Brief

QM, an open-source multi-agent harness from Y Combinator (MIT-licensed), is cloud-first with native Slack and web UIs and is meant to be easy to customize like Hermes or OpenClaw. @snowmaker says they used QM daily for several weeks as YC’s primary agent, with Slack-based, visible workflows and full access to company data, eliminating copy/paste and enabling collaborative "multi-player" AI work.

Why it matters

@snowmaker reports using QM every day for several weeks as their primary agent harness inside Y Combinator; QM lives as a long-lived agent in company Slack with full access to company data, removing manual copy/paste and letting work happen in visible Slack channels.

Key details

  • Y Combinator open-sourced QM under an MIT license; the project is cloud-first, offers native Slack and web UIs, and is designed to be easy to customize (compared to Hermes or OpenClaw).
  • YC uses QM across accounting, legal, events, and engineering (including using QM to build itself), and @snowmaker calls it 'the first version of multi-player AI I've really seen work.'
Source evidence

I've been using QM every day for several weeks now, as my primary agent harness for getting work done within YC.

I've been struck by how useful it is to have a long-lived agent that lives in your company slack and has full access to your company data.

Before QM, a lot of work was copying and pasting between slack and some agent/LLM product.

With QM, that work gets done in slack channels where everyone can see it happening. It's the first version of multi-player AI I've really seen work.

Y Combinator (@ycombinator)

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.
