Harvey

Harvey is a privately held legal artificial intelligence company headquartered in San Francisco and founded in 2022 by former securities litigator Winston Weinberg and former Google DeepMind research scientist Gabriel Pereyra. It is venture-backed rather than owned by a strategic parent, and a funding round completed in September 2026 valued the business at $15.5 billion.

The company began with a seed investment from the OpenAI Startup Fund in 2022 and raised successive rounds led by Sequoia Capital, Kleiner Perkins, GIC and, most recently, Diffusion and Lightspeed Venture Partners, reaching $550 million at a $15.5 billion valuation in September 2026. Through 2026 it also acquired several smaller firms, among them Hexus, the investment analysis platform Benchmark and the AI reliability company Guardrails AI, adding engineering teams focused on in-house legal work.

Harvey at a glance:

• Founded: Founded in 2022 in San Francisco by Winston Weinberg, previously a litigator at O'Melveny & Myers, and Gabriel Pereyra, formerly of Google DeepMind and Meta.
• Headquarters: Headquartered in San Francisco, California, serving customers in more than 70 countries, with additional offices including New York and a planned engineering base in Bangalore.
• Ownership: Private and venture-backed, with investors including Sequoia Capital, Kleiner Perkins, Andreessen Horowitz, Coatue, GIC, Lightspeed Venture Partners and the OpenAI Startup Fund.
• Legal Technology Portfolio: Sells a single product, Harvey, an AI platform covering legal research, drafting, document review, contract intelligence and agentic workflows for legal and professional services.
• Market Focus: Sells to large law firms and to enterprise in-house legal and professional services teams, with heavy concentration in the Am Law 100 and the largest global accounting firms.

What legal teams should know: Harvey is priced and scoped for large organizations and its roots are in elite law firm work, so smaller departments should test whether the commercial model fits before engaging procurement. Capital is plentiful and the company is acquiring quickly, which brings rapid feature change. It partners with contract platforms such as Ironclad rather than replacing systems of record.
