Legal AI startups raised $9.9B across 352 equity rounds worldwide between January 2023 and September 2026. Annual legal AI funding grew from $608M in 2023 to $4.3B in 2025, and the first nine months of 2026 brought in $2.9B, about level with the same months of 2025 on 11% fewer rounds.
The money sits at the top. Six rounds of $300M or more raised $3.2B, close to a third of everything since 2023, and Harvey raised three of them. In 2026 alone, four rounds took 52% of the year’s $2.9B. Harvey was valued at $715M in December 2023 and at $15.5B in September 2026, about 22 times as much.

Legal AI Funding by Year, 2023 to 2026
AI startups in legal tech raised $608M in 2023. They raised $2.2B in 2024 and $4.3B in 2025. Round counts climbed from 56 in 2023 to 81 in 2024 and 130 in 2025.
January to September 2026 brought in $2.9B, about level with January to September 2025, on 85 rounds against 95 a year earlier.
| January to September | Rounds | Money raised |
|---|---|---|
| 2023 | 38 | $399M |
| 2024 | 62 | $1.8B |
| 2025 | 95 | $2.9B |
| 2026 | 85 | $2.9B |
Legal Tech Rank Among AI Verticals
For all that growth, legal technology is still a small corner of AI. A company can belong to more than one industry in this comparison, and the ranking uses US and European rounds only.
In January to September 2026, legal tech holds 2.1% of US and European AI rounds and ranks 16th of 17 verticals. It was 15th in 2025 with 2.5%, and 17th in both 2023 and 2024.
Largest Legal AI Funding Rounds
Where legal tech stands out is the size of its biggest rounds. Of 326 rounds with a public size, six reached $300M or more, and Harvey raised three of them.
| Company | Round | Date |
|---|---|---|
| Clio | $900M | July 2024 |
| Harvey | $300M | February 2025 |
| Harvey | $300M | June 2025 |
| Clio | $500M | November 2025 |
| Legora | $600M | March 2026 |
| Harvey | $550M | September 2026 |
The largest, Clio’s $900M in 2024, mixed new shares with shares sold by existing holders. Filevine‘s $400M from September 2025 is not on the list because it was two smaller rounds announced together. Harvey’s latest, the $550M it announced in September 2026 at a $15.5B valuation, was co-led by Lightspeed and Diffusion.
Legal AI Funding Concentration in 2026
Max Junestrand, CEO of Legora, Harvey’s closest rival, told 20VC that legal AI is a winner-takes-all market, where number one takes 90% and numbers two to ten share the other 10%. The 2026 funding numbers put two companies at the top.
Four rounds took $1.5B of the $2.9B raised in January to September 2026, or 52%. The largest, at 21%, was Legora’s $600M Series D, counting the extension it added in April. Harvey’s two rounds, $200M in March and $550M in September, took 26%. Between them, the two companies took almost half of the year’s money. Norm Ai‘s $120M in July was the fourth largest. The other 81 rounds shared $1.4B.
The Six Largest Rounds Since 2023
Over the whole window the top is a little wider. Six rounds contributed $3.2B of the $9.9B raised since January 2023.
The first 18 months, January 2023 to June 2024, added only $1.1B across 101 rounds.
Harvey has three of the six rounds, Clio two and Legora one. Clio sells practice software to law firms, a different product from the two AI assistants.
Legal AI Funding in Europe vs the US
Europe gained ground fast in 2026. Between the first nine months of 2025 and the first nine months of 2026, Europe’s legal tech money more than doubled, from $425M to $1.1B. US money fell from $2.1B to $1.5B.
| Jan to Sep | Europe rounds | Europe money | US rounds | US money |
|---|---|---|---|---|
| 2023 | 14 | $90M | 22 | $294M |
| 2024 | 20 | $230M | 32 | $597M |
| 2025 | 22 | $425M | 57 | $2.1B |
| 2026 | 26 | $1.1B | 41 | $1.5B |
Legora explains much of that rise. Take it out and Europe’s money still rose 37%.
Legal Tech Funding by European Country
Sweden’s $630M in 2026 is almost all Legora. The United Kingdom closed more rounds, 9 against Sweden’s 6, and raised $343M, up from $189M.
Legora’s rounds are counted in Stockholm here, though the company is now headquartered in New York. In March, Junestrand joked that legal spending runs nine to one, the US over Europe: “It’s nine to one in terms of legal spending; it turns out the Americans love to sue each other much more than we like to do in Europe.”
Legal AI Series A Funding Gap in Europe
Europe holds its own at the start and in the middle. In January to September 2026, Europe closed 16 pre-seed and seed rounds against 17 in the US, and 6 Series B rounds, the same as the US. Series A is where it falls behind, with 2 European rounds against 11 American ones.
| Stage, Jan to Sep 2026 | Europe | United States |
|---|---|---|
| Pre-seed and seed | 16 | 17 |
| Series A | 2 | 11 |
| Series B | 6 | 6 |
| Series C or later | 2 | 5 |
Across the full window from January 2023 to September 2026, seed rounds make up 54% of European legal tech rounds and 47% of US rounds. Series C or later is 7% in Europe and 14% in the US. For a European founder in legal tech, Series A is the thin spot.
US Investors in European Legal AI Rounds
Most of Europe’s bigger legal tech funding rounds bring in American money. US-based investors joined 8 of the 11 European legal tech rounds of $50M or more between January 2023 and September 2026.
| Company | Round | Date | US investor joined | Lead as announced |
|---|---|---|---|---|
| Luminance | $75M | Feb 2025 | Yes | Point72 Private Investments |
| Noxtua | $92M | Apr 2025 | No | C.H.Beck |
| Legora | $80M | May 2025 | Yes | ICONIQ and General Catalyst |
| Legora | $150M | Oct 2025 | Yes | Bessemer Venture Partners |
| Orbital | $60M | Jan 2026 | Yes | Brighton Park Capital |
| Summize | $50M | Jan 2026 | No | None named |
| Lawhive | $60M | Feb 2026 | Yes | Mitch Rales |
| Legora | $600M | Mar 2026 | Yes | Accel |
| Lexroom | $50M | May 2026 | Yes | Left Lane Capital |
| Wordsmith | $84M | Jun 2026 | No | None named |
| Xapien | $56M | Sep 2026 | Yes | Spectrum Equity |
In the other three, Noxtua, Summize and Wordsmith, no investor with a known home base is American. Wordsmith’s was the latest, an $84M round in June 2026 that counts the extension it added in August.
Legal AI Funding by Segment
Legal AI assistants and research, the AI tools that law firms and in-house legal teams use for drafting and legal research, took 30% of the money from January 2023 to September 2026, about $3B, with 13% of the rounds, or about one in eight. Harvey and Legora both sit in this segment.
| Segment | Rounds | Money | Share of rounds | Share of money | Companies that raised $50M+ |
|---|---|---|---|---|---|
| Legal AI assistants and research | 44 | $3B | 13% | 30% | 5 |
| Law-firm practice management and billing | 32 | $2.2B | 9% | 22% | 4 |
| Compliance, tax and privacy | 56 | $1B | 16% | 10% | 6 |
| Contracts and CLM | 52 | $873M | 15% | 9% | 7 |
| Plaintiff and personal injury | 19 | $664M | 5% | 7% | 3 |
| AI-native law firms and consumer legal | 36 | $588M | 10% | 6% | 5 |
| Litigation, disputes and courts | 43 | $528M | 12% | 5% | 2 |
| In-house legal and legal ops | 22 | $456M | 6% | 5% | 3 |
| IP and patents | 31 | $343M | 9% | 3% | 3 |
| Transactions, due diligence and real estate | 17 | $264M | 5% | 3% | 2 |
Compliance, tax and privacy runs the other way, with the most rounds of any segment (56) and about a tenth of the money. AI-native law firms, which sell legal work itself rather than software, hold 10% of the rounds and 6% of the money. The newest of them is Arceus, which announced $17M in October 2026, after this report’s window.
Plaintiff and Personal Injury Law Rounds Decline
Plaintiff law looked like the next corner to grow. When EvenUp raised in October 2025, its co-founder Rami Karabibar told Fortune he expected a winner-take-most market, and called it EvenUp’s game to lose.
In the first nine months of 2026, US and European plaintiff and injury rounds fell from nine to one. EvenUp, Eve and Supio, the three biggest raisers in plaintiff law, all closed their latest rounds in 2025.
No segment doubled its round count. Compliance, tax and privacy grew most, from 8 rounds to 13.
Legal AI Round Sizes by Stage
Legal tech rounds start small. At seed and Series A, the typical legal tech round in the US and Europe is a little smaller than the typical AI round. From Series B on, it is bigger.
| Stage | Legal tech median | All AI median |
|---|---|---|
| Seed | $4M | $5M |
| Series A | $15M | $16M |
| Series B | $44M | $37M |
| Series C | $88M | $70M |
| Series D | $143M | $105M |
The median legal tech Series B is $44M, against $37M across all AI. Late rounds are a smaller share of legal tech deals: Series C or later was 10% of legal tech rounds in January to September 2026, against 15% for all AI. Yet those late rounds take most of the money. Series C or later took 59% of 2026’s US and European legal tech money.
Legal AI Unicorn Valuations
Seven legal tech companies have a latest confirmed valuation of $1B or more as of September 2026.
| Company | Earliest checked | Latest |
|---|---|---|
| Harvey | $715M (Dec 2023) | $15.5B (Sep 2026) |
| Legora | $675M (May 2025) | $5.6B (Mar 2026) |
| Clio | $3B (Jul 2024) | $5B (Nov 2025) |
| EvenUp | $325M (Jun 2023, press-reported) | $2B+ (Oct 2025) |
| Enter | $350M (Sep 2025) | $1.2B (May 2026) |
| Norm Ai | One value only | $1.2B (Jul 2026) |
| Eve | One value only | $1B+ (Sep 2025) |
Harvey is worth almost three times Legora. It was valued at $715M in December 2023, and by September 2026 it was worth about 22 times that. Ryan McClead, a principal at Sente Advisors, said in a Bloomberg Law piece in 2025 that legal AI was in the phase where market share matters more than revenue.
Legal AI Funding by City
New York City closed the most legal tech rounds between January 2023 and September 2026, 49 against San Francisco’s 48. San Francisco raised the most money, $2.5B, and Harvey alone accounts for $1.7B of it.
| City | Money | Rounds | Largest single company |
|---|---|---|---|
| San Francisco | $2.5B | 48 | Harvey, $1.7B |
| Vancouver | $1.4B | 2 | Clio, $1.4B |
| New York City | $1.2B | 49 | No company holds half |
| Stockholm | $886M | 9 | Legora, $866M |
| London | $594M | 40 | No company holds half |
| Salt Lake City | $400M | Two rounds announced together | Filevine, $400M |
| Toronto | $253M | 11 | Not shown |
| Los Angeles | $228M | 13 | Not shown |
| San Mateo | $168M | 4 | Eve, $164M |
| Sao Paulo | $150M | 5 | Enter, $135M |
| Seattle | $129M | 7 | Supio, $85M |
| Cambridge, UK | $115M | 2 | Luminance, $115M |
In eight of the twelve cities, one company raised half the money or more. Clio in Vancouver, Legora in Stockholm and Filevine in Salt Lake City are the clearest cases. New York City and London are the biggest exceptions. London closed 40 rounds, and in neither city does one company hold half the money.
Legal AI Startups to Watch
The ten largest raisers get most of the coverage. Bot Memo scored the 45 legal tech companies outside that group that raised at least twice since January 2023, and ranked them on how soon they raised again and how much bigger the new round was, plus valuation growth, round count, a named lead and recency.
| Rank | Company | City | Why it ranks | Score |
|---|---|---|---|---|
| 1 | Crosby | New York City | $60M round, 10 times its Jun 2025 seed | 7.9 |
| 2 | Wordsmith | Edinburgh | $84M round, 17 times its Jun 2024 seed | 6.8 |
| 3 | Lexroom | Milan | $50M round, 22 times its Mar 2025 seed | 6.4 |
| 4 | Sandstone | New York City | Seed to Series A in 5 months | 6.0 |
| 5 | Jupus | Cologne | $15M round, 10 times its May 2024 seed | 3.9 |
| 6 | Ivo | San Francisco | $55M round, 11 times its Apr 2024 seed | 3.8 |
| 7 | Solve Intelligence | London | $40M round, 13 times its Nov 2023 seed | 3.7 |
| 8 | Patlytics | New York City | $40M round, 8.9 times its Apr 2024 seed | 3.7 |
| 9 | Ankar | London | Seed to Series A in 7 months | 3.6 |
| 10 | SimpleClosure | Los Angeles | $15M round, 10 times its Sep 2023 pre-seed | 3.5 |
| 11 | GC AI | San Francisco | Series A to Series B in 5 months | 3.4 |
| 12 | Xapien | London | $56M round, 9.4 times its Apr 2023 seed | 2.3 |
Crosby, which sells fixed-price contract review, tops the list with a $60M round, 10 times its June 2025 seed. Wordsmith, from Edinburgh, is second on an $84M round, 17 times its June 2024 seed. Lexroom, a legal research tool from Milan, is third on a $50M round, 22 times its March 2025 seed.
Largest Legal AI Companies by Segment
Each of the six largest legal tech segments has a few companies that raised most of its money.
Harvey raised eight rounds in the assistants segment, from $21M in 2023 to $550M in 2026. Clio leads practice management with $900M in 2024 and $500M in 2025. In compliance, Norm Ai’s $120M in 2026 and Blue J’s $122M in 2025 are the largest rounds. EvenUp raised $51M, $135M and $150M across 2023, 2024 and 2025 before plaintiff law went quiet.
Most Active Legal AI Investors
The two investors that joined the most legal tech rounds mostly back companies early. Y Combinator joined the most rounds, 26, and 19 of them were pre-seed to Series A. The LegalTech Fund is next with 21, 14 of them pre-seed to Series A.
Elad Gil, an angel investor, leans the other way. Six of the ten rounds he joined were Series C or later, all of them Harvey’s.
How Harvey Compares With the Rest of Legal AI
Back to the 90% claim. The other six legal tech companies valued at $1B or more are worth at least $16B together. Harvey alone is at $15.5B. To double its September 2026 valuation, it would have to reach $31B.
Key Takeaways
- Legal AI startups raised $9.9B in 352 equity rounds worldwide from January 2023 to September 2026, with annual funding rising from $608M in 2023 to $4.3B in 2025.

Methodology
This report is based on 352 legal tech equity rounds worldwide, announced between January 2023 and September 2026. All amounts are in USD. The data is verified AI venture rounds in legal tech from the Bot Memo repository.
- Money: equity rounds only; debt is left out. Round sizes are as announced. Clio’s $900M (July 2024) mixed new shares with secondary sales. Filevine’s $400M (September 2025) was two rounds announced together. An extension closed weeks after its round counts as part of that round.
- Comparisons: Europe against the US uses the same months of each year, January to September. Series C or later includes growth rounds.
- Attribution: every investor named on a round is credited with the full round, so figures read as rounds joined and are never added across firms.
- Valuations: announced by the company, or reported by the press where marked. They are company values, not returns.
- Segments: each company sits in one segment, set by what it sells, so the ten segments add up to the vertical.
- Cities: cities, not metro areas. Each company’s head office, or the city its round lists.
- Companies to watch: companies outside the ten largest raisers with two or more rounds in the window, ranked on time between rounds, round-size growth, valuation growth, round count, a lead named in the company’s own release, and recency. Weights are printed on the chart; no segment gets more than three rows.
