Runtime

Runtime is a Y Combinator-backed company that let all your team ship safely with coding agents. Based in San Francisco, USA, the company participated in the Spring 2026 batch of Y Combinator.

Runtime (runtm.com) gives engineering teams control and visibility to enable anyone in their org to use coding agents securely.

Eng leaders rolling out coding agents have no way to see what's happening, set boundaries, or safely let non-engineers use them. We provide sandboxed environments, session-level observability, and configurable guardrails so anyone on your team can ship with coding agents without breaking prod.

Runtime was part of Y Combinator's Spring 2026 cohort, has a team of approximately 3 employees, and is actively operating.
