Case Study: Tome migrates millions of users with zero downtime using Stytch

Migrating millions of users and orgs from Auth0 to Stytch B2B

Tome, an AI-powered storytelling platform with more than 10 million users, needed to modernize authentication as its product scaled. Its legacy provider, Auth0, was causing reliability, documentation, and support issues, and Tome needed a better fit for its multi-tenant B2B model, improved login customization, and easier support for passwordless auth and account linking. To solve this, Tome chose Stytch B2B authentication.

Stytch helped Tome migrate tens of millions of users and thousands of organizations from Auth0 in less than a month with zero downtime. Using Stytch’s multi-tenant architecture, developer-friendly APIs, built-in account deduplication, and device fingerprinting, Tome improved reliability, reduced support tickets, prevented bot signups, and reallocated 2–3 engineers to core product work.
