Salus is the runtime control plane for AI agents.

As companies move agents from demos into production, they hit the same wall: an agent that can take real actions can also take the wrong one. Monitoring tells you after the fact. Evaluations tell you in a test environment. Neither stops a bad action in the moment it matters.

Salus sits between an agent and its tools and enforces policy on state-mutating actions before they execute. Not detection, not dashboards after the damage. Prevention, at runtime, in the path of the action.

We're a YC W26 company. The product works, the benchmarks are strong, and we're now focused on getting Salus into the hands of the teams who need it most. It's an early, fast-moving environment where what you do directly moves the company.
