Viktor, a Warsaw and Munich-based AI startup that develops an AI coworker that lives in Slack and Microsoft Teams and works across the tools companies already use, has raised €64.7 million ($75 million) in Series A funding.
The round was led by Accel, with participation from Bek Ventures, Kaya VC, Inovo VC and Tenacity Capital. Angel investors, including Stewart Butterfield and Cal Henderson, co-founders of Slack; Guillermo Rauch, founder and CEO of Vercel; Victor Riparbelli, co-founder and CEO of Synthesia; Koen Bok and Jorn van Dijk, co-founders of Framer; Alex Bouaziz, co-founder and CEO of Deel; as well as Lenny Rachitsky and Harry Stebbings, participated in the round, along with executives from DeepMind, Figma, and Lovable.
They join existing investors, including Leonis Capital, Oxford Seed Fund, Nat Friedman (former GitHub CEO), Daniel Gross (former Head of AI at Y Combinator/Apple), Charlie Songhurst, Nico Rosberg, and Mati Staniszewski (co-founder of ElevenLabs).
Fryderyk Wiatrowski, CEO and co-founder of Viktor, said, “The next phase of AI is agents that join your company, understand how work gets done, and take responsibility for outcomes. Viktor is designed to be an AI employee – one that can run projects, complete recurring tasks, build tools and help a company move faster. We’re seeing teams treat Viktor like a hire, and that is the shift we want to bring to every company.”
Founded in 2023 by former Meta engineers Fryderyk Wiatrowski and Peter Albert, Viktor positions itself as an AI hire, not a tool. It lives in Slack and Microsoft Teams, integrates with the company’s existing systems, and takes responsibility for outcomes as a colleague would. Companies use Viktor to create reports, dashboards, apps, campaigns, code and recurring automations across their existing business systems.
Viktor states that after joining a company, it studies how the business operates, identifies repetitive and high-leverage work, and proposes projects to the team, be it automating a marketing workflow or rebuilding a broken internal process.
The company states that Viktor is one of the first agents capable of operating autonomously for weeks rather than minutes, maintaining context across thousands of emails, documents, and tools during its work. Any employee can message Viktor as they would a colleague to analyse live data, create a report suitable for a board presentation, research competitors, develop internal tools, or deploy code.
Viktor delivers the completed work across the formats companies already use, including PDFs, spreadsheets, presentations, deployed apps, code commits, and workflow automations. This means teams can move from a Slack or Teams message to a completed report, dashboard, internal tool or automation without switching systems or manually stitching together context.
Viktor was launched publicly in February 2026. Since then, it has reached a €12.9 million ($15 million) revenue run rate within just 10 weeks and is currently used by over 2,000 organisations globally. The company states that small businesses, agencies, ecommerce companies, technology startups and more are using the platform across operations, growth, marketing, finance and engineering.
Most organisations using Viktor integrate over 30 applications into the platform, providing teams with a unified interface for work that was previously distributed across multiple systems.
The company reported that Viktor helped a health and lifestyle group cut €3.8 million ($4.5 million) from a construction project budget; a founder set up the infrastructure for a €862k-per-year ($1 million-per-year) content agency with no staff in just nine days; and a landscaping business implemented 63 automations across operations, HR, collections, and email management within two weeks.
Zhenya Loginov, Partner at Accel, said, “Viktor finally merges the worlds of collaboration and AI that have previously remained separate. We see an opportunity for Viktor to remove the barriers of AI adoption in the enterprise by being embedded where teams already work and connected with all the tools employees have access to.”
With this funding, the company plans to accelerate Viktor’s global rollout and expand product capabilities. It is also planning to open an office in New York.
