Rob Seaman: Slack as the multiplayer runtime for AI agents
Rob Seaman, CEO and GM of Slack at Salesforce, traces Slack's channel-based-messaging roots and why it made sense for Salesforce, positioning Slack as the interface where AI agents land. He shares that Slack passed a billion messages a day (about 2x Twitter), explains the product principles "be a good host" and "don't make me think," and describes Slack as the open, "multiplayer runtime" of the AI stack. He also details the shipping culture: 4x PR throughput via agentic coding, roughly 70–80% AI-written code, teams collapsing from 40 to 10, and "jazz band" team composition.
