Committing to Agent Identity: Clerk raises $50m Series C from Menlo and Anthropic’s Anthology Fund

Clerk has raised a $50 million Series C funding round led by Menlo and Anthropic’s Anthology Fund, with participation from Georgian and previous investors, to further its mission of providing best-practice authentication with an exceptional developer experience. The company manages over 200 million users across more than 15,000 applications and is committed to staying at the forefront of evolving authentication needs, including the integration of passkeys and crypto wallets. As attention shifts towards AI, Clerk is preparing to address the need for secure agent identity with fine-grained permissions and auditability by aligning with forthcoming IETF standards. The funds will also enhance developer experience through deeper integrations and improved documentation, expand product offerings for multi-tenancy, billing, and business primitives, and invest in infrastructure reliability. Clerk expresses gratitude to its customers, partners, and team for their support as it embarks on this new phase in authentication development.
