Florance's direction.[60][68]Financial Performance
Revenue Sources and Growth Metrics
CoStar Group's primary revenue sources consist of subscription fees for access to its proprietary real estate data, analytics platforms, and online marketplaces, which comprised approximately 96% of total revenues in early 2025. The CoStar Suite, offering comprehensive commercial real estate information and analytics, represents a core subscription product, generating $270.9 million in the second quarter of 2025. Multifamily rental marketplace Apartments.com contributed $292.3 million in the same period, driven by subscription and lead-generation services for property managers and advertisers. Emerging residential platform Homes.com added $28.4 million, reflecting rapid expansion through agent subscriptions and traffic monetization. Commercial listings on LoopNet yielded $75.7 million, primarily from paid listings and premium features.[69][70] Revenue growth has been consistent and accelerating, with full-year 2024 totals reaching $2.74 billion, an 11% year-over-year increase from 2023, supported by expansions in residential and analytics segments. In the first quarter of 2025, revenue rose to $732 million, up 12% year-over-year, marking the 56th consecutive quarter of double-digit growth. The second quarter accelerated further to $781 million, a 15% increase, fueled by record net new bookings of $93 million and a 56% quarter-over-quarter rise in Homes.com paid members. Full-year 2025 guidance projects $3.135 billion to $3.155 billion, implying approximately 15% growth at the midpoint, with third-quarter expectations of $800 million to $805 million (16% year-over-year). This outlook reflects CoStar Group's dominant position in real estate data and technology, positioning it for exceptional growth in recovering property markets, with analysts implying a long-term revenue growth runway of around 15% annually, supported by company guidance for approximately 15% compound annual growth through 2028 and an addressable market exceeding $100 billion.[71][2][69][72]| Fiscal Period | Revenue ($ millions) | Year-over-Year Growth (%) |
|---|---|---|
| Full Year 2024 | 2,740 | 11 |
| Q1 2025 | 732 | 12 |
| Q2 2025 | 781 | 15 |

Profitability, EBITDA, and Cost Structures
CoStar Group's profitability has fluctuated in recent years, reflecting heavy investments in sales, marketing, and platform expansion amid revenue growth. For the full year 2024, net income stood at $138.7 million on revenue of $2.736 billion, yielding a net profit margin of 5.1%, a decline from 15.3% in 2023 when net income was $374.7 million on $2.455 billion in revenue.[36] This compression stemmed primarily from elevated operating expenses outpacing revenue gains, including increased personnel and marketing costs tied to residential marketplace initiatives like Homes.com. In Q1 2025, the company reported a net loss of $15 million on $732 million in revenue, influenced by $31 million in Matterport acquisition-related impacts, while Q2 2025 net income rebounded to $6.2 million on $781.3 million in revenue, though margins remained thin at under 1%.[74][75] Overall, profitability pressures arise from a high fixed-cost base in data operations and sales infrastructure, partially offset by an 80% gross margin driven by scalable subscription revenues.[36] EBITDA metrics, particularly adjusted EBITDA, provide a clearer view of operational cash generation excluding non-cash and one-time items like stock-based compensation and acquisition costs. Reported EBITDA for 2024 was approximately $151.6 million, calculated as operating income plus depreciation and amortization.[36] Adjusted EBITDA showed stronger improvement, with Q1 2025 at $66 million (up 429% year-over-year) and Q2 2025 at $85 million (up 108% year-over-year), reflecting efficiencies in core commercial segments despite residential investments.[74][76] These figures exclude adjustments such as $51.8 million in stock-based compensation in Q2 2025, underscoring EBITDA's role as a preferred internal measure for segment performance over net income, which is more volatile due to amortization of acquired intangibles.[75] For full-year 2024, adjusted EBITDA increased significantly year-over-year, supporting ongoing investments without eroding core earnings power.[77] Cost structures are characterized by high variable and semi-fixed expenses in personnel and marketing, comprising the bulk of operating costs. In 2024, total operating expenses reached about $2.59 billion, with personnel costs at $1.199 billion (44% of revenue), distributed across categories.[36] Selling and marketing expenses dominated at $1.364 billion (50% of revenue), funding a large sales force and advertising for platforms like Apartments.com and Homes.com.[36] Software development (R&D equivalent) was $325.3 million (12% of revenue), focused on data analytics and platform enhancements, while general and administrative costs hit $439.1 million (16% of revenue).[36] Cost of revenues, at $558.5 million (20% of revenue), included data sourcing from third parties and researcher salaries.[36]| Category (2024, $M) | Amount | % of Revenue |
