Clerk: React-Friendly Authentication Solution Company Raises $30 Million

By Noah Long • Jan 24, 2024

Clerk – a developer tools company known for its React-friendly authentication solution – announced it raised $30 million in Series B financing led by CRV, with participation from Stripe and existing investors Andreessen Horowitz and Madrona. The funding will be used to expand its service beyond authentication, which identifies who a user is, and into authorization, which determines the permissions a user has.

The funding from Stripe marks the beginning of a strategic partnership between the two companies. And as the industry-leading billing solution, Stripe Billing helps developers create and manage user subscriptions. Since permission to access certain features usually depends on the user’s subscription plan, Clerk requires a tight integration with Stripe Billing to create a robust authorization solution.

Since announcing the Series A funding last January, Clerk has grown from 1 million to over 16 million managed users, and now facilitates more than one sign-up per second. The company has amassed over 1,300 paying customers across several verticals, including SaaS, AI, fintech, and e-commerce.

Clerk’s Series B funding round will be instrumental in accelerating its product development, growing its team, and furthering its mission to ensure every developer can easily implement safe and user-friendly security.

KEY QUOTES:

“The <SignIn/> and <UserProfile/> components from Clerk have already set a new standard in authentication, and proven that components are the new APIs. We’re thrilled to support Clerk as they apply their solutions to the authorization market.”

– Reid Christian, General Partner at CRV

“Our customers have been asking us to integrate with Stripe since the week we launched. Billing information is notoriously challenging to sync with authorization engines, so it’s natural that developers have been asking us to provide a solution.”

– Colin Sidoti, CEO of Clerk
