He also runs Screendoor LP, backing underrepresented emerging venture managers. His 'Bottom Up Economy' thesis targets scrappy teams of 5-50 taking on category incumbents - and his portfolio hits like Chime, Plaid, and Gusto prove the thesis works. A prolific blogger, former TV assistant, and forever a product person at heart.
Autosana AI is the first agentic QA platform for iOS, Android, and Web. Founded by Yuvan Sundrani and Jason Steinberg in June 2025 and backed by Y Combinator (S25 batch), Autosana replaces brittle test scripts with AI agents that navigate apps like real users, described in plain English. The company raised $3.2M in February 2026 from YC, Pioneer Fund, Phosphor Capital, DeVC, 468 Capital, and angels including Paul Graham. Revenue is growing 100%+ month over month, and the platform now protects apps serving over 100 million daily active users. The name comes from the Latin 'autosana' — to heal oneself — reflecting tests that evolve alongside the product rather than breaking on every UI change.
