Viktor, an AI startup that builds a virtual coworker agent embedded inside a company's Slack or Microsoft Teams workspace, raised a $75M Series A led by Accel with participation from Bek Ventures, Kaya VC, Inovo VC, and Tenacity Capital, plus angel investors including Slack cofounders Stewart Butterfield and Cal Henderson, Synthesia CEO Victor Riparbelli, and executives from Google DeepMind, Figma, and ElevenLabs. Just three months after Viktor's public launch in February, the company has reached a $15M annualized revenue run rate with more than 2,000 organizations using the product, with Viktor connecting to systems like Google Drive, Meta Ads, Airtable, Notion, and Shopify to handle tasks like pulling reports, building internal apps, and proposing new workflows. The company competes against Microsoft Copilot and Salesforce's Agentforce in the agentic AI coworker space, with Accel partner Zhenya Loginov pitching the team-focused assistant angle as Viktor's differentiator versus the individual-assistant approach taken by most competitors.
