Jack Dorsey, the co-founder of Twitter and Block, has announced a new application called Buzz that aims to disrupt the workplace communication market. Positioned as a direct challenger to established platforms like Slack and GitHub, Buzz is a group chat platform designed to bring humans and their AI agents into the same conversations. Dorsey announced the launch on X, describing Buzz as “model-agnostic, decentralized, self-sovereign, and open source.”
Buzz was developed by Dorsey’s company Block, which already operates a suite of prominent financial and creative tools including Square, Cash App, Afterpay, and Tidal. This product appears to be more than a side project; it represents a strategic move to integrate AI agents into everyday teamwork. As startups increasingly rely on automated AI agents to handle coding, data analysis, and other tasks, Buzz aims to consolidate these workflows into a single workspace. The platform looks similar to Slack but includes native AI capabilities and the ability to manage GitHub projects directly from the chat window.
Key Features of Buzz
One of the standout aspects of Buzz is its open-source nature. Developers can fork the code, customize their own instance of Buzz, and deploy it for their team’s specific needs. This flexibility allows teams to build new features themselves if they are not available out of the box, since they have full access to the source code. Buzz also emphasizes decentralization and self-sovereignty, giving users control over their data and communication infrastructure.
The platform is already available as a free desktop app for macOS, Windows, and Linux, with the source code uploaded to GitHub. While Buzz is in its early stages, it has generated significant interest among developers and tech enthusiasts who are eager to reduce dependency on proprietary tools like Slack and GitHub.
Background on Jack Dorsey and Block
Jack Dorsey is a well-known figure in the technology industry, having co-founded Twitter (now X) in 2006 and later co-founding Square, which evolved into Block. He served as CEO of both companies simultaneously until stepping down from Twitter in 2021. Under his leadership, Block has expanded beyond payment processing into music streaming (Tidal), decentralized finance, and now AI-powered collaboration tools. Dorsey has been a vocal advocate for open protocols, decentralization, and Bitcoin. Buzz aligns with his vision of reducing reliance on centralized platforms.
Block has historically focused on financial services, but Buzz marks a significant expansion into the enterprise software space. The company’s existing infrastructure and talent pool could give Buzz a strong foundation for development and adoption. However, competing with Slack—which is owned by Salesforce and has a massive user base—will require Buzz to offer unique value propositions, such as deeper AI integration and open-source customizability.
Competitive Landscape
Dorsey is not alone in trying to create AI-native alternatives to Slack. Georgios Konstantopoulos, a partner and CTO at Paradigm, recently introduced a similar open-source product called Centaur, which he describes as a “virtual employee” that can operate inside Slack or via an API. Konstantopoulos emphasized that there is “a lot of room for improvement for agents that live in Slack and can do more work than just coding for teams.” In an enterprise setting, self-hosting for security and control is often necessary, and tools like Centaur and Buzz aim to address these needs.
The rise of AI agents has created new opportunities for collaboration software. Traditional chat platforms like Slack were not designed with AI agents in mind, leading to friction when teams try to integrate automated workflows. Buzz solves this by making AI agents first-class citizens in the chat interface. Users can assign tasks to agents, receive updates, and collaborate across multiple AI models. Since Buzz is model-agnostic, teams can use any AI model they prefer, avoiding vendor lock-in.
Implications for the Workplace
For startups that are building AI agents and have not already invested heavily in Slack, Buzz offers a promising alternative. However, the platform itself admits it is in its “early stages,” so migrating established teams may be risky at this point. The open-source nature of Buzz allows early adopters to test and contribute to its development. As the ecosystem around AI agents matures, tools like Buzz could become central to workplace productivity.
The broader trend of AI integration into everyday tools is accelerating. Companies like Microsoft and Google are embedding AI into their office suites, but open-source alternatives like Buzz provide a level of transparency and customization that proprietary tools cannot match. Buzz also aligns with the growing demand for self-sovereign identity and data ownership. By giving teams full control over their infrastructure, Buzz addresses privacy and security concerns that are paramount in enterprise settings.
Dorsey’s announcement on X garnered immediate attention, with many users expressing excitement about a potential Slack alternative that is built for the AI era. However, the success of Buzz will depend on its ability to attract a critical mass of developers and teams. Historical precedent suggests that open-source projects often struggle with adoption and sustainability, but Block’s resources and Dorsey’s influence could tip the scales.
In addition to AI agents, Buzz’s integration with GitHub project management is a key differentiator. Many software teams already use GitHub for code hosting and project tracking. By bringing GitHub workflows into the chat interface, Buzz reduces context switching and streamlines collaboration. This feature could be particularly appealing to engineering teams that want a unified platform for communication and development.
Overall, Buzz represents a bold step into the enterprise collaboration market by an established player. Whether it succeeds or not, it will likely push competitors like Slack and Microsoft Teams to accelerate their AI integration efforts. The era of human-only chat is giving way to hybrid conversations where AI agents actively participate, and Buzz is positioned at the forefront of this shift.
