Justin Kan

Justin Kan (born July 16, 1983) is an American internet entrepreneur and investor.

He is the co-founder of live video platforms Justin.tv and Twitch, as well as the mobile social video application Socialcam.

He is also the cofounder and former CEO of law-tech company Atrium.

In 2024, Kan announced that he had founded Stash, a payment and e-commerce platform for video game developers.

He was formerly a partner at Silicon Valley incubator Y Combinator.

His attempt to broadcast his entire life at Justin.tv, which he named after himself, popularized the term "lifecasting".

Kan also started a Reddit-style electronic music discovery platform, The Drop.

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 and Exec.

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.

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 and was one of the largest live video platforms in the world with more than 30 million unique users every month.

After Justin.tv launched in 2007, the site quickly began building subject-specific content categories like Social, Tech, Sports, Entertainment, News & Events, Gaming and others.

Gaming, in particular, grew very fast and became the most popular content on the site.

The company then decided to spin off the gaming content under a separate brand at a separate site.

They named it TwitchTV, inspired by the term twitch gameplay.

It launched officially in public beta on June 6, 2011.

Socialcam launched March 7, 2011, was bought by Autodesk July 17, 2012 for $60 million and was ended by Autodesk October 28, 2015.

Socialcam was a mobile social video application for iPhone and Android that allowed users to capture and share video online and on mobile, as well as via Facebook, Twitter, and other social networks.

At one point, the application eclipsed 2 million downloads and continued to add to its features list, most notably with the addition of video filters.

Justin Kan launched Exec on February 29, 2012, a new service to allow anyone to outsource anything they want for $25/hour.

Exec was co-founded with his brother Daniel Kan, former head of UserVoice business development, and Stanford graduate Amir Ghazvinian.

Justin.tv was closed on August 5, 2014, in an effort to focus further on Justin.tv's parent company, Twitch.

Twitch was acquired by Amazon.com in August 2014 for $970 million.

Exec was purchased by Handybook, a company founded by Oisin Hanrahan, Umang Dua, Ignacio Leonhardt, and Weina Scott, in an all-stock transaction in January 2014.

Kan became a partner at Y Combinator in March 2014, where he offered advice to the new startups in each batch.

The Drop is a Reddit-style electronic music discovery platform that launched early 2015.

Users can post and up-vote community-curated and sourced tracks.

It was founded by Kan and his college friend Ranidu Lankage.

In March 2017, Kan left Y Combinator to start his own incubator, Zero-F.

Kan publicly launched Atrium in 2017.

Kan raised $10.5 million in an initial "party" round of investment led by General Catalyst.

In September 2018, Kan raised a $65 million funding round led by Andreessen Horowitz.

At that time, Andrew Chen, Marc Andreessen and Michael Seibel joined the Atrium board of directors.

In March 2019, along with YouTube co-founder Steve Chen He became advisor to Theta, a peer-to-peer video streaming platform that uses blockchain technology.

Atrium closed operations in March 2020.
