Company profile
researched Aug 2026Harvey is a generative AI product for the legal industry developed by Counsel AI Corporation, providing customized large language model capabilities for law firms and in-house legal departments. Its products streamline workflows in areas including contract analysis, due diligence, compliance, and litigation. The platform is organized around several components: Agents (purpose-built agents that plan and execute legal tasks end to end and return cited, review-ready output), Vault (secure storage, organization, and bulk analysis of large document collections), Knowledge (research across legal, regulatory, and tax questions), Shared Spaces (cross-organization collaboration between firms, clients, and co-counsel with governance and ethical walls), Contract Intelligence, Command Center (usage analytics and benchmarking), Workflows (pre-built or firm-specific), Harvey Mobile, and an Ecosystem layer for integrations. The company also markets solution sets for innovation, litigation, transactional, in-house, law firm, and mid-sized firm use cases, and released a version called Harvey II.
The product name references Harvey Specter, the lead character of the legal drama Suits. Harvey publishes research on models, benchmarks, and methods, and states it builds alongside the open-source community. The platform supports enterprise controls such as SAML SSO, audit logs, IP allow-listing, and data lifecycle management, and lists SOC 2 Type II, ISO 27001, ISO 27701, ISO 42001, GDPR, and CCPA compliance. Harvey offers US, EU, and AU regional deployments.
Founding story
Harvey was founded in the summer of 2022 by Winston Weinberg, a securities and antitrust litigator at O'Melveny & Myers, and Gabriel Pereyra, a research scientist at Google DeepMind and Meta. The two were roommates in Los Angeles; Pereyra showed Weinberg OpenAI's GPT-3, and Weinberg concluded it could improve legal workflows. They built an early chain-of-thought prompt on GPT-3 focused on California tenant law and tested it on 100 legal questions from a public forum, hiring three attorneys to judge whether the answers could be sent to clients unchanged; 86 of the 100 were approved. They then contacted Sam Altman and OpenAI General Counsel Jason Kwon about the results, met OpenAI's C-suite on July 4, 2022, and OpenAI became their seed investor, also granting early access to GPT-4.
Business model
Harvey sells software to legal organizations β law firms, corporate in-house legal departments, and professional services networks β deployed firmwide or enterprise-wide in many cases. Alongside the software, Harvey embeds legal engineering teams that work with customers to build and continuously improve custom agents. The company also offers regional deployments (US, EU, AU), integrations with existing tools, and Harvey Academy training resources.
Harvey reported revenue of $190 million for 2025. Public sources describe commercial access to product bundles combining its AI assistant, specialized models such as case law models, and Vault, but do not detail pricing terms.

βΈFull profile β market position, technology, go-to-market, geography, history, risks & controversies
Market position
Harvey is a widely adopted legal AI vendor, reporting use by the majority of the AmLaw 100, more than 100,000 lawyers, and organizations in 60-70+ countries, with valuations rising from $715 million in 2023 to $11 billion in 2026. Allen & Overy's 2022-2023 trial was reported as the first known use of a generative AI product within the UK magic circle firms. The company has been named to the Time100 Most Influential Companies, a LinkedIn Top 50 Startup of 2025, and a Disruptor 50 list of innovative AI companies.
Harvey positions itself as domain-specific rather than general-purpose AI, combining legal-specific models and benchmarks with embedded legal engineering teams, customer-built custom agents (more than 25,000 in operation), cross-organization Shared Spaces with ethical walls, deep integration into existing legal tooling, and enterprise security certifications. Its heavy hiring of former large-firm attorneys into product and sales roles has been cited as a major factor in adoption.
Technology
Harvey provides customized large language models and agentic systems for legal work, originating from chain-of-thought prompting on GPT-3 and early access to GPT-4 through OpenAI. The platform routes tasks to purpose-built agents, supports long-horizon agents handling multi-step workflows over extended periods (for example fund formation), and returns cited outputs. It runs on Microsoft Azure and connects to more than 500 regional knowledge sources plus systems such as Ask LexisNexis, Rettsdata, iManage, NetDocuments, SharePoint, Google Drive, Aderant, Ironclad, and APIs, with surfaces in Word, Outlook, browsers, email, and mobile. Harvey publishes models, benchmarks, and research, and achieved AIUC-1 certification for AI agents in July 2026.
Go-to-market
Harvey sells directly to firms and legal departments, using a sales team staffed substantially by former large-firm ('Big Law') attorneys, a factor reported as central to convincing lawyers to trial the software. Adoption often begins with pilots or practice-group trials before firmwide rollouts. The company supports go-to-market with published customer stories, ROI calculators for law firms and in-house teams, a demo-request funnel, Harvey Academy training, a Customer Advisory Board launched in March 2026, and partnerships including Microsoft, Lumio, and sports sponsorships.
Global law firms (including AmLaw 100 and international firms), mid-sized firms, corporate in-house legal teams at Fortune 500 enterprises, asset management firms, and professional services networks such as PwC.
Geography
Headquartered in San Francisco, California, with a Chicago office opened per company blog listings and US, EU, and AU platform regions. Customers span 60-70+ countries, including the UK, Ireland, Germany, Spain, Poland, South Korea, Canada, and Australia.
History
After its 2022 founding, Harvey raised a $5 million round led by the OpenAI Startup Fund in November 2022, followed by $23 million led by Sequoia Capital in April 2023, an $80 million Series B in December 2023, a $100 million Series C in July 2024, a $300 million Series D in February 2025, a $300 million Series E in June 2025, a $160 million Series G-stage round led by Andreessen Horowitz in December 2025, and $200 million at an $11 billion valuation in March 2026, bringing total funding above $1 billion. Gordon Moodie, a corporate partner at Wachtell, Lipton, Rosen & Katz, joined as chief product officer in July 2023. Harvey had 82 employees in March 2024 and said it planned to double headcount by year-end, recruiting many lawyers from large US firms including White & Case, Latham & Watkins, Skadden, Gunderson Dettmer, Katten Muchin Rosenman, and Paul Weiss. In May 2024 Harvey launched its products on Microsoft Azure and began offering broader commercial access to products such as its case law models and bundles including its AI assistant, specialized models, and Vault. In 2026 the company announced a strategic investment from Goldman Sachs and J.P. Morgan, expanded collaboration with Microsoft, acquired or absorbed Y Combinator-backed Benchmark, appointed Steve Zad as Chief Revenue Officer, opened a Chicago office, and undertook brand and sports sponsorship activity.
Risks & controversies
Customers and observers have flagged the need for human verification of outputs: Allen & Overy's David Wakeling stated that everything coming out of the system must be validated and checked, and the firm noted output requires careful review by a lawyer. Paul Weiss reported it was not using hard metrics such as time saved to assess productivity gains because the review effort required made efficiency gains difficult to measure. Reported usage statistics also vary between Harvey's website and its funding announcements.
