What Playgent does

When enterprise agents fail in production, the conditions that caused the failure are critical: user state, data, tool calls, and context. Without a way to recreate these conditions, teams can't fix what broke. Playgent provides infrastructure to create high-fidelity sandbox environments for AI agents. Our environments come packaged as a single MCP url where tool calls are mocked, authentication is abstracted away, and test data can be initialized via natural language or JSON specifications. Teams can use Playgent to reproduce production failures in safe, scoped environments that accurately reconstruct state. Finally, export runs as OTel traces from Playgent's environment to plug directly into your observability tools or RL pipelines.

Sandboxes for AI agents

What is your company going to make? Please describe your product and what it does or will do.

We build infrastructure that creates high-fidelity sandbox environments for AI agents. Our product lets teams reproduce production failures by mocking tool calls, abstracting authentication, and initializing test data using natural language or JSON. This helps engineers debug and fix issues that happen in complex AI agent deployments.

Where do you live now, and where would the company be based after YC?

We live in San Francisco, CA, and the company is based here after YC as well.

Explain your decision regarding location.

We are located in San Francisco because of the tech talent concentration and proximity to enterprise customers who build AI agent products in healthcare IT.
