Legal AI went from a niche experiment to one of the fastest growing verticals in enterprise software. Legal tech startups raised a record $2.4 billion in 2025, and 2026 is already outpacing that. The catalyst is simple: legal work is expensive, repetitive, and document-heavy, which makes it one of the best categories for AI to deliver measurable ROI quickly. Law firms and in-house legal teams are no longer running pilots. They are buying and deploying at scale. Below are the top legal AI startups that have raised the most significant funding in 2026, ranked by total funding raised.
Key Takeaways
- Harvey crossed $1 billion in total funding in March 2026 with a $200M round at an $11B valuation, more than 3.5x its valuation from a year prior
- Legora raised $600M in its Series D (including a $50M extension in April 2026), valuing the Stockholm-based company at $5.6B
- Legora surpassed $100M in ARR, placing it among the fastest-growing enterprise software companies in history
- Harvey is now used by more than 100,000 lawyers across 1,300 organisations globally, including the majority of the AmLaw 100
- Harvey reached $190M ARR by January 2026, up from $100M in August 2025, a 3.9x year-on-year increase
- Ironclad surpassed $200M in ARR in January 2026, growing nearly 40% year on year, despite not raising a new round since 2022
- Legal tech VC funding hit an all-time record in 2025 and is continuing to accelerate in 2026
- Sequoia Capital has led three of Harvey’s funding rounds, making it the most committed institutional backer in legal AI
- The category is splitting into two lanes: AI-native platforms for lawyers (Harvey, Legora) and AI-layered CLM for legal ops (Ironclad, Filevine)
1. Harvey
Total Funding: $1.2B+ | Latest Valuation: $11B | Latest Round: $200M Series G (March 25, 2026)
Harvey is the most funded pure-play legal AI company in the world. Founded in 2022 in San Francisco by Gabe Pereyra and Winston Weinberg, the company has raised over $1.2 billion across 10 rounds in less than four years, a pace that rivals the fastest-growing enterprise software companies on record.
The $200 million Series G closed on March 25, 2026, co-led by GIC and Sequoia Capital, with participation from existing investors Andreessen Horowitz, Coatue, Conviction Partners, Elad Gil, Evantic, and Kleiner Perkins. Sequoia has now led three of Harvey’s funding rounds. The round values Harvey at $11 billion, more than 3.5x its valuation from twelve months prior. Harvey’s valuation trajectory through 2025 and into 2026 reads: $3B (February 2025 Series D), $5B (June 2025 Series E), $8B (December 2025 Series F led by Andreessen Horowitz), $11B (March 2026 Series G).
Harvey is now used by more than 100,000 lawyers across 1,300 organisations in 60 countries. Its customer base includes the majority of the AmLaw 100, over 500 in-house legal teams, and 50 asset management firms. Recent enterprise wins include NBCUniversal, HSBC, DLA Piper International, McCann Fitzgerald, and Paris Saint-Germain. The platform runs more than 25,000 custom AI agents for customers, with embedded legal engineering teams deployed inside major law firms to build and optimise those agents. Harvey announced a strategic partnership with contract management platform Ironclad in August 2025. In April 2026, Slaughter and May, one of the UK’s most prestigious law firms, adopted Harvey firmwide.
Harvey crossed $100 million in ARR in August 2025, roughly three years after founding. By January 2026, that figure had reached $190 million, a 3.9x increase year on year and one of the fastest ARR growth rates ever recorded in enterprise software. The company plans to use the Series G capital to expand AI agent capabilities and grow its embedded legal engineering teams globally.

2. Legora
Total Funding: $866M | Latest Valuation: $5.6B | Latest Round: $600M Series D total ($550M March 10 + $50M extension April 30, 2026)
Legora is the fastest-growing legal AI company outside the US and the second most valuable legal AI startup in the world. Founded in 2023 in Stockholm by Max Junestrand and Sigge Labor, the company has raised $866 million in total across eight rounds, with the bulk of that coming in a single Series D that has now totalled $600 million.
The initial $550 million Series D closed on March 10, 2026, led by Accel, at a $5.55 billion valuation. That tripled the company’s valuation from the $1.8 billion it achieved just five months earlier in October 2025. Participating investors included Benchmark, Bessemer Venture Partners, General Catalyst, ICONIQ Capital, Redpoint Ventures, and Y Combinator, as well as new investors Alkeon Capital, Bain Capital, Firstmark Capital, Menlo Ventures, Sands Capital, Starwood Capital, and Salesforce Ventures.
On April 30, 2026, Legora closed a $50 million extension to the Series D, led by NVentures (Nvidia’s VC arm) and Atlassian, alongside Adams Street Partners, AirTree, Barclays, Geodesic Capital, Insight Partners, Liberty Global, and Nikesh Arora. The extension pushed the total Series D to $600 million and the valuation to $5.6 billion post-money.
Legora recently crossed $100 million in ARR, which puts it among the fastest-growing enterprise software companies in history given it was founded just three years ago. Customers save an average of 4.3 non-billable hours per lawyer per week. The platform now serves tens of thousands of legal professionals at major firms including White & Case, Linklaters, Cleary Gottlieb, and Goodwin, as well as corporate legal departments at Barclays and others. Legora acquired Qura to build what it describes as the world’s leading AI-native legal research platform.
The company opened its first US office in New York in March 2025, and has since expanded to Houston and Chicago, with plans to grow to more than 300 US employees by end of 2026.

3. Ironclad
Total Funding: $333M | Latest Valuation: $3.2B | Last Round: $150M Series E (January 2022)
Ironclad has not raised a new funding round in 2026. Its last disclosed round was a $150 million Series E in January 2022, led by Franklin Templeton, at a $3.2 billion valuation. Total funding stands at $333 million across seven rounds. It belongs on this list for a different reason: it is executing.
Founded in 2014 by Jason Boehmig and Cai GoGwilt, and now led by CEO Dan Springer (who joined from DocuSign in April 2025), Ironclad builds AI-powered contract lifecycle management (CLM) software for enterprise legal teams. In January 2026, Ironclad surpassed $200 million in ARR, up from $196 million at end of 2025, growing nearly 40% year on year. It is one of a small number of legal tech companies to cross that threshold.
In March 2026, Ironclad launched Ironclad Assistant, a suite of agentic AI tools that can autonomously handle contract-related tasks across the full contract lifecycle, including an archive agent, intake agent, redlining agent, and conversational search. The platform leverages LLMs from OpenAI, Anthropic, and Google. Ironclad has over 1,000 enterprise customers and approximately 796 employees as of early 2026.
Ironclad also announced a strategic partnership with Harvey in August 2025, integrating Harvey’s AI capabilities into Ironclad’s contract workflows, which positions both companies as complementary rather than competing.

4. Filevine
Total Funding: $400M+ | Stage: Growth | Last Known Round: $400M across two rounds (disclosed September 2025)
Filevine is a Salt Lake City-based legal practice management platform founded in 2014. It disclosed two previously undisclosed funding rounds totalling $400 million in September 2025, led by Insight Partners and co-led by Accel and Halo Experience Co. for the second round. It is now one of only four legal tech companies to appear in the Forbes Cloud 100 for 2025.
The platform serves nearly 6,000 customers and 100,000 users across law firms of all sizes. Filevine covers case management, timekeeping, billing, document management, and legal drafting in one integrated system. The company has been expanding its AI layer aggressively, with custom LLMs trained specifically on legal data rather than generic models. That product differentiation has driven strong growth and is the core of its investor narrative.
Key Investors: Insight Partners, Accel, Halo Experience Co.
5. Eudia
Total Funding: $105M | Stage: Series A | Latest Round: $105M Series A (February 2025)
Eudia is a Palo Alto-based legal AI startup founded in 2023 by Omar Haroun, David Van Reyk, and Ashish Agrawal. The company focuses exclusively on in-house legal teams at Fortune 500 companies, unlike Harvey and Legora which serve both law firms and enterprise clients.
It raised $105 million in a Series A led by General Catalyst, with a unique funding structure: $75 million of that was earmarked specifically for acquisitions, enabling the company to consolidate alternative legal service providers rather than just build software. CEO Omar Haroun previously sold Text IQ to Relativity in 2021, which gives the team a track record on exits. Eudia has around 209 employees as of early 2026 and has been signing enterprise legal departments at a fast clip.

The Bigger Picture
Legal AI is moving faster than most corporate buyers expected, and the funding numbers reflect that.
The law firm channel is now proven. Harvey’s 100,000 lawyers across 1,300 organisations is not a projection. It is a deployed user base inside the world’s most compliance-conscious institutions. Law firms do not move fast. The fact that Harvey has firmwide adoption at Slaughter and May, DLA Piper, and most of the AmLaw 100 is a signal that the technology has cleared the bar that matters most in legal: trust.
Europe is producing a serious challenger. Legora’s $5.6 billion valuation and $100M+ ARR makes it the most credible non-US legal AI company in the world. The April 2026 extension, backed by Nvidia and Atlassian, signals that strategic corporate investors now see legal AI infrastructure as worth owning a stake in, not just using.
The CLM category is not dead. Ironclad’s $200M ARR and nearly 40% growth in 2026 is the counter-argument to anyone who assumed AI-native startups would displace contract lifecycle management tools quickly. The reality is that CLM and AI-native legal tools are increasingly complementary, which the Harvey-Ironclad partnership formalised in 2025.
The category is splitting clearly. On one side: AI-native platforms built for lawyers doing research, drafting, and due diligence (Harvey, Legora). On the other: AI-layered workflow tools built for legal ops teams managing contracts at scale (Ironclad, Filevine). Both lanes are seeing significant adoption and investment. The companies that will dominate the next five years are likely those that can serve both sides of that divide.
Legal work is a $1 trillion global industry. Less than 5% of it is currently automated. The funding pace suggests investors believe that number is about to change fast.
