Barcelona-based Factorial raised $150m Series D at a $2.5bn valuation, becoming one of Europe's most valuable AI scaleups. The round, backed by General Catalyst and Atomico, marks a significant vote of confidence in the company's transformation from HR software provider to AI-powered workforce platform serving over 16k businesses globally.

Factorial has rebuilt its SaaS platform around AI agents capable of handling HR, finance, and IT workflows. CEO Jordi Romero emphasized the strategic shift: "Ten years ago we built Factorial as a SaaS company. Today we are an AI-first company." The company's Factorial One product uses a streamlined approach with fewer specialized AI agents representing both employers and employees.

Beyond the equity financing, General Catalyst committed up to $540m through its Customer Value Fund, bringing total available capital to more than $700m. Factorial will direct a significant portion toward Germany, opening a Munich office while expanding in France, Italy, and Portugal. The substantial funding underscores investors' belief in Factorial's AI-first approach to enterprise software.
