YC Software’s QM is an open-source multiplayer agent harness for Slack and web-based startup workflows

The GitHub repository describes QM as a multiplayer agent harness that gives each employee or shared room its own isolated workspace, memory, files, permissions, crons, web apps, and durable sandbox. It supports Slack and web collaboration while allowing teams to use different agent harnesses and models, including Pi, OpenCode, Codex, and Claude Code.

QM reflects a shift from solo AI assistants toward team-native agents designed for organizational workflows and shared context. Its vendor-flexible architecture suggests growing demand for open, interoperable AI infrastructure that startups can adapt without locking into a single model provider.
