Most teams aren’t looking for another standalone AI tool that they have to log into separately. Viktor, an AI coworker startup founded in Warsaw and Munich, is addressing that directly. The product lives inside Slack and Microsoft Teams, connects to over 3,000 workplace tools, and handles actual work tasks without requiring teams to change how they operate. Viktor launched publicly in February 2026 and reached a €12.9 million ($15 million) revenue run rate within just 10 weeks. That growth pace helped the company close a significant funding round this month.
The Funding and Investors:
Viktor raised €64.7 million ($75 million) in a Series A round led by Accel, with participation from Bek Ventures, Kaya VC, Inovo VC, and Tenacity Capital. The angel investor list is notable on its own. Stewart Butterfield and Cal Henderson, co-founders of Slack, joined the round alongside Guillermo Rauch of Vercel, Alex Bouaziz of Deel, Victor Riparbelli of Synthesia, and executives from DeepMind, Figma, and Lovable. When the co-founders of the platform your product runs on are personally writing checks, that’s a signal worth paying attention to.
The team behind Viktor includes six engineers from Meta, Google, and Oxford, built over three years in Warsaw and Munich. The founders, Fryderyk Wiatrowski and Peter Albert, spent time experimenting with AI agents before landing on the current product direction.
What Viktor Actually Does:
Viktor works as an AI coworker within Slack or Microsoft Teams. You message it the way you’d message a colleague, and it takes action across the tools your business already uses. It connects to more than 3,000 workplace tools, including Google Drive, Meta Ads, Airtable, and Notion, and can be used by anyone in a company through Slack or Teams messages.
Most organisations using Viktor integrate over 30 applications into the platform, giving teams a unified interface for work that was previously spread across multiple systems. This is the practical draw for operators: fewer context switches and actual execution rather than just answers.
Real Results From Real Teams:
The customer outcomes Viktor has reported are specific and varied across business types. Viktor helped a health and lifestyle group cut €3.8 million ($4.5 million) from a construction project budget. A founder built the infrastructure for a €862k-per-year content agency with no staff in nine days. A landscaping business implemented 63 automations across operations, HR, collections, and email management within two weeks.
These aren’t all enterprise use cases. Small businesses, agencies, e-commerce companies, technology startups, and larger organisations are all using the platform across operations, growth, marketing, finance, and engineering. Viktor’s positioning is deliberately broad, which aligns with how the founders framed the funding announcement: the product is designed for any team, not a specific company size or industry.
The Competitive Picture:
Viktor operates in a market where large incumbents are building similar capabilities. The startup competes with Microsoft, which is weaving Copilot into Teams and the Office suite, and with Salesforce’s Agentforce product, which lets companies build and deploy AI agents inside Slack on top of Salesforce data. Viktor’s response to that context is its integration breadth and its positioning as a neutral layer that sits across tools regardless of vendor.
For founders and operators exploring agentic workspace automation, Viktor’s approach to the Slack AI agent category is worth understanding. It’s not pitching a replacement for your existing stack but rather a layer that connects and acts across it. The 2,000-plus organisations using it within 10 weeks of launch suggest that positioning is resonating.
Viktor plans to scale enterprise adoption by improving governance, integrations, and operational workflows needed for larger organisations, while also continuing to expand the agent’s capabilities across a wider range of workplace processes. For teams already inside Slack or Teams, the friction to try it is low. The product connects where the work already happens, and the company now has $75 million to keep building from there.
