FAQs about Clerk
Funding context and why this company shows up in venture coverage.
Clerk provides drop-in authentication and user management — sign-up, sign-in, multi-factor auth, organizations, and session handling — via React components and APIs so developers ship auth without building it from scratch.
Andreessen Horowitz (see /fund/andreessen-horowitz) backed early rounds. CRV (see /fund/crv) led the $30M Series B in 2024; Menlo Ventures (see /fund/menlo-ventures) co-led the $50M Series C in 2025.
Series C as of October 2025 ($50M). Prior Series B was $30M in January 2024. The company remains private.
Auth is table stakes for every app but expensive to build securely. Clerk's developer-first UX made it a default choice for startups — and identity infrastructure is increasingly relevant as AI agents need authenticated access.
No — Clerk remains a private company.
