Viktor secures $75 million from Accel to integrate an AI coworker into Slack and Teams.

      The ex-Meta engineering team based in Warsaw and Munich achieved $15 million in annual recurring revenue within just ten weeks. Their angel investor list features notable names from the European and US software industries.

      Viktor, the AI agent company founded by former Meta engineers Peter Albert and Fryderyk Wiatrowski, has secured $75 million in a Series A funding round led by Accel. The round also included participation from Bek Ventures, Kaya VC, Inovo VC, and Tenacity Capital, along with an extensive list of angel investors such as Slack co-founders Stewart Butterfield and Cal Henderson, Vercel CEO Guillermo Rauch, Deel CEO Alex Bouaziz, ElevenLabs CEO Mati Staniszewski, Framer founder Koen Bok, Instacart co-founder Max Mullen, Sana founder Joel Hellermark, along with various investors like 20VC’s Harry Stebbings, Lenny Rachitsky, Shaan Puri, Charlie Songhurst, Daniel Gross, and Nat Friedman.

      The rapid customer growth is what makes this funding round noteworthy. According to the founders, Viktor reached $15 million in annual recurring revenue in around ten weeks. The company claims that over 12,000 teams have installed Viktor on Slack and Microsoft Teams. This growth trajectory attracted Accel to invest in this Series A, just eighteen months after the company's product was launched. Furthermore, it appears to outpace any similar enterprise software distribution metrics in the recent Slack marketplace ecosystem.

      Viktor operates within a customer’s existing Slack or Microsoft Teams environment, connecting to more than 3,000 SaaS tools to carry out multi-step workflows such as reporting, drafting, scheduling, data entry, status updates, and providing overnight instructions via phone. It presents itself as a team member rather than a personal assistant, distinguishing itself from other AI solutions like ChatGPT, OpenAI’s OpenClaw, Claude’s integration with Slack, and Tasklet.

      Accel partner Zhenya Loginov will join Viktor's board. The firm’s portfolio note categorizes Viktor as part of the ‘modern workplace’ AI segment, a market primarily dominated by frontier-model labs offering APIs and downstream platforms that resell them. Albert (CTO) and Wiatrowski (CEO) originally met at Meta, and their six-member engineering team has backgrounds from Meta, Google, and Oxford. The base of operations split between Warsaw and Munich establishes Viktor as a European company reaching out to two American communication platforms, which explains the presence of investors like Butterfield and Henderson, who operate within the Slack marketplace, along with Bok, Staniszewski, Rauch, and Hellermark, who are European founders against whom Viktor is measuring its growth.

      Customer feedback serves to emphasize growth metrics that the company has not disclosed. Justin Hibbert, CEO of Highgarden Holdings, mentions that Viktor helped reduce their budget from $12.5 million to $7.2 million, while Nico Torres from Authority Makers attributes $133,752 a year in new recurring revenue within the first thirty days to Viktor. Jacob Aldridge from Como Business Coaching calls it “the cheapest employee I’ve ever hired.” The marketing strategy positions Viktor specifically against ChatGPT, betting that such a comparison resonates with potential buyers’ pre-existing mental frameworks.

      The broader context of the market plays a crucial role in understanding the long-term significance of this funding round. Anthropic released ten financial-services agent templates within Claude earlier this month, targeting Microsoft 365 for distribution. Companies like Google, OpenAI, and Salesforce have also been promoting various versions of the agent-in-the-workflow approach.

      Viktor argues that the agent that ultimately succeeds in the workplace environment will be the one that seamlessly integrates into the team’s established chat platform with minimal installation friction, rather than the one with the superior model quality.

      The forthcoming year will be critical in determining if the company can sustain its growth rate against established foundation-model-lab competitors who are also working toward the same integration. Wilson Sonsini acted as legal advisor for the Series A. Details regarding post-money valuation, revenue exceeding the $15 million ARR figure, and plans for expanding the Warsaw-Munich workforce have not been shared.

      This Series A funding will reportedly be used to further develop engineering efforts, increase integrations to meet the target of 3,000 tools, and scale up in the enterprise segment.
