Shopify's River — the agent you can only use in public
Tobi Lutke shares how Shopify built an AI agent called River that helps employees work and learn together — publicly, on Slack. The detail that matters: River isn’t private. Employees can only use it in the open, which means every query, every answer, every correction plays out where colleagues can watch. What looks like a productivity tool is actually a cultural one. The agent becomes a teaching workshop — ambient, always on, free to observe.
