Mio, an AI agent designed to operate as a persistent team member inside Slack, has raised $2.2 million in pre-seed funding. The round was backed by Casey Caruso and Thomas Crow. Financial terms beyond the total raise were not disclosed.
Mio is built to function as a working colleague rather than a conversational assistant — learning how a specific company operates, connecting to the tools a team already uses through more than 3,000 integrations, and executing work autonomously across engineering, product, customer success, and growth functions. Users interact with it by tagging it directly in Slack with @mio. The company reported that Mio returned more than 130 hours to its own team in a single week during early deployment.
The product is positioned at the intersection of two trends gaining traction in enterprise software: the move from AI assistants that answer questions to AI agents that complete tasks, and the consolidation of work coordination inside messaging platforms like Slack rather than standalone productivity tools. By living inside Slack rather than requiring a separate interface, Mio reduces the context-switching cost of working with an AI system and embeds it into existing team workflows without requiring behavioral change.

“Software can now do the work. To me, that doesn’t mean replacing team members. It means giving them back time to focus on what they do best.”
