Overview

Harvey builds AI software for lawyers. Law firms and corporate legal departments use it to research case law, draft and review contracts, analyse large sets of documents in due diligence, prepare first drafts of memos, and run multi-step legal workflows with AI agents. It has become the best-known legal AI company in the world, used by most of the largest US law firms.

Winston Weinberg, a former litigation associate at the law firm O'Melveny & Myers, and Gabe Pereyra, a former research scientist at Google DeepMind and Meta, founded Harvey in 2022. Its first backer was the OpenAI Startup Fund, and it was among the first companies to get early access to GPT-4. The company is based in San Francisco and has been opening offices around the world, including London, New York, and plans for Tokyo and Boston.

What lawyers use it for

  • Assistant: asking legal questions, summarising documents and drafting in a firm's own style.
  • Vault: uploading thousands of documents, for example in a merger data room, and asking questions across all of them.
  • Knowledge: research grounded in legal, regulatory and tax sources.
  • Agents and workflows: multi-step tasks such as reviewing contracts against a playbook, preparing a due diligence report or tracking regulatory changes.
  • Contract intelligence and intake: tools for in-house teams to manage contracts and incoming legal requests.

Business model

Harvey sells annual enterprise subscriptions, usually priced per seat, to law firms and corporate legal departments. Large firms often license it for thousands of lawyers. Pricing is high compared with general AI tools, justified by legal-specific accuracy, security and integration with legal workflows. Harvey doesn't publish revenue; press reports in 2026 cited figures in the hundreds of millions of dollars in annual recurring revenue, but the company hasn't confirmed them in its announcements, so we show revenue as not disclosed.

Funding history

Harvey raised money unusually quickly. It went from a seed round in 2022 to several large rounds a year:

  • March 2026: US$200 million at an US$11 billion valuation, co-led by GIC and Sequoia Capital.
  • September 2026: US$550 million at a US$15.5 billion valuation, co-led by Diffusion and Lightspeed Venture Partners. New investors Sapphire Ventures and Whale Rock joined existing backers including Sequoia, Kleiner Perkins, Andreessen Horowitz, Coatue, Conviction, Elad Gil, GIC and Goldman Sachs Alternatives.

Its valuation rose about 40% in six months. Frequent rounds like this are typical of the current AI market, where investors compete to back category leaders.

Customers

Harvey says 80% of the Am Law 100, the largest US law firms by revenue, use its platform, along with in-house legal teams at five of the Fortune 10. International firms in the UK, Europe, the Middle East and Asia are customers too. For a professional services market that has historically been slow to adopt technology, that level of penetration within four years is remarkable.

Why law is a strong market for AI

Legal work is text-heavy, structured and expensive. Much of it involves reading, comparing and drafting documents, exactly what large language models do well. At the same time, mistakes are costly, confidentiality is critical, and lawyers need to cite authoritative sources. That combination favours specialised tools with strong security and accuracy over general chatbots. It also raises a long-term question about the billable hour: if AI makes a task ten times faster, firms will need to rethink how they price their work.

Competitors

Harvey competes with legal information giants Thomson Reuters (which bought Casetext and its CoCounsel product) and LexisNexis (Lexis+ AI), with other legal AI startups such as Legora, and with general AI assistants that lawyers use informally. Its advantages are its early lead with elite firms, the trust that comes from that customer list, and a broad product suite.

How to judge a legal AI vendor

  • Test it on your own matters and compare the output with what a senior associate would produce.
  • Check how it cites sources and how often citations are wrong.
  • Confirm where client data is processed and whether it is used for training.
  • Ask how it fits your document management system and existing workflows.

Comparing vendors on a valuation multiple is also useful context; our guide to SaaS valuation multiples explains how investors price fast-growing software companies like Harvey.

Firms that run structured pilots, with clear success measures agreed by partners and the IT team, usually reach a decision faster and get much better adoption among lawyers once the tool is rolled out across the whole firm.

What comes next

The things to watch are revenue disclosures, expansion in Asia and Europe, the growth of agentic workflows, competition with Thomson Reuters and LexisNexis, and whether law firms change pricing models as a result of AI.

Takeaways by reader

Law firm partners: AI tools are becoming standard among the largest firms, so clients will expect efficiency gains to show up in fees. Founders: Harvey shows how a vertical AI company can win a conservative industry by starting with its most demanding customers. Investors: watch whether revenue keeps pace with a valuation that has risen several times a year.
