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.
