What Arga Labs does

We build environments to test your app and agents against the real world. Deploy your code/agent into a sandbox that runs against replicas of external services (Stripe, Slack, Google Drive, etc.). Twins support the same APIs, MCP tool calls & SDKs as the real software, and you can spin up thousands of instances in parallel and seed them using natural language. Run real workflows, surface edge cases, and observe how your code/agents actually behave before hitting production.

Real-world sandboxes to test agents

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

We build sandbox environments where developers can deploy their apps and agents against replicas of real external services like Stripe, Slack, and Google Drive. These replicas run the same APIs and tools as the real services, let you spin up thousands of instances, seed them in natural language, and run workflows that expose edge cases before your code hits production.

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

We live in San Francisco, CA, and after YC the company will remain based here.

Explain your decision regarding location.

San Francisco is where our team is located and where many developer tools and SaaS companies operate. Being here keeps us close to potential customers and engineering talent.
