Harvey
AI tools for legal and professional-services work — contract review, due diligence, research and drafting — sold mainly to large law firms.
Harvey is a US company, founded in 2022 by former lawyer Winston Weinberg and former DeepMind and Meta researcher Gabriel Pereyra, that builds AI tools for legal and professional-services work — contract analysis, due diligence, research and drafting. An early recipient of investment from the OpenAI Startup Fund, it sells mainly to large law firms and corporate legal departments, and reported rapid growth in recurring revenue. Its valuation rose steeply through 2025 and into 2026, reaching a reported $11bn, making it one of the most highly valued companies applying AI to a single profession.
