Viktor

Viktor is an AI coworker that installs into Slack or Microsoft Teams and runs work end to end, rather than just answering questions in a chat window. Built by a Warsaw and Munich based team, it connects to more than 3,000 business tools and delivers finished outputs like PDFs, spreadsheets, web apps, and code , then schedules recurring tasks and proposes automations the user did not think to ask for . The pitch is aimed at the operators who never get their own ops or data team, from plumbers and agencies up to Fortune 500 departments stuck doing repetitive status updates, report pulls, and data entry. The launch matters because Viktor is announcing a $75M Series A. The round was led by Accel with participation from Bek Ventures, Kaya VC, Inovo VC, and Tenacity Capital , and notably angel investors include Slack cofounders Stewart Butterfield and Cal Henderson backing an AI agent that lives inside the product they built . The capital is earmarked for global rollout and broader product capabilities, putting Viktor in direct competition with the growing field of agentic copilots embedded in collaboration suites. The company comes from Zeta Labs, the team behind the Jace AI email assistant. Viktor was founded in 2023 and is led by Fryderyk Wiatrowski (CEO) and Peter Albert (CTO) , both ex-Meta engineers who, per Wiatrowski, concluded that the email inbox was not the optimal surface for an AI agent and shifted the work into Slack and Teams . For founders and operators evaluating where to place agent bets, Viktor is worth a look as a wedge into the chat surface where most internal work already happens.
