A $50m extension has pushed Legora's Series D to $600m in total equity, valuing the Stockholm-based legal AI company at $5.6bn post-money.

Nvidia's venture arm NVentures and Atlassian joined the round as corporate investors. Adams Street Partners, Airtree, Barclays, Geodesic Capital, Insight Partners, Liberty Global, and Nikesh Arora — the Palo Alto Networks CEO who invested in a personal capacity — came in as financial backers.

The extension follows the $550m tranche Legora closed in March. That round already made the company one of Europe's largest legal tech fundraises.

Legora builds an agentic AI platform for corporate legal teams. The company recently crossed $100m in annual recurring revenue, a milestone it reached less than two years after launch. It now counts more than 1,000 enterprise customers and has grown from 40 to 400 employees in the past twelve months.

"Foundation models are improving rapidly, but the real breakthrough is in how they're applied, where AI doesn't just assist, but executes autonomously with the right level of human oversight," said Max Junestrand, CEO and cofounder, in a statement.

Two acquisitions in two months

The fresh capital follows a rapid buy-and-build push. In March, Legora acquired Canadian startup Walter AI to expand its agentic platform into the Canadian legal market. Earlier in April, it picked up Qura, a Stockholm-based company focused on AI-native legal research.

Junestrand told Sifted the acquisitions are partly a talent play. "We always hire the best people on the planet and these happen to be in other companies building in either adjacent or different verticals," he said.

The strategy mirrors a pattern seen across fast-scaling AI companies: acqui-hiring specialized teams rather than competing for individual engineers in a tight labor market.

Legora competes in a legal AI segment that includes Harvey, EvenUp, and Spellbook, though its European base and enterprise focus give it a different customer profile. The company's ARR growth — from near-zero to $100m in roughly two years — puts it in the same bracket as some of the fastest-scaling vertical AI startups globally.

NVentures' participation signals Nvidia's continued interest in application-layer AI companies, not just infrastructure. Atlassian's investment suggests potential integration with its collaboration tools, though neither company has confirmed product plans.

Junestrand is scheduled to speak at the Sifted Summit in London on September 30.
