Legal AI company Legora has raised $550 million in a Series E funding round at an $8.8 billion post-money valuation, giving the fast-growing technology provider substantial new capital as law firms and in-house legal teams increase their investment in artificial intelligence.
The round was led by Atreides Management, with new investors including Baron Capital, Capital Group, Fidelity Management & Research Company, Glade Brook Capital Partners and J.P. Morgan. Existing investors including Accel, Benchmark, Bessemer Venture Partners, General Catalyst, ICONIQ, Insight Venture Partners, Menlo Ventures, Redpoint Ventures, Salesforce Ventures and Sands Capital also participated.
Legora said the funding will support expansion across North America, Europe and Asia-Pacific while allowing it to invest further in Legora aOS, its agentic operating system for legal professionals. Planned developments include products covering legal research, horizon scanning and agentic intake.
The scale of the funding reflects the rapid growth of Legora and increasing investment in artificial intelligence across professional legal services. The company says annual recurring revenue rose from $1 million to $100 million in less than 18 months, with the next $100 million added in less than six months. ARR now stands at more than $200 million.
Legora’s previous funding round valued the company at $5.6 billion, making the latest $8.8 billion valuation another substantial increase as investors seek exposure to the expanding legal AI market.
Growth is increasingly being driven by both law firms and corporate legal departments. In-house teams accounted for more than 40% of Legora’s new customers during the third quarter, despite representing only a small proportion of its customer base a year earlier.
The United States has meanwhile become Legora’s largest market by revenue. More than half of the Am Law 50 now use its technology, according to the company, despite Legora opening its first US office only in spring 2025. Its North American footprint now includes offices in New York, Denver, Chicago, Houston, San Francisco, Toronto and Mexico City.
Founded in 2023 and launched commercially in October 2024, Legora now employs more than 1,000 people across 18 offices. The company says more than 140,000 legal professionals use its software across more than 2,400 law firms and in-house legal teams in over 80 markets.
The size of the investment is another indication that AI is moving beyond experimental deployment and becoming part of the technology infrastructure supporting legal work. The increasing focus on agentic systems capable of performing multi-stage tasks also raises strategic questions for law firms around workflows, staffing, supervision and the division of work between lawyers and technology.
The growth of Legora’s in-house customer base is particularly significant. Corporate legal departments becoming major purchasers of the same AI platforms used by external counsel could influence how work is allocated between firms and clients, while increasing expectations around efficiency and technology-enabled service delivery.
Legora’s latest funding gives the company considerably greater resources to pursue that market. For law firm leaders and in-house counsel, its rapid expansion also points to a legal AI sector entering a new phase in which purchasing decisions are increasingly likely to concern long-term technology infrastructure rather than isolated productivity tools.
