Jack Dorsey launches Buzz, a group chat app built for AI agents

Jack Dorsey's new startup released Buzz, a group chat platform designed to put human employees and their AI agents in the same conversation, positioning it as a challenger to Slack.

Why it matters: Buzz is part of a growing bet that workplace chat needs to be redesigned around AI agents as first-class participants rather than bolted-on bots, a shift several enterprise tools are racing to make as agentic AI moves from demos into daily workflows.
