Stytch

Stytch, founded in 2020, is a developer-focused identity platform providing authentication, authorization, and fraud prevention through a single integration. The company's core product, the Stytch Identity Platform, is designed to handle large-scale identity infrastructure, processing billions of authentication requests and millions of daily login events.
