In 2009 he co-founded Quora with Adam D'Angelo, and he worked there until 2012. In 2015 he started Expo, an open source framework and cloud platform (Expo Application Services, or EAS) for building iOS, Android and web apps in JavaScript with React Native. Public profiles list him as an Expo co-founder, and Wikipedia describes him as its president. Tracxn also lists him as a co-founder of Graph Ventures.
Crunchbase lists 50 personal investments and NFX Signal lists 48 investments on record. Both put him in the San Francisco Bay Area. PitchBook shows 75 investments and 46 exits for his angel profile.
Tracxn names Opendoor, Amplitude and Zenefits among his portfolio exits. Crunchbase also shows earlier seed-stage investments such as Lunchclub (2019) and Raycast.

The round also included Y Combinator, Script Capital, Eight Capital, AIP Seed and several developer-tool founders as angels.
NFX Signal shows activity at pre-seed, seed, Series A and Series B in AI, SMB software, games and real estate/proptech. Much of his AI and tooling activity is technical and developer-oriented, which fits his work on Expo.
