Jack Dorsey Launches Buzz for Teams and AI Agents

Block co-founder Jack Dorsey is moving into workplace collaboration with Buzz, an open-source platform designed for teams in which people and AI agents work side by side. The service combines Slack-style real-time conversations with GitHub-like project management, reflecting a broader shift toward software that treats autonomous agents as active participants rather than add-on tools. Its open and decentralized approach could appeal to organizations seeking greater control over workplace technology and data.

Dorsey has unveiled Buzz as a model-agnostic platform that companies and developers can customize and deploy on their own infrastructure. Users can control the source code and tailor permissions, data handling and AI-agent integrations to internal requirements. By offering an alternative to closed collaboration suites such as Slack, Buzz aims to reduce dependence on a single software vendor or AI model while giving technical teams more flexibility over how human and automated work is coordinated.
