Legora raised a $550 million Series E at an $8.8 billion post-money valuation on October 21, 2026, led by Atreides Management. Its previous round valued it at $5.6 billion. The legal AI company says annual recurring revenue now stands at more than $200 million, and that the second $100 million took less than six months.
Legora calls itself “the agentic operating system for legal professionals.” The money goes to expansion in North America, Europe and Asia-Pacific, and to new agent products: agentic intake, horizon scanning and legal research. Here is what the announcement says, number by number.
Legora raised a $550 million Series E at an $8.8 billion post-money valuation on October 21, 2026, led by Atreides Management.
Its annual recurring revenue passed $200 million; the first $100 million took under 18 months and the second under six.
In-house legal teams made up more than 40% of new customers in the third quarter, and more than half of the AmLaw 50 are customers.
The money funds expansion across North America, Europe and Asia-Pacific; the US is already its largest market by revenue.
Legora plans agentic intake, horizon scanning and legal research inside the Legora aOS.
§ 01The round
| Item | Detail |
|---|---|
| Amount | $550 million |
| Valuation | $8.8 billion post-money |
| Previous valuation | $5.6 billion |
| Lead | Atreides Management |
| New investors | Baron Capital, Capital Group, Fidelity, Glade Brook, J.P. Morgan |
| Existing investors | Accel, Benchmark, Bessemer, General Catalyst, ICONIQ, Insight, Menlo, Redpoint, Salesforce Ventures, Sands Capital |
The announcement says every major existing investor took part. Legora’s own framing of the investor list is “investors with a long time horizon”, including institutions that work with law firms and in-house teams every day.
§ 02The growth numbers
Legora was founded in 2023 and launched its platform in October 2024. Its disclosed figures:
| Metric | Figure |
|---|---|
| ARR | More than $200 million |
| $1M to $100M ARR | Less than 18 months |
| $100M to $200M ARR | Less than six months |
| Legal professionals using it | More than 140,000 |
| Law firms and in-house teams | More than 2,400 |
| Markets | More than 80 |
| Employees | More than 1,000, across 18 offices |
| In-house share of new customers, Q3 | More than 40% |
Two figures carry the story. The United States is now Legora’s largest market by revenue, and more than half of the AmLaw 50 are customers, from a company that opened its first US office in spring 2025. And in-house legal teams, “only a small fraction of Legora’s customer base a year ago”, were more than 40% of new customers in the third quarter.
Legora also says its first $100 million of ARR came faster than at “any other enterprise software company selling through a direct sales team.” That is the company’s own claim; it does not publish the comparison set.
§ 03What the money is for
North American offices in New York, Denver, Chicago, Houston, San Francisco, Toronto and Mexico City; continued growth in Europe and Asia-Pacific; and the Legora aOS, which it describes as the system “that lawyers and their agents work in.”
The three people quoted set the tone. CEO Max Junestrand: “The opportunity in legal is enormous and we are still early.” Atreides CIO Gavin Baker: “Legal is a sophisticated market with demanding buyers, and the bar for software is high.” CFO David Eckstein: “Growth only counts if the business underneath it holds up.”
§ 04What it says about legal AI
Legora’s announcement describes legal teams moving from AI assistants toward agents that carry out multi-step work. The same month, OpenAI was selling Astra for Law and Z.ai shipped GLM-Legal: the model labs and the application companies are now competing for the same law-firm budget, and the in-house number suggests the buyer base is widening beyond the big firms.
For smaller legal teams the practical question is less which platform raised the most and more which routine work an agent can take off a person’s desk: intake, deadline tracking, first-pass research and document summaries, with a lawyer reviewing every output.
