WorkOS lands $100M, hits $2B valuation

WorkOS, a platform for adding enterprise features to applications, has raised $100 million in a Series C funding round. This latest investment values the company at $2 billion, doubling its previous valuation.

The round was co-led by Meritech and Sapphire, with significant contributions from existing investors Audacious, Craft, and Abstract, alongside new backers including Greenoaks. This infusion of capital marks a strong endorsement for WorkOS's strategy in the rapidly evolving software landscape.

The company highlighted its growing adoption by leading AI firms, including OpenAI, Anthropic, and xAI. These companies reportedly rely on WorkOS to meet immediate enterprise requirements like Single Sign-On (SSO), SCIM provisioning, and robust permissioning, often from day one of product development.

Building for the Agentic Era

WorkOS founder Michael Grinich framed the funding as fuel for the next phase of software development, characterized by the rise of autonomous agents. He emphasized that as software becomes more intelligent and autonomous, trust, authentication, and auditability become paramount constraints.

"WorkOS was built for this moment," Grinich stated. The platform has expanded beyond its initial authentication focus to encompass granular permissions, integrations, encryption, abuse detection, and more. The company also pointed to its infrastructure's reliability, citing five-nines uptime and billions of API requests processed monthly.

This new funding is earmarked for accelerating the development of features that enable secure and reliable agentic software by default. WorkOS aims to empower developers, from those building weekend projects to those shipping enterprise-grade AI products, to do so faster and more securely.
