Brief

Y Combinator open-sourced a multi-agent harness named QM, designed for company-wide use and easy customization similar to Hermes or OpenClaw. The MIT-licensed, cloud-first project provides native Slack and web UIs and is already used at YC across accounting, legal, events, and engineering — including for developing QM itself.

Why it matters

Y Combinator open-sourced a multi-agent harness called “QM” and released it under the MIT license.

Key details

  • QM is cloud-first, includes native Slack and web UIs, and is designed to be easily customizable like Hermes or OpenClaw.
  • YC uses QM internally across functions including accounting, legal, events, and engineering (they used it to build QM itself).

We’ve decided to open-source a multi-agent harness we use internally at YC.

We call it “QM” and it’s meant to be easy to customize, like Hermes or OpenClaw, but useful for a whole company. We use it across accounting, legal, events, and engineering (including building QM itself!).

The whole project is under an MIT license. It is cloud-first and has Slack and web UI natively.
