Career

[edit]

Justin.tv

[edit]

In 2007, Justin Kan and partners Emmett Shear, Michael Seibel and Kyle Vogt started Justin.tv, a 24–7 live video feed of Kan's life, broadcast via a webcam attached to his head.[7] Kan was 23 years old at the time.

Kan's "lifecasting" lasted about eight months. Kan's concept attracted media attention, and resulting interviews with him included one by Ann Curry on the Today Show. Viewers accompanied Kan as he walked the streets of San Francisco, sometimes involved in both pre-planned events (trapeze lesson, dance lesson) and spontaneous situations (being invited into the local Scientology center by a sidewalk recruiter).

Afterward, the company transitioned to providing a live video platform so anyone could publish a live video stream. Justin.tv, the platform, launched in 2007[8][9] and was one of the largest live video platforms globally with more than 30 million unique users every month.

Justin.tv was shut down on August 5, 2014, in an effort to focus further on Justin.tv's parent company, Twitch.[10][11][12]

Twitch

[edit]

After Justin.tv launched in 2007, the site added subject-specific content categories like Social, Tech, Sports, Entertainment, News & Events, Gaming and others. Gaming quickly grew to become the most popular content on the site.[13]

The company then decided to spin off the gaming content under a separate brand at a separate website. They named it TwitchTV, inspired by the term twitch gameplay. It launched officially in public beta on June 6, 2011.

Twitch was acquired by Amazon.com in August 2014 for $970 million.[14][15]

Socialcam

[edit]

In March 2011, Kan launched Socialcam, a smartphone application that allowed users to capture and share videos. Socialcam was bought by Autodesk in July 2012 for $60 million and was eventually shut down in October 2015.[16][17] The application reached 16 million downloads before its acquisition.[18]

Exec

[edit]

Kan launched Exec on February 29, 2012 with the goal of allowing anyone to outsource miscellaneous tasks for $25/hour. Exec was co-founded with his brother Daniel Kan, former head business development at UserVoice, and Amir Ghazvinian.[19]

In January 2014, Exec was purchased by Handybook, in an all-stock transaction.[20]

Y Combinator

[edit]

Kan was a member of the first batch of YC-funded startups in 2005 for Kiko Calendar, and was funded by YC again for Justin.tv[5] and Exec.[21] Kan became a partner at Y Combinator in March 2014, where he offered advice to the new startups.[22] In March 2017, Kan left Y Combinator to start his own incubator, Zero-F.[23]

The Drop

[edit]

The Drop is a Reddit-style electronic music discovery platform that launched in early 2015. Users can post and up-vote community-curated and sourced tracks. It was founded by Kan and his college friend Ranidu Lankage.[24]

Atrium

[edit]

In 2017, Kan launched technology-enabled law firm, Atrium.[25] Kan raised $10.5 million in an initial "party" round of investment led by General Catalyst.[26] In September 2018, Kan raised an additional $65 million funding round led by Andreessen Horowitz. At that time, Andrew Chen, Marc Andreessen and Michael Seibel joined the Atrium board of directors.[27] Atrium closed operations in March 2020.[28]

YouTube

[edit]

Justin Kan started a YouTube channel in 2021.[29] In February 2021 he announced that fans could collect his YouTube videos as non-fungible tokens on OpenSea.[30][31]

Fractal

[edit]

Kan started Fractal.is in December 2021 as a marketplace for Solana-based NFTs. Players could buy NFTs directly from game companies or through peer-to-peer trading. In April 2022, Fractal raised $35 million in a seed round led by Paradigm and Multicoin Capital. Other investors include Andreessen Horowitz (a16z), Solana Labs, Animoca Brands, Coinbase Ventures and Terraform Labs CEO Do Kwon, and others.

In 2024, Fractal was renamed to Stash, and pivoted to include a suite of products which allow game developers to interface directly with their customers.[4]

Career

Justin.tv and early innovations

Justin Kan co-founded in 2007 alongside , , and , launching the platform on March 19 of that year as a pioneering experiment in live video broadcasting. The core concept centered on 24/7 "lifecasting," where Kan streamed his personal life continuously via a head-mounted , creating an unfiltered, real-time window into daily activities and interactions to explore new forms of user-generated live video content. This approach aimed to transform viewers into participants through integrated chat features, fostering a community around the broadcasts and challenging traditional media boundaries by enabling anyone to become a "reality star." The development of Justin.tv presented significant technical hurdles, particularly in mobile broadcasting and server infrastructure. The team relied on prototype cameras that streamed over cellular data networks, which required innovative solutions to handle unreliable connections and latency in real-time transmission. Server scaling proved equally demanding, as the platform negotiated with content delivery networks (CDNs) to manage surging live video traffic, ensuring stability as broadcasts expanded beyond Kan's personal feed. These challenges were compounded by the need to process and distribute high-bandwidth video streams efficiently in an era when such technology was nascent. By October 2007, Justin.tv had opened to , evolving from a singular lifecasting experiment into a general live-streaming platform that allowed users worldwide to create and share their own channels. This shift drove rapid adoption, reaching 1 million registered users within eight months and scaling to 17 million monthly unique visitors by late 2010, reflecting its impact on democratizing live video creation. Justin.tv ceased operations on August 5, 2014, as the company pivoted resources to other services, including the gaming-focused spin-off Twitch.

Twitch founding and acquisition

In June 2011, Justin Kan and his co-founders spun off the gaming-focused section of Justin.tv into a dedicated platform called Twitch, aiming to capitalize on the growing popularity of video game live streaming. This separation allowed Twitch to target gamers specifically, building on the live video technology developed at Justin.tv while narrowing its scope to esports and interactive broadcasts. Kan, as a co-founder of both ventures, played a key role in the initial strategy and leadership during the transition, though Emmett Shear assumed the CEO position to guide Twitch's independent operations. Twitch experienced explosive growth in its early years, attracting gamers through features like real-time chat integration that fostered interaction between streamers and viewers. The platform also became a hub for , supporting broadcasts of major tournaments and enabling competitive streamers to build audiences and monetize content, which helped solidify its position in the gaming ecosystem. By the end of 2014, Twitch had surpassed 100 million unique monthly viewers, more than doubling its audience from 45 million in 2013 and accounting for a significant portion of global . The platform's rapid ascent culminated in its acquisition by Amazon on August 25, 2014, for $970 million in cash, marking one of the largest tech exits of the year. As a co-founder, Kan received a substantial payout from the deal, which validated Twitch's model and his vision for . Following the acquisition, Kan transitioned out of day-to-day leadership at Twitch to pursue new ventures, leaving Shear to oversee integration with Amazon.

Additional startups (2011–2016)

In March 2011, Justin Kan co-founded , a mobile application enabling users to capture, edit, and share short videos directly from their smartphones, positioning it as an early competitor in the emerging social video space. The app quickly gained traction, amassing over 16 million downloads by mid-2012 through features like simple filters and social sharing integrations. In July 2012, acquired for $60 million to bolster its mobile and capabilities, integrating the technology into its broader ecosystem. eventually discontinued the app in October 2015 as part of streamlining its product portfolio. Shortly after, in February 2012, Kan launched Exec, initially as an on-demand errand service allowing users to hire help for tasks like laundry or groceries at a flat rate of $25 per hour via a mobile app. Co-founded with his brother Daniel Kan and Amir Ghazvinian, the platform pivoted toward specialized services, particularly house cleaning, to address market demand for reliable on-demand home maintenance. This shift helped Exec expand in the competitive "Uber for services" landscape, focusing on vetted providers and instant booking in urban areas. In January 2014, New York-based Handybook acquired Exec for under $10 million, primarily to gain its West Coast operations and user base, merging the teams to scale nationwide cleaning services. In early 2015, amid his ongoing role at Twitch, Kan created The Drop, a community-driven platform modeled after for discovering and sharing tracks, where users could upvote content and rely on moderators for curation. Designed to foster a constant stream of new music recommendations, it emphasized user-generated playlists and viral sharing but struggled to achieve widespread adoption in the crowded music discovery market. Limited public information exists on its eventual closure, though it appears to have ceased operations quietly within a couple of years without a major acquisition or pivot announcement. These ventures overlapped with Kan's involvement at Twitch, where he served as co-founder from 2011 to 2014, demonstrating his pattern of rapid experimentation in consumer technology by launching and exiting short-lived apps while scaling the streaming platform. This parallel entrepreneurship was partly enabled by Twitch's growing revenue, which provided resources for quick pivots in mobile and service-based innovations.

Y Combinator involvement

In March 2014, Justin Kan joined as a full-time partner, building on his part-time involvement with the accelerator since 2011. As a member of YC's inaugural Summer 2005 batch with , Kan brought extensive founder experience from building and scaling multiple ventures, including the live-streaming platform that evolved into Twitch. In his role, he focused on advising startups across YC batches on key aspects of growth, such as product development, strategies, and operational scaling, drawing directly from his successes and challenges in launching consumer-facing tech products. Kan particularly emphasized practical insights from his pioneering work in lifecasting and live video, where he had broadcast his daily life 24/7 via a head-mounted for eight months to test the viability of real-time streaming technology. This hands-on expertise informed his , helping founders navigate engagement, , and in video-centric applications. He shared advice on resilience during pivots—lessons honed from transitioning into a gaming-focused powerhouse—and on securing by demonstrating user traction in competitive media spaces. During his three-year tenure, Kan's guidance had a notable impact on YC batches from Winter 2014 to Winter 2017, where he supported emerging companies in video streaming and gaming by leveraging his network and to refine go-to-market strategies and foster partnerships. His involvement helped amplify YC's emphasis on live entertainment innovations, echoing the trajectory of his own ventures. In March 2017, Kan departed YC to launch Zero-F, his personal investment firm aimed at more hands-on support for early-stage founders seeking deeper operational involvement beyond traditional advising. In 2017, Justin Kan co-founded Atrium, a legal technology company aimed at disrupting traditional law firm services for startups, alongside Augie Rakow (a former partner at Orrick, Herrington & Sutcliffe), Bebe Kim (previously at LegalZoom and founder of AttorneyFee.com), and Chris Smoak (a Y Combinator alum and serial software entrepreneur). Kan, leveraging his background from co-founding Twitch and his time as a Y Combinator partner, sought to assemble a team with expertise in tech innovation and legal operations. Atrium's mission centered on simplifying legal processes for early-stage companies through a combination of platforms and flat-fee legal services, targeting pain points like , hiring, and incorporations that were often opaque and costly under traditional models. The company developed tools such as for document management and Hiring for agreements, while employing in-house lawyers to provide efficient, predictable , positioning itself as a "modern " for tech startups. This hybrid approach aimed to blend with to reduce reliance on hourly billing and improve accessibility. Atrium quickly secured significant funding, raising a total of $75.5 million across multiple rounds, including a $10.2 million seed from General Catalyst and a $65 million Series B led by , with participation from and over 100 other investors. This capital enabled rapid expansion to over 100 employees, including attorneys and engineers, and served hundreds of startup clients within its first few years. Despite initial momentum, Atrium faced substantial challenges in navigating legal industry regulations, such as state bar rules on non-lawyer and ethical constraints on fee structures, which limited its ability to fully integrate without compromising compliance. The company also struggled with , as its subscription-based software and services failed to deliver the efficiency gains needed to outpace established firms, exacerbated by premature scaling and internal pivots from services to a software-only model. These issues culminated in the company's closure in March 2020, with all employees laid off and remaining funds returned to investors. The Atrium experience highlighted key lessons on the difficulties of blending with highly regulated industries like , where entrenched professional norms and regulatory hurdles often impede rapid innovation. Kan later reflected that building a "full-stack" services company required deeper and a stronger focus on user needs from the outset, rather than aggressive hiring and expansion without validated market demand. Ultimately, the venture underscored the risks of applying consumer tech playbooks to B2B , where trust, compliance, and incremental improvements prove more critical than disruptive scale.

Gaming and media ventures (2021–present)

In August 2021, Kan co-founded , a commerce protocol that enables developers to integrate -based payments and features into applications, raising $14 million in seed funding led by Andreessen Horowitz's crypto arm in October 2022. In December 2021, Justin Kan co-founded , a Solana-based NFT marketplace targeted at gaming creators to facilitate the trading of in-game assets and digital collectibles. The platform aimed to empower developers and players by providing tools for minting, buying, and selling NFTs directly within gaming ecosystems, drawing on Kan's prior experience in to address the growing intersection of and interactive entertainment. By early 2024, rebranded to Stash, shifting its focus from NFTs to a (D2C) platform for game developers, offering tools such as integrated payments, customizable webshops, and game launchers to enhance player engagement and outside traditional app stores. This pivot emphasized seamless in-game commerce and retention features, like one-tap checkouts and incentives, enabling studios to build direct relationships with users and bypass platform fees. In September 2025, Stash appointed former Homa president Henry Lowenfels as CEO, with Kan continuing as co-founder focused on strategic development of these game developer tools amid evolving trends in AI and player-centric distribution as of November 2025. In November 2024, Kan co-founded Thin Ice Entertainment with artist manager and investor Nicholas Parasram, establishing a firm specializing in music and , including support for producers and emerging artists through services like , distribution, and . The venture seeks to bridge traditional entertainment with digital innovation, leveraging Kan's entrepreneurial background to provide comprehensive career development for talent in media and gaming-adjacent spaces. Around 2021, Kan launched his personal YouTube channel @JustinKanTV, where he shares content on startup advice, personal life stories, and entrepreneurial insights, including episodes under the "Startup Stories" series that feature interviews and reflections on building companies like Twitch. The channel serves as a platform for Kan to discuss lessons from his career, such as pivoting ventures and fostering innovation in tech and media.
