Mio Raises $2.2M for AI Colleague Inside Slack

Jan de Vries · 2026-07-15

Mio, a Paris-based startup, just stepped out of stealth mode with a big announcement. They've raised $2.2 million in pre-Seed funding to build an AI colleague that lives right inside Slack. No more jumping between apps or remembering to open a chatbot—Mio wants to be the silent partner that just gets work done. The round was co-led by Fabric.vc and Topology.vc. Mio plans to use the cash to grow its engineering team, speed up product development, and expand its customer base across Europe and the United States. This is a clear signal that the AI workspace is shifting from passive tools to active teammates. ### What Makes Mio Different? Mio isn't just another chatbot. According to founder and CEO Arthaud Mesnard, "We don't think the future of AI at work is another app people have to open. The best colleague already understands what's happening, knows how your company works, and steps in before you have to ask." Launched in 2025 by Mesnard, a repeat entrepreneur, Mio integrates directly into team workflows. It handles repetitive tasks, keeps information fresh, and pushes work forward without needing a nudge. Unlike standalone AI assistants, Mio learns how your company operates. It connects to tools you already use—like Google Workspace, Notion, Linear, HubSpot, and GitHub—and gets smarter over time. Because Mio is model-agnostic, it picks the best AI model for each task, so you aren't locked into one provider. ### How Mio Stacks Up Against ChatGPT or Claude for Slack Most AI chatbots answer from public info. Mio is different. It's grounded in your company's actual data: messages, documents, tickets, and calendars. It doesn't just suggest—it takes action across your connected tools. Think of it as a team member who knows your context and can execute tasks on your behalf. Here's what Mio can do for you: - Morning briefs to start your day on track - Meeting recaps so nothing gets lost - CRM updates that keep your sales pipeline accurate - Customer follow-ups that never slip through the cracks - Reporting and analysis that saves hours - Engineering tasks like code reviews or bug tracking ### Privacy and Security First Mio takes data security seriously. Its access is limited to channels and DMs it's invited to. Optional integrations only activate if you choose to connect them. Mio explicitly states it does not train AI models using customer data. The platform is GDPR compliant and runs on Google Cloud Platform in Europe, with encryption at rest and in transit. All integration credentials are encrypted too. ### The Shift from Chat to Action "The launch comes as AI shifts from answering questions to getting work done," Mio noted in its press release. "While the first wave of AI focused on chat interfaces, a new generation of agents is beginning to operate directly inside the tools teams already use. Mio believes Slack is becoming the natural home for that shift." Over 100 companies, from early startups to Series B scale-ups, are already using Mio daily. Early customers report saving more than a full workday each week—averaging 8.2 hours. That's real productivity gain, not just hype. ### The Bottom Line Mio is betting that the future of work isn't more apps—it's smarter integration. By embedding an AI colleague into Slack, they're making it easier for teams to get things done without breaking their flow. With $2.2 million in funding and a growing customer base, Mio is poised to make a real impact.
