Updated June 15, 2026Harvey AI is a legal AI platform founded in 2022 by Winston Weinberg (former associate at O'Melveny & Myers) and Gabriel Pereyra (former Google DeepMind researcher). The company has raised over $200 million and is valued at approximately $3 billion, making it one of the most valuable AI-native legal technology startups.
Harvey's platform is designed specifically for legal professionals, with AI capabilities trained on legal data and optimized for legal workflows. The system can draft contracts, analyze documents, conduct legal research, summarize depositions, and assist with due diligence — tasks that traditionally require hundreds of billable hours. Harvey's AI understands legal concepts, jurisdictional nuances, and professional standards in ways that general-purpose AI tools cannot match.
Harvey has been adopted by several of the world's largest law firms, including Allen & Overy (the first to announce firm-wide deployment), as well as professional services firms like PwC. The platform represents the leading edge of AI transformation in the legal industry — one of the most knowledge-intensive and expensive professional services sectors, where AI-driven efficiency gains can translate directly into competitive advantage.
