Casetext started out in 2013 as a crowdsourced law library — a sort of “Wikipedia meets reddit” for the law.
Ten years later, Casetext is one of the biggest mega wins to date in AI, capable of turning weeks of arduous legal work into hours or minutes. Just months ago it was acquired for $650 million dollars.
What happened between those two points?
For this episode of Main Function, YC President Garry Tan sits down with Casetext co-founder Jake Heller to learn the real story of their 10-year “overnight” success: the 3 a.m. origin story, how the company evolved as fast as tech would allow, and the “magic demo” that helped turn Casetext into a rocket ship.
