Deffai

Headquartered in San Francisco, Deffai is an AI-native VC-backed seed-stage startup building an AI platform for simulating FDA regulatory intelligence, built together with former FDA reviewers. We help therapeutics companies and their investors anticipate regulatory outcomes. We are ambitious builders with diverse technical backgrounds building vertical AI solutions in a deeply regulated space. Work closely with former FDA decision-makers to redefine the future of biotech approvals. Backed by top-tier tech investors in the SF Bay Area, with advisors from GitHub, OpenAI, and Mercor. Are you an ambitious builder who wants to do more and push the boundary of what's possible? Join our team! Size of the opportunity: FDA accounts for 20% of the U.S. economy alone. Food, drug, and cosmetics. Beyond the U.S., other countries and regions including Canada, Europe, and Japan all have their own FDA with similar frameworks.
