Viktor, an AI coworker that integrates with Slack and Microsoft Teams, has secured €64.7 million ($75 million) in Series A funding, led by Accel. This significant round follows Viktor's public launch in February 2026 and comes after achieving a €12.9 million ($15 million) revenue run rate within its first 10 weeks. The company plans to use these funds to further develop its AI agents, which operate autonomously for extended periods and can manage projects and recurring tasks.
