Egoist Machines is building infrastructure for a world where personal context belongs to the individual rather than to apps and AI companies. Its first product, AI Passport, gathers the context a person generates across AI assistants and everyday apps into one portable profile the user controls.
Apps integrate through Sign in with AI Passport, a permissioned read/write loop that requests exact context fields for a stated purpose and duration, with receipts users can inspect and revoke, running on the company's own memory infrastructure with cryptographic per-user access control. AI Passport is free for individuals and offered to startups on a flat USD 1,000 per month managed-connect plan, three months free, six for YC companies. The company joined Y Combinator's Summer 2026 batch after its 2026 founding in San Francisco by Erin Meryl McGurk and Dr David Khachaturov.
