Agent 37 on the record

What they shipped

  • From its YC profile: * Ready to Use Instantly: Skip the complex server setup. It comes pre loaded with top AI Agents (like Claude Code and Hermes) so your agents can start working immediately. * Keep Your Work Safe: Unlike other systems that delete everything when they finish a task, these sandboxes remember your files, code, and settings forever until you delete them. * Pay Only for What You Use: Stop paying for idle servers. You pay a tiny fee to store your files, but you only pay for compute power during the exact minutes your AI is actively running. (source)
  • Its own site describes it as: "Create an always-on Hermes, OpenClaw, or custom agent with one API call. Files persist between runs. Metered per minute, no subscription." (source)
