Jack Dorsey's Block has launched Buzz, a group chat platform designed to integrate human teams with AI agents, positioning itself as an open-source, model-agnostic alternative to Slack and GitHub.

This Wire brief sits within Fusion42's coverage of Collaboration Tools and AI Agents.

◆ ◆ The Wire takeaway

If you're building AI agents for enterprise use, your chat layer just got commoditised by someone with Slack-scale distribution. Block's move signals that agent orchestration happens inside collaboration tools now, not on top of them—your integration moat is gone.
