Jack Dorsey, the co-founder of Twitter and Block, announced a new application called Buzz on July 21, 2026, positioning it as a challenger to Slack and GitHub in the rapidly evolving market for AI-native workplace tools. Buzz is described as a group chat platform designed for teams of both people and AI agents, built to reduce what Dorsey characterized as an unhealthy dependency on incumbent collaboration tools. For ongoing AI industry coverage, the launch reflects a growing trend of entrepreneurs building products specifically for a workplace where human employees and autonomous agents work side by side.
What Buzz Does Differently
Dorsey announced the product in a post on X, writing that Buzz is "model-agnostic, decentralized, self-sovereign, and open source." The platform was built by Block, the financial technology company Dorsey also leads, which operates products including Square, Cash App, Afterpay, and Tidal.
According to TechCrunch, Buzz's core utility lies in merging several different workflows into a single workspace. Visually, it resembles Slack, but it incorporates native AI agents and the ability to manage GitHub projects from the same interface. The idea is to eliminate the friction of context-switching between a chat application, an AI assistant, and a code repository, three tools that modern software teams rely on constantly.
Because the platform is open source, developers can customize their own Buzz instance to match the specific needs and workflows of their team. If a team requires a feature that does not exist, they can build and deploy it themselves with full access to the source code, rather than waiting for a vendor to add it to a product roadmap.
The AI Agent Workplace
Buzz arrives at a moment when AI agents are moving from experimental novelties to integral parts of enterprise workflows. Increasingly, companies are deploying autonomous or semi-autonomous AI systems that can write code, answer questions, manage projects, and interact with external services. The challenge this creates is one of coordination: when an employee is managing tasks across Slack, a code repository, and an AI assistant, the cognitive overhead of keeping everything synchronized becomes significant.
Dorsey's pitch is that Buzz solves this problem by treating AI agents as first-class participants in the workspace, not as external plugins or integrations bolted onto an existing chat platform. An agent can participate in conversations, update project statuses, and execute tasks within the same environment where human teammates are collaborating.
The model-agnostic design is particularly significant. Rather than tying Buzz to a single AI provider, the platform allows teams to use whatever large language model best suits their needs, whether that is a frontier model from OpenAI or Anthropic, an open-weight model from Meta or Alibaba, or a locally deployed model running on the team's own infrastructure. This flexibility aligns with a broader industry trend toward avoiding vendor lock-in as AI model capabilities and pricing shift rapidly.
Dorsey's Track Record
Dorsey is one of the most recognizable figures in consumer technology. He co-founded Twitter in 2006 and served as its CEO in two separate stints before departing the board in 2021. He also co-founded Block, originally named Square, in 2009 and has served as its chief executive. His previous ventures have been marked by a strong emphasis on open standards and decentralization.
Dorsey has been a vocal advocate for decentralized protocols and open-source software. He supported the development of Bluesky, a decentralized social media protocol originally incubated at Twitter, and has promoted Bitcoin and blockchain technology as tools for creating more open financial systems. Buzz's emphasis on being decentralized and self-sovereign fits squarely within this philosophy.
A Competitive Landscape
Buzz enters a crowded market. Slack, owned by Salesforce, dominates enterprise team messaging, while Microsoft Teams leverages its integration with the broader Microsoft 365 ecosystem. GitHub, owned by Microsoft, is the de facto standard for code hosting and project management among software teams. Both have been aggressively adding AI capabilities, with Microsoft Copilot integrated across Teams and GitHub.
Dorsey is not the only entrepreneur pursuing AI-native alternatives to established collaboration tools. Paradigm partner and chief technology officer Georgios Konstantopoulos recently unveiled a similar open-source product called Centaur, which he describes as a virtual employee that runs either inside Slack or via an application programming interface. The emergence of multiple independent efforts suggests that there is genuine demand for tools that are designed from the ground up for an AI-augmented workforce.
Open Source as a Wedge
Dorsey's decision to make Buzz open source could be a meaningful differentiator. Enterprise software buyers are increasingly wary of vendor lock-in, particularly in the AI space where the pace of change makes long-term commitments risky. An open-source platform that teams can self-host and customize offers a level of control that proprietary alternatives cannot match.
However, open-source business models face well-documented challenges around monetization and sustainable development. Block's backing gives Buzz resources that most open-source projects lack, but the company will need to articulate a clear path to revenue if Buzz is to become more than a side project. Dorsey did not specify in his announcement how Buzz would generate revenue or whether it would be offered as a paid product, a managed cloud service, or entirely free.
Block did not provide a launch date for general availability, and details about pricing, supported integrations, and enterprise features remain limited. The product is currently available as an open-source project.
