Silicon Valley entrepreneur Justin Kan first put himself in the public eye over a decade ago when he spent eight months broadcasting a 24-7 live feed of his life online. This experiment in “lifecasting” led to the startup Twitch, which found a niche in livestreaming video game play. The company was purchased by Amazon for $970 million in 2014.

Now Kan is gaining visibility in the legal community through his “new law” venture Atrium. A group of venture capitalists led by Silicon Valley heavyweight Andreessen Horowitz just plowed $75 million into the year-old enterprise, which is split between a legal technology wing and an LLP. Former Orrick partner Augie Rakow, who advised Kan’s brother’s startup Cruise Automation when the autonomous vehicle company was acquired by General Motors for $1 billion, handles the law firm side.
