Legora said Thursday that it has added a $50 million extension to its previously announced Series D, bringing the total round to $600 million and lifting the legal AI company's post-money valuation to $5.6 billion.

What changed

According to Legora's press release, the extension adds Atlassian and NVentures, NVIDIA's venture arm, alongside new financial investors including Airtree, Barclays, Geodesic, Insight, Liberty Global, and Nikesh Arora. CNBC separately reported that this marks NVIDIA's first disclosed legal-tech investment.

Legora says the company has also crossed $100 million in annual recurring revenue and now serves more than 1,000 organizations across 50-plus markets. In a separate company release, it said that growth came less than 18 months after the general launch of its platform and reflects rising use of AI for multi-step legal workflows rather than one-off research or document review tasks.

Why it matters

This is still a company-reported growth story, so the conservative takeaway is narrower than the valuation headline: investors are backing legal AI vendors that can show real enterprise adoption, not just model demos. Legora says it has grown from 40 to 400 employees over the past year and is now selling into both law firms and in-house legal teams.

The funding also keeps pressure on Harvey, the best-known U.S. rival in the category. But the more durable signal is that corporate investors like NVIDIA and Atlassian now see legal workflow software as a meaningful market for agent-style AI products.
