About US

Were building the identity and access foundation for the agent-native era a new generation of systems where AI agents act on behalf of people and organizations to perform complex, real-time tasks.

Our mission is to empower developers and enterprises to build, deploy, and trust agentic applications with the same confidence they have in traditional softwarethrough secure, scalable, and context-aware infrastructure.

Were developing real-time, in-band guardrails that make it safe to move from human-driven workflows to fully autonomous, AI-powered systems. The goal : enable builders and security teams to operate with visibility, control, and trust as agents transition from experimentation to production.
