Who owns Harvey? Ownership structure explained (2026)

Harvey has become the most closely watched company in legal AI. In under four years, it went from a seed-stage startup to an $11 billion business serving a significant share of the global legal profession. More than 142,000 lawyers across 1,500 organizations now run their most demanding work on Harvey's platform.

That trajectory raises a natural question: who actually owns Harvey? The answer matters because the company's ownership structure is genuinely unusual. The OpenAI Startup Fund backed Harvey at the seed stage. OpenAI became both an investor and, for years, the main model provider whose infrastructure Harvey's product ran on. That dual role creates a web of incentives that shapes major decisions the company makes.

This article breaks down Harvey's ownership structure, traces its funding history, identifies the key people in control, and explains what the ownership picture means for users and the legal industry.

Harvey was founded in 2022 by Winston Weinberg and Gabriel Pereyra. Weinberg was previously a securities and antitrust litigator at O'Melveny & Myers. Pereyra was a research scientist at Google DeepMind and Meta AI before co-founding the company.

The company is headquartered in San Francisco. Harvey builds AI tools specifically for legal and professional services work: contract analysis, due diligence, regulatory compliance, litigation research, and document drafting. The product is designed to handle complex legal tasks that require subject matter expertise, not just general-purpose text generation.

Harvey's user base spans elite law firms, corporate legal departments, and professional services organizations. The company has publicly referenced clients including Allen and Overy (one of the largest global law firms), PricewaterhouseCoopers, and others. Harvey positions its platform as a system for professional judgment, not just document automation.

The company's most recent confirmed valuation is $11 billion, set in March 2026 following a $200 million round co-led by GIC and Sequoia Capital. Total disclosed funding exceeds $1.2 billion. Harvey crossed $100 million in annual recurring revenue in August 2025 and reached roughly $190 million by the end of 2025; Sacra estimates ARR approached $300 million by mid-2026.

Harvey has no public stock. Its shares do not trade on any exchange. Ownership is distributed among founders, employees, and a concentrated group of venture capital and institutional investors. No IPO plans have been publicly announced.

Winston Weinberg holds a founder equity stake of undisclosed size. As CEO and co-founder of a company that has not disclosed specific ownership percentages, his precise economic stake is not publicly known. At a typical startup dilution trajectory, co-founder stakes at growth-stage valuations often range from mid-single digits to low double digits in percentage terms, depending on the size and number of funding rounds.

Gabriel Pereyra holds a co-founder stake, also undisclosed. His technical background from Google DeepMind and Meta is the foundation of Harvey's model development and AI architecture.

No specific voting structure or dual-class share arrangement has been publicly reported for Harvey.

Harvey has raised capital across multiple rounds in rapid succession:

Harvey's valuation has grown more than 100x since its first priced round, compressing what might take a decade of typical startup growth into under four years.

Sequoia Capital is Harvey's most consistent financial backer, having joined at the seed stage, led the Series A and Series D, and co-led the March 2026 growth round. That continuity across the company's history signals that Sequoia views Harvey as one of its highest-conviction bets in the legal AI category.

GIC, Singapore's sovereign wealth fund, co-led the March 2026 growth round at an $11 billion valuation. GIC has become an increasingly active late-stage technology investor across AI and enterprise software.

Kleiner Perkins co-led the $80 million Series B and the $300 million Series E, giving it a stake built across multiple rounds.

Andreessen Horowitz (a16z) led Harvey's $160 million round in December 2025 at an $8 billion valuation. Coatue Management co-led the Series E, and EQT Growth made a roughly $59 million strategic investment in October 2025 to support international expansion.

Conviction Partners and Elad Gil represent early-stage backers who have continued to participate through later rounds.

The OpenAI Startup Fund invested in Harvey's seed round in late 2022. This was one of the fund's earliest investments, and it created a relationship that now has several layers.

OpenAI is simultaneously:

This role is structurally unusual, though Harvey has reduced its exposure to any single supplier. After frontier reasoning models began outperforming its in-house legal model, Harvey scrapped that model and now routes tasks across multiple providers, sending work to Anthropic's Claude and Google's Gemini alongside OpenAI's systems through a model selector. OpenAI's commercial decisions still affect Harvey's costs and competitiveness, and OpenAI continues to benefit when Harvey's usage drives API revenue.

As Harvey grows, managing this relationship will be one of its more complex strategic challenges.

Harvey has not announced any plans for a public offering. The pace of its private fundraising, including a jump from $8 billion to $11 billion valuation in a matter of months, suggests the company has access to capital without needing public markets in the near term. No timeline for an IPO has been publicly discussed.

Weinberg co-founded Harvey in 2022 after leaving O'Melveny & Myers, where he worked as a securities and antitrust litigator. His background gives him direct insight into the workflows, pain points, and professional standards of the legal industry Harvey serves. This domain expertise is cited by investors as a core reason for the company's early success: the product was built by someone who understood legal work from the inside.

As CEO and co-founder, Weinberg controls day-to-day operations and company strategy. His combined role as founder, operator, and domain expert gives him significant influence over product direction.

Pereyra co-founded Harvey after research roles at Google DeepMind and Meta AI. His technical background shapes the company's approach to model development, safety, and evaluation. In a legal AI context, accuracy and reliability matter more than in consumer applications: a hallucinated legal citation has professional consequences. Pereyra's research pedigree is central to Harvey's claim that its platform is built for high-stakes professional use.

The composition of Harvey's full board has not been publicly disclosed. Given that Sequoia Capital has backed most of Harvey's rounds and led or co-led several of them, a Sequoia representative almost certainly holds a board seat. Kleiner Perkins, which co-led two rounds, likely also has board representation. No board chair has been publicly identified.

Legal AI tools operate in a regulated profession. Lawyers in the United States are governed by bar associations and professional conduct rules. Using AI to draft legal documents, advise clients, or conduct research raises questions about unauthorized practice of law, professional responsibility, and competence standards.

Several bar associations have issued guidance on AI use in legal practice. Harvey's platform is designed to be used by lawyers, not to replace them, which positions it on the safer side of these regulatory lines. But as Harvey's capabilities expand, the boundaries between AI assistance and AI-driven legal judgment will be tested.

Legal work demands high accuracy. An AI system that cites a nonexistent case, misquotes a statute, or mischaracterizes a contract clause can expose clients to liability and lawyers to disciplinary action. Harvey has emphasized its commitment to accuracy and citation verification, but the risk of AI hallucination in high-stakes professional work remains a live concern for regulators, bar associations, and potential enterprise customers.

Law firms handle among the most sensitive information in existence: client communications, unreleased deal details, litigation strategy, regulatory investigations. Any AI platform processing this information must meet stringent data isolation, confidentiality, and security requirements. Harvey has emphasized enterprise-grade data handling, but each new enterprise client requires independent assurance that their confidential matters are not used to train shared models.

Harvey's ownership structure has direct implications for the millions of lawyers and legal professionals who may eventually use its platform.

The OpenAI relationship is the most consequential ownership detail. If OpenAI decides to compete more directly in the enterprise legal market, Harvey's position as a preferred application layer becomes more complicated. For now the incentives are aligned: Harvey's usage drives API revenue for OpenAI, and OpenAI remains one of several frontier providers whose models power Harvey's product. If that alignment breaks, ownership will matter a great deal.

Sequoia's multi-round backing gives it significant economic stake and likely board influence. Sequoia has a track record of pushing portfolio companies toward IPOs or acquisitions at scale. As Harvey's valuation approaches levels where public market comparisons become relevant, that influence could shape the company's trajectory.

For users, the ownership picture signals durability. Harvey is not thinly funded: with more than $1.2 billion raised and backing from some of the most credible investors in enterprise software, the company is positioned to sustain long-term product investment.

Winston Weinberg is the CEO and co-founder of Harvey. He co-founded the company in 2022 after working as a litigator at O'Melveny & Myers. His legal background is central to how the company has built and positioned its product.

No. Harvey is a privately held company with no public stock listing. No IPO has been announced.

Harvey was co-founded in 2022 by Winston Weinberg (CEO, former lawyer) and Gabriel Pereyra (CTO, former research scientist at Google DeepMind and Meta).

Exact ownership percentages are not publicly disclosed. The most consistent institutional backer is Sequoia Capital, which has participated in every known round. Other major investors include GIC, Kleiner Perkins, Andreessen Horowitz, Coatue, Google Ventures (GV), and the OpenAI Startup Fund.

Harvey has raised more than $1.2 billion in total funding across nine known rounds, most recently a $200 million growth round in March 2026 at an $11 billion valuation.

The OpenAI Startup Fund was Harvey's seed investor. OpenAI's models originally underpinned Harvey's platform, though Harvey now routes work across OpenAI, Anthropic, and Google models. This makes OpenAI simultaneously an investor, a key supplier, and a potential competitor: a structurally unusual arrangement that analysts and investors have flagged as worth monitoring.
