QM: A Multiplayer Agent Harness for Startups Built on Open Source
I built QM to solve the complexity of scaling AI agents across entire companies. Unlike personal assistants, QM gives every employee an isolated workspace while enabling seamless collaboration in Slack and on the web. Our open-source architecture lets you swap models like Pi, OpenCode, and Claude Code without vendor lock-in, ensuring secure, audited, and customizable deployments for your organization.
Most agents are designed like personal assistants. You can make one work for a whole company, but it quickly gets complex.

Aren't there a ton of products already doing this? Why not just use claude Cowork? Surely they're simpler/better/more featureful/developed than the alternatives here? What advantage does this have? Would love to see a 'QM vs Cowork' comparison!

I gave an agent its own Slack channel and it started scheduling meetings with other agents without me. I've never felt more like middle management

In a tangential earlier release, Gary Tan's own gstack:

Use Garry Tan's exact Claude Code setup: 23 opinionated tools that serve as CEO, Designer, Eng Manager, Release Manager, Doc Engineer, and QA

Love seeing this direction along with Buzz.
The hardest problem in multiplayer agents, at least for us, has not been the agent loop. It is scoping and QM's per-person scopes plus shared rooms is a sane answer for a company-wide assistant.
I build in the adjacent lane, AQ (aq.dev), a multiplayer coding harness where teams run Claude Code and Codex together), so seeing YC ship "a multiplayer agent harness for work" is validating and a little surreal.

I'll need to explore how they're doing org wide context and security for sure. This seems extremely complementary to my own coding tool which currently gives the best AI interface for individuals.
Would be cool if in a few epic tickets i'll have both their org wide architecture AND a productive individual coding interface :)

Is Hermes the best openclaw like agent as they mention running it before?
Also, what are power uses really using openclaw like systems for?

This was literally in YC's Request For Startups for Fall 2026: https://www.ycombinator.com/rfs#multiplayer-ai

It's fascinating to see new UI primitives and concepts get invented in the LLM era. The sea of creativity makes it hard to even understand most of what each new app does, and nobody describes them well. When I went to the Hermes agent web page, I was left with zero clue about what it did or what it could do. It took a bit of digging to find the right part of the qm page that helped me grok what was going on.
I've become attached to Orca (yc-backed) for managing coding sessions in the past week, but some sort of postgres session db is what's really lacking. So, maybe it's time to try qm.
