Legora raises $550 million Series E at $8.8 billion valuation to accelerate growth.

Round led by Atreides with established long-term and strategic investors. Capital funds US and international expansion and further investment in the Legora aOS.

NEW YORK & STOCKHOLM, October 21, 2026 – Legora, the agentic operating system for legal professionals, today announced it has raised a $550 million Series E at an $8.8 billion post-money valuation. The round was led by Atreides Management, with participation from new investors, including Baron Capital, Capital Group, Fidelity Management & Research Company, Glade Brook Capital Partners, and J.P Morgan. Every major existing investor, including Accel, Benchmark, Bessemer Venture Partners, General Catalyst, ICONIQ, Insight Venture Partners, Menlo Ventures, Redpoint Ventures, Salesforce Ventures, and Sands Capital, is also participating.

Legora built the round around investors with a long time horizon. It brings together established long-term holders with strategic investors, institutions that work with law firms and in-house legal teams every day and have a close view of where legal work is heading.

The round follows a period of rapid growth. Legora went from $1 million to $100 million in ARR in less than 18 months, faster than any other enterprise software company selling through a direct sales team, and the next $100 million took less than six months. ARR now stands at more than $200 million. The new valuation compares with $5.6 billion at the company's previous round.

Legal teams are moving beyond AI assistants toward agents that carry out multi-step work, and Legora's offering and geographic footprint are expanding to meet that shift. In-house legal teams, only a small fraction of Legora's customer base a year ago, made up more than 40% of new customers in the third quarter. In the United States, now Legora's largest market by revenue, more than half of the AmLaw 50 are customers, and Legora opened its first US office only in spring 2025.

"The opportunity in legal is enormous and we are still early. AI is changing the role of the lawyer, with more time for judgment and advice, and it is reshaping how law firms and in-house legal teams are organized and how their work gets done. We intend to lead that shift in the US and globally. We chose investors who share our long-term view and know what it takes to build a lasting company. They are the right partners for the years ahead," said Max Junestrand, CEO and Co-Founder of Legora.

The capital will support continued expansion in North America, where Legora has offices in New York, Denver, Chicago, Houston, San Francisco, Toronto and Mexico City, as well as in its markets across Europe and Asia-Pacific. It will also deepen investment in the Legora aOS, the agentic operating system that lawyers and their agents work in; bringing new products like agentic in-take, horizon scanning and legal research to life.

"Legal is a sophisticated market with demanding buyers, and the bar for software is high. Legora has become the platform that law firms and in-house legal teams adopt and then expand across their organizations, and it has done so while growing at remarkable speed. Legora has also built a sustainable business along the way, with the discipline to scale fast and stay efficient. We are excited to support the team as Legora enters its next stage of growth in the US and globally," said Gavin Baker, Managing Partner and CIO at Atreides.

Legora was founded in 2023, and launched its platform in October 2024. It now has more than 1,000 employees across 18 offices and is used by more than 140,000 legal professionals at more than 2,400 leading law firms and in-house legal teams across over 80 markets.

"Growth only counts if the business underneath it holds up. We have passed $200 million in ARR, and we want every dollar of it to be a durable one. That means healthy gross margins, high retention, and a cost structure that gets stronger as we scale. This round lets us keep building that way," said David Eckstein, CFO at Legora.
