We’re excited to share that Clerk has raised $30M in Series B funding led by CRV, with participation from Stripe, and existing investors Andreessen Horowitz and Madrona. We will use this capital to expand our service beyond authentication, which identifies who a user is, and into authorization, which determines the permissions a user has.

To build our authorization service, we are partnering with Stripe to tightly integrate Stripe Billing. Together, we will create the easiest way to subscribe users to plans and grant access to features based on the plan that was purchased — all with no webhooks required.

Our Series B was led by Reid Christian at CRV, who we’ve been trading notes with for years. Reid and CRV are no strangers to modern developer tools, having invested in Vercel in 2015, during the earliest days of Next.js. We’re thrilled to be working with him for this next phase of Clerk and beyond.

Of course, none of this would be possible without our foundations in authentication, which we’ve been bolstering since 2019. Thanks to the dedication of our team, Clerk has experienced tremendous growth since our Series A last year, and is now managing over 16 million end-users! And, we’re facilitating over one new sign-up per second across verticals like SaaS, fintech, e-commerce, and more.

Our mission is to simplify the way you keep your users and their data safe, without forcing you to sacrifice high-quality user experience. We’ve been stalwart in our commitment to that mission for authentication, and you can be confident we will maintain our principles as we expand into authorization.
