Jack Dorsey Launches Buzz to Challenge Slack — and It Puts AI Agents in Your Team Chat

Jack Dorsey Is Taking On Slack With Buzz — A Group Chat Platform Built for Humans and AI Agents

Jack Dorsey is not done disrupting industries. The co-founder of Twitter and Square has turned his attention to the workplace collaboration market, launching a new group chat platform called Buzz that puts human team members and their AI agents in the same conversation thread. According to Amanda Silberling at TechCrunch AI, Buzz is a direct challenge to Slack and positions itself as the communication layer for a workplace where AI is no longer a background tool — it is a participant.

This is a significant moment. Not because another chat app has entered the market, but because of what Buzz represents: an acknowledgment that the way teams communicate is changing at a structural level, and that the tools we use need to catch up.

What Buzz Actually Does

The core premise of Buzz, as reported by TechCrunch, is straightforward but consequential. Rather than treating AI as a bolt-on integration — a bot you summon with a slash command or a plugin that lives in a sidebar — Buzz places AI agents directly inside the conversation alongside human team members. Humans and AI share the same channels, the same threads, the same context.

That design philosophy matters. It means an AI agent is not waiting to be called upon. It is present, aware of the conversation, and presumably able to act on relevant information in real time. Think less "ask the AI" and more "the AI is already on the team."

Dorsey's decision to build in this space also signals something about where he sees the near-term future of work. This is not a moonshot bet on AGI. It is a practical, product-level wager that the teams using workplace software in the next 12 to 24 months will increasingly want their AI tools to be embedded in their daily communication — not siloed in separate dashboards.

Why This Challenges Slack More Than It Might Appear

Slack is not standing still. Salesforce has invested heavily in bringing AI into the Slack ecosystem, and the platform already supports various AI-powered workflows. But there is a meaningful difference between a platform that has added AI features and a platform that was designed from the ground up with AI agents as first-class participants.

Buzz has the advantage of starting fresh. No legacy architecture. No backwards compatibility concerns. No existing enterprise contracts that create inertia. Dorsey can build the interaction model exactly as he wants it without compromise.

For Slack and Microsoft Teams, this is the classic innovator's dilemma problem. Incumbents rarely lose on features — they lose when a new entrant reframes what the product is fundamentally supposed to do. Buzz is attempting that reframe: workplace chat is no longer just a human-to-human communication layer. It is a human-and-AI collaboration layer.

What This Means for SMBs and Growing Teams

For small and mid-sized businesses, the arrival of platforms like Buzz raises a practical question worth asking now rather than later: how integrated are your AI tools into how your team actually communicates and works?

Most SMBs currently operate with a patchwork approach. There is a chat tool. There are AI tools. There are project management tools. They are loosely connected at best and completely separate at worst. The result is that AI assistance happens in isolated moments rather than as a continuous, embedded part of how work flows through the organization.

The direction Dorsey is betting on — AI agents participating directly in team communication — is the direction the broader industry is moving. Even if Buzz does not become the dominant platform, its existence accelerates the expectation that AI should be woven into collaboration tools at a deeper level.

For business owners and operations leaders, this is the time to audit how your team interacts with AI today. Are people switching contexts to use AI tools? Are insights from AI making it back into team discussions in a useful way? Is your current communication platform limiting what AI can do for your team?

Platforms like WRRK.ai are already helping business teams bring AI-powered workflows and automation into daily operations without requiring a full infrastructure overhaul. As the market moves toward more integrated human-AI collaboration, tools that bridge your current setup with modern AI capabilities become increasingly valuable.

The Bottom Line

Jack Dorsey entering the workplace chat market with an AI-native product is not just a competitive move against Slack. It is a statement about where business communication is heading. The question for every team leader is whether their current tools are built for the workplace that exists now, or the one that is rapidly taking shape.

Frequently Asked Questions

What is Buzz and how is it different from Slack?

Buzz is a new workplace group chat platform launched by Jack Dorsey that is designed to include AI agents as active participants in team conversations, not just as add-on integrations. Unlike Slack, which has added AI features to an existing platform, Buzz was built from the ground up with the premise that humans and AI agents communicate in the same threads and channels.

Will AI agents replace human team members in workplace chat tools?

No. The model Buzz represents is collaborative, not substitutional. AI agents are positioned as participants that can contribute to conversations, surface information, and take action — but alongside human team members, not instead of them. The goal is to reduce friction between where communication happens and where AI assistance is available.

Should small businesses switch to AI-native collaboration platforms now?

Not necessarily immediately, but the trend is worth paying attention to. The more important step for most SMBs right now is assessing how well their existing tools support AI-assisted workflows. If your team is constantly switching between a chat tool and separate AI tools, that context-switching has a real cost. Evaluating more integrated solutions — whether that is a new platform or a bridge tool — is a reasonable next step.
