Stytch
Identity platform with auth, B2B SaaS organization management, B2C UI components, and fraud protection for humans and AI agents.
About
Stytch is an identity platform for authentication, authorization, and security. The product covers passkeys, passwords, SAML SSO, multi-factor auth, multi-tenancy, and machine-to-machine auth, with both pre-built UI components and headless SDKs. Used by B2B and B2C apps including HubSpot, Genomoncology, Crossmint, and Spydr.
Founded by Julianna and Reed, who previously worked together at Plaid. Their pitch: engineers waste time building auth instead of their own product, so Stytch handles it.
Backed by Thrive Capital, Index Ventures, Benchmark, and Coatue. Offices in San Francisco and New York. Recently joined Twilio to build what they call the intelligent identity layer for the internet.
