“We never wanted user accounts. We didn’t want to add that friction to checkout. So when we saw what Stytch could do and dug into the possibilities of OTPs, it just clicked for us on the product side. It’s ideal from a conversion standpoint, because it limits the amount of fields to fill out and tasks to complete at checkout. Since over 95% of our end-user traffic is on mobile, it just makes sense.”
— Kristofor Erickson, Olla CTO
“The Stytch approach to IAM is both elegant and forward looking and we are really excited about building out the web3 space together with their amazing team. The Stytch login will first power our token sale at getverse.com, and then be rolled out to the entire Bitcoin.com ecosystem. With their detailed documentation, SDKs for the most popular programming languages, and strong development support, the whole process has been very straightforward and easy.”
— Paul Bergamo, Product Manager, Bitcoin.com
“Stytch's documentation was very easy to understand and read. After we made the switch from Auth0 to Stytch, we saw a 62% improvement in its sign-up conversion rate.”
— Jack Grzechowiak, Lighthouse software engineer
“Health care professionals regularly use many different platforms. As a result, keeping track of login credentials is laboriously difficult. Offering simple, passwordless authentication through Stytch has been incredibly compelling to our users. The implementation process was straightforward, and their engineering team has gone above and beyond in offering support.”
— Daniel Wilson, co-founder, COO, Head of Product
“We evaluated a few different providers. As an engineer, Stytch came out on top due to their clear API docs and flexibility. Stytch is very modular in terms of configuring passwordless auth. You can fit solutions together in any number of ways, depending on your needs, and customize them to your app without having to invest extra engineering time.”
— Daniel Ciao, Alice co-founder and software engineer
“When we started thinking about building our auth, I looked at three solutions: Auth0, Magic Link, and Stytch. It became clear playing with each that Stytch was going to be the most flexible. With Auth0, you had to open the email in the same browser you requested the login from, which didn’t work for us. And Magic didn’t have the same level of API exposure.”
