Everything on anyone.
Autumn is building the world’s most comprehensive index of people and companies. Information about anyone is scattered across profiles, filings, event pages, code, posts, news, and the rest of the open web. Autumn reads across these sources, determines which records belong together, and creates a complete, source-backed profile of people and companies - including relationships, work history, contact information, and digital footprint. Search for anyone, build a cohort, or research a company through our API. Autumn AI is a Y Combinator company (Winter 2026). YC-listed status: Active.
