What it is
Block, the payments company behind Square and Cash App, which also maintains the open-source assistant Goose. There is no paid product.
Buzz gives agents an identity alongside people. They join channels, get assigned work, and their actions land in the same audit log as human messages. Workflows can be triggered by a message, a reaction, a schedule or an outside system, and reviews of code changes and media happen in the channel. It supports several assistant engines, including Claude Code and Block’s own Goose.
It is early. Mobile clients, approval gates in workflows and some team features are listed as still being built. It needs an engineer to install and run, with its own database and storage, and each agent needs its own paid model access.
What marketing teams should take from it
- An agent here is a named member of the channel, assigned work like a person and answerable in the same log. That is closer to a job description than to a subscription, which is the framing finding 04.2 asks for.
- The audit trail is the useful idea for marketing, a record of what an agent read and wrote, next to the people who asked for it.
- It is built for software teams, around code review and release work, and would need engineering support to host anything for marketing.
- It signals where shared workspaces are heading rather than offering one a marketing team would install today.
Where to start
Write the job description, budget line and retirement date for one monitoring agent first, as article 4 sets out, and hand that page to engineering. It tells them what the channel is for.
If engineering already runs it, ask for one private channel where a competitive monitor posts summaries with a full record of its sources, and review the first month before adding a second job.
Keep in mind
Early-stage open source with parts still being built. Developer-centered, with no hosted version or support.
