"We migrated tens of millions of users from Auth0 to Stytch in less than a month. It was far and away the easiest migration I’ve ever worked on."

"Organization affiliation, and signup/login flows are nuanced when building B2B auth. With Stytch, we cut the time spent on auth to a tenth."

"Stytch won us over with their support on community Slack, well structured docs, and SDKs that were a drop-in replacement for Auth0."
