Mio is a Slack-native AI coworker positioned as 'the Chief of Staff that already knows your company.' Installed directly into a Slack workspace in under 30 seconds, it can be @mentioned in any channel to answer questions about company context, prepare meeting briefs, triage inboxes, draft reports, update CRMs, write code, onboard new hires, and automate recurring workflows. It supports 3,000+ integrations and claims to save teams an average of 8 hours per week. The company pivoted from an original 'context as a service' developer SDK product (mid-2025) to the current Slack-native AI coworker by early 2026.
