Harvey, operated by Counsel AI Corporation, is a San Francisco-based legal AI company founded in 2022 by Winston Weinberg, a former securities and antitrust litigation associate, along with Gabriel Pereyra. The company's platform provides AI tools purpose-built for legal work, including document review, research, and drafting assistance, and is used by major law firms and corporate legal departments navigating the specific accuracy and confidentiality requirements of legal practice.
Harvey reached a valuation of approximately $11 billion during 2026, and acquired legal technology company Hexus in January 2026 to expand its capabilities as competition in the legal AI category intensified. CEO Winston Weinberg has spoken publicly about building the company through rapid iteration and learning from early product failures, and the company has increasingly framed its positioning around AI becoming core infrastructure for legal work rather than an experimental add-on.
