Harvey, the legal artificial-intelligence startup, has raised $550 million in a new funding round that values the company at $15.5 billion, according to the company's own announcement, which said the financing was co-led by new investors Diffusion and Lightspeed Venture Partners. Bloomberg reported the resulting valuation as $15.6 billion; the discrepancy appears to reflect rounding, and this article uses the figure published in Harvey's announcement.
Sapphire Ventures and Whale Rock also joined as new backers, alongside a roster of returning investors that includes Sequoia, Kleiner Perkins, Andreessen Horowitz, Coatue, GIC and Goldman Sachs Alternatives. The round brings Harvey's total funding to more than $1.5 billion, making it the most heavily capitalized legal AI company to date, and follows a rapid string of re-valuations: the startup was valued at $8 billion late last year and $11 billion as recently as March, when it raised $200 million in a round led by GIC and Sequoia.
From Law Firms to Legal Departments
Founded in 2022 by Winston Weinberg, a former litigator at O'Melveny & Myers, and Gabriel Pereyra, a former DeepMind and Meta AI researcher, Harvey builds AI tools for contract analysis, due diligence, compliance and litigation work. The company says its software is now used by more than 200,000 lawyers across more than 2,400 customer organizations in over 70 countries, including roughly half of the Am Law 100, the ranking of the largest U.S. law firms by revenue, with clients such as O'Melveny, A&O Shearman and Latham & Watkins. It has also been expanding beyond law firms into corporate legal departments at companies including Comcast and Verizon.
Harvey said annual recurring revenue has now topped $400 million, and that proceeds from the new round will go toward product development and hiring as the company builds out what it calls infrastructure for legal teams to own and manage their own AI capabilities rather than relying solely on outside vendors. Alongside the funding announcement, Harvey disclosed it had acquired Guardrails AI, a startup focused on validating and controlling AI model outputs — its fourth acquisition of 2026.
The round is the latest sign of investor appetite for AI companies built around specific, high-value professional workflows rather than general-purpose foundation models, a shift that has drawn some of venture capital's largest checks this year into sectors like legal, sales and compliance software. For Harvey, the bigger test will be whether its revenue and customer growth can keep pace with a valuation that has nearly doubled twice within a year.
