Y Combinator open-sources internal multi-agent framework QM under MIT

Y Combinator (YC) announced on August 1 that it has open-sourced its internal multi-agent orchestration framework QM under the MIT license. The project is currently in early experimental stage but has been deeply used across YC, aiming to provide enterprises with easy-to-customize agent orchestration capabilities and a starting foundation. The release offers a highly practical reference implementation for other companies exploring multi-agent workflows.

Confirmed

Core features: QM is cloud-native and natively supports Slack and Web UI. It emphasizes easy customization, offering an experience similar to Hermes or OpenAI Swarm, and supports triggers like Crons and Webhooks, with enterprise knowledge base integration. It also provides AI workspaces with isolated memory, permissions, and persistent sandboxes for each employee and project.
Use cases: QM has been widely used across YC in accounting, legal, event planning, and engineering development (including QM's own development), effectively improving internal efficiency.
License: MIT license, allowing free use, modification, and distribution.

Why it matters

QM demonstrates the versatility of multi-agent frameworks in real enterprise environments. By open-sourcing its internally used tool, YC provides a highly practical starting base for other companies to explore and customize multi-agent workflows.
