Salesforce.com IncBuzz is a direct rival to Slack, which Salesforce owns, and the article notes the launch could pressure Salesforce.
Jack Dorsey has launched Buzz, a new open-source group chat platform built by Block Inc. that aims to compete with Slack and GitHub by merging human and AI agent conversations into one workspace. The platform is model-agnostic, decentralized, and available on macOS, Windows, and Linux. The launch could pressure Salesforce, which acquired Slack for $27.7 billion in 2021, and Microsoft, which bought GitHub for $7.5 billion in 2018. Salesforce shares fell 3.6% to $163.90 on Wednesday and are down 35.4% year-to-date in 2026, with KeyBanc analyst Jackson Ader recently downgrading the stock to Sector Weight citing limited growth signs.
