Nvidia and Atlassian back Legora, valuing the legal AI startup at $5.6 billion

Legora, a Swedish AI startup for lawyers, has added $50 million to its Series D, bringing the round to $600 million at a $5.6 billion valuation. Nvidia and Atlassian joined the extension, and it marks Nvidia's first investment in legal tech.

The round and the valuation

The current extension follows the first Series D tranche in March, when Legora raised $550 million at a valuation of about $5.55 billion. With the extra $50 million, the valuation barely moved and settled at $5.6 billion. Since its founding in Stockholm in 2023 by Max Junestrand and Sigge Labor, originally under the name Leya, the company has raised $866 million in total. For European B2B software, that pace of fundraising is rare in itself, and rarer still in legal AI.

But the size of the round is not the only thing attracting investors. Legora says it passed $100 million in annual recurring revenue in just 18 months, one of the fastest ARR trajectories in European software history. The platform helps lawyers research case law and regulations, draft documents, check wording and coordinate multi-step workflows. The service is built on large language models, and the company names Claude as its base model.

Why Nvidia came in

NVentures' entry looks like an important signal, but not because Nvidia suddenly decided to bet on the legal market specifically. More likely, the chip giant saw in Legora a platform with heavy agentic workloads: legal work requires processing huge volumes of unstructured text, weighing arguments and precedents, accounting for different jurisdictions, and keeping client data confidential. For an infrastructure investor, that is an almost ideal use case for inference workloads.

"From passive assistance to an agentic operating system for legal work."

That is how CEO Max Junestrand describes the product's shift. When a user no longer just submits a single query but launches chains of research, drafting, review and approval, the compute load per session rises sharply.

Beyond money, Nvidia usually gives portfolio companies access to GPUs, engineering expertise and help optimizing model runs on its hardware. For Legora, that may be no less valuable than the check itself.

Atlassian's participation follows a different logic. The company owns Jira, Confluence and other enterprise collaboration tools, so its interest in Legora can be read as a bet on integrating agentic legal workflows into companies' shared processes. If that plan works out, legal AI will stop being a standalone assistant for the legal department and become part of a broader system for managing knowledge, tasks, approvals and internal documentation.

Growth and expansion

Over the past year and a half, Legora has scaled on nearly every key metric at once. The company did not grow along a single axis, such as revenue or headcount alone, but across customer base, geography, hiring and capital simultaneously. That combination usually shows a product has moved beyond pilots and become a working platform for large legal teams:

• ARR grew from about $1 million to more than $100 million
• Headcount rose from 40 to 400 employees
• The customer base expanded from 200 to more than 1,000 organizations
• The product is now used in 50 markets
• Total funding raised reached $866 million

Legora's customers include White & Case, Linklaters, Cleary Gottlieb, Barclays and large in-house legal departments. According to the company, lawyers save an average of 4.3 non-billable hours per person per week, and 42% of firms report that the platform helped them win new business. That detail matters: the market is ready to pay not just for automating routine tasks but for tools that directly affect team workload and practice revenue.

The main focus for the new money is the US. Legora opened a New York office in March 2025, then added Denver, and now plans Houston and Chicago, aiming to exceed 300 US employees by the end of 2026. In parallel, the company is accelerating its product through M&A: in March it bought the Canadian legal AI startup Walter, and in April the Swedish project Qura, whose precise-search technology strengthens the platform's research layer. All of this should help Legora keep pace in its race with Harvey and more general-purpose AI platforms.

What this means

Legora's round shows that legal AI is quickly turning from a narrow category of assistants into an infrastructure market with high stakes. Nvidia's entry confirms that the value here lies not only in automating lawyers' work but also in building stable, compute-hungry agentic workflows.

The next question for Legora is whether it can turn capital and growth speed into long-term leadership.
