Harvey, the legal AI platform founded by Winston Weinberg and Gabe Pereyra, has become one of the most remarkable success stories in Silicon Valley. The company counts the OpenAI Startup Fund, Sequoia Capital, Kleiner Perkins, Google Ventures, Coatue and Andreessen Horowitz among its investors, and its valuation has surged from three billion dollars in February two thousand twenty five to eight billion dollars by late October.
Harvey now serves seven hundred clients across sixty three countries, including most of the top ten law firms in the United States. The company also crossed one hundred million dollars in annual recurring revenue as of August.
The story began when Weinberg, then a first year associate at O Melveny and Myers, started using GPT three for routine legal tasks. He and Pereyra experimented with early chain of thought prompting and tested their results with practising attorneys who often approved the AI generated answers without edits. That early validation convinced them that legal workflows could be transformed.
A cold email to Sam Altman later opened the door to funding from the OpenAI Startup Fund, and the company quickly became one of the most talked about AI startups in the world.
Harvey is tackling complex challenges including ethical walls, data permissioning and real time collaboration across legal teams in dozens of countries. Weinberg says the goal is not to replace lawyers but to allow them to work faster, reduce errors and focus on higher level reasoning.
The company’s growth reflects both the rising valuation of AI startups and a clear demand within the legal industry for intelligent platforms that can handle contracts, analysis, discovery and research with greater speed.
Harvey continues to scale while shaping what many see as the future of legal technology.
