Block is taking on slack
Jack Dorsey (@jack) said in an announcement on X on July 21st that Block is launching Buzz, an open-source workspace designed to put employees, AI agents, conversations and software repositories behind one identity system.
Dorsey, Block's cofounder and Block Head, is pitching Buzz as a way to reduce Block's dependence on Slack and GitHub. The move takes his preference for open protocols into the daily machinery of software development, where teams typically spread discussions, source code, automated workflows and agent activity across several vendors.
Buzz also fits the operating model Dorsey has been building inside Block. In an essay with Sequoia Capital's Roelof Botha, Dorsey argued that AI should change how organizations coordinate rather than serve only as a productivity add-on. Buzz supplies an infrastructure layer for that thesis: Block's public repository documents a separate internal build configured for Block's relay and agent provider.
Slack is proving to be extremely valuable in the agent world and is perhaps salesforce’s most interesting property right now. A few people have tried to take on its dominance (including superconductor.com, check them out they’re cool) but thus far its been extremely hard to deal with the staying power of slack connect, which gives slack social-media like moats (coordination problems remain impossible to solve).
Curious to see how this goes
