Julianna Lamb is the co-founder and CTO of Stytch. Stytch builds user infrastructure and passwordless login to make it easy for developers to engage and authenticate their users. Julianna and her co-founder Reed McGinley-Stempel both worked on fraud and authentication at Plaid. Julianna also worked at Very Good Security. They were frustrated with the tools out there for developers. They built Stytch, the first company that has built a platform for passwordless authentication, so that any application or website can embed passwordless sign-up and login flows. Thousands of companies have chosen Stytch's APIs to eliminate the security and user experience shortcomings of password-based authentication.
