Charis Zhang

I’m a founder in San Francisco building Grata, an AI-native clinic for addiction recovery.

I was the CTO of Stiddle, where we built infrastructure for marketing teams to thrive in a cookieless world.

I dropped out of Berkeley after founding and selling Rizz AI, an AI application with over 500,000 users, and may have helped inspired Oxford's word of the year as well as a South Park episode.
