Viktor

Viktor builds an AI coworker that lives inside Slack and Microsoft Teams and connects to more than 3,000 workplace tools. Work is assigned to it in plain language; it decomposes the request into tasks, executes them across the connected systems and returns finished artefacts such as reports, spreadsheets, dashboards or code. Founded in 2023 by Fryderyk Wiatrowski and Peter Albert, who met at Meta, it is headquartered in Warsaw with a Munich office, launched publicly in February 2026 and raised a $75m Series A led by Accel in May 2026 — the largest ever raised by a Polish-founded company.
