About Runtime
Summary
Runtime builds an agent harness that lets payment teams deploy and run AI agents across operations, risk, compliance, and support without engineering involvement. Each agent runs in its own sandboxed cloud environment, connects to existing channels like Slack or email, and pauses to request approval before taking action. This replaces manual review queues and the need for engineers to build, host, or monitor every internal automation.
Business model
Free tier plus a paid plan for teams running mission-critical operations.
Go-to-market
Payment operations teams at fast-growing companies are the primary buyers, reached through self-serve sign-up and direct sales demos.

Build and run internal agents, without managing the infrastructure
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. We're live with fast-growing YC scaleups empowering their Engineers, PMs, designers, marketers, and ops to contribute to their codebase or build prod-grade zero-to-one apps.
