Atrium raises $65M from A16z to replace lawyers with machine learning

Let the computers do the legal busywork so attorneys can focus on complex problem solving for their clients. That’s the lucrative idea behind Atrium LTS, Twitch co-founder Justin Kan’s machine learning startup that digitizes legal documents and builds applications on top to speed up fundraising, commercial contracts, equity distribution, and employment issues. For example, one of its apps automatically turns startup funding documents into Excel cap tables.

Automating expensive legal labor has led to a rapid rise to 110 employees and 250 clients for Atrium including startups like Bird and MessageBird. Atrim only came of stealth a year ago with a $10.5 million party round before going into Y Combinator last winter. Today it announces its raised a $65 million round led by Andreessen Horowitz.

In characteristic dude fashion, Kan tells me “I’m pretty stoked about that because of having more resources for Atrium.” The venture firm’s partner Andrew Chen taking a board seat and famed co-founder Marc Andreessen joining as a board observer. “I wanted a visionary who’s always going to be pushing us to build something really big” Kan says. YC’s Continuity Fund and Ashton Kutcher’s Sound Ventures are also joining the round

With the massive new funding round, Atrium will be able to develop more internal tools it can use to crank out client work faster than its traditional competitors. “We can ultimately be this platform on top of which you’re building these legal business and eventually other professional services and software services” Kan explains,”They’re all sitting on top of the platform that understands legal documents.”

In more Atrium news, Y Combinator’s leading partner Michael Seibel will join the startup’s board too. And it’s acquired Tetra, a YC artificila intelligence startup that had raised $1.5 million to analyze voice, “to help us build our platform that understands and structures data” Kan tells me.

What Kan didn’t initially mention is that two Atrium’s co-founders, CTO Chris Smoak and legal partner BeBe Chueh have left. He later admitted that had transitioned out of the company several months before the new funding. “BeBe wanted to spend time working on family (she just got engaged); Chris and I disagreed on his job role” regarding the definition of the CTO position, Kan tells me. He’ll now be running Atrium with remaining co-founder Augie Rakow, formerly of mega-law firm Orrick, and Kan’s long-term business partner and former McKinsey analyst Nick Cortes.
