Jack Dorsey is taking on Slack with Buzz, a group chat platform for teams and their AI agents

Why it matters

Buzz represents a fundamental shift in workplace collaboration tooling: AI agents are no longer bolt-ons to existing platforms, but first-class participants in team workflows. This challenges Slack's market position and signals how founding teams are rethinking communication infrastructure for agentic workforces.

Key signals

  • Jack Dorsey launching Buzz—group chat platform designed for humans + AI agents collaboration
  • Direct Slack competitor positioning agents as native participants, not integrations
  • Workplace collaboration infrastructure shift toward agentic-first design
  • Published July 21, 2026—breaking product launch

The hook

Not a chat app. A workspace where humans and AI agents collaborate in real-time—Jack Dorsey's new Slack competitor just shipped.

Buzz is a group chat platform for the workplace that puts humans and their AI agents in the same conversation.
