Harvey
AI for legal professionals
About Harvey
Harvey is an AI platform designed specifically for the legal industry. Founded by Winston Weinberg (former antitrust attorney) and Gabriel Pereyra (former Google DeepMind researcher), Harvey applies large language models to legal work — contract analysis, legal research, due diligence, litigation support, and regulatory compliance.
The platform is used by elite law firms including Allen & Overy, A&O Shearman, and other Am Law 100 firms. Harvey's models are fine-tuned on legal data and designed to handle the precision, citation requirements, and confidentiality demands of professional legal work.
Harvey represents the vertical AI category — building domain-specific AI for a regulated industry where general-purpose tools aren't sufficient. Legal work requires accuracy standards, citation practices, and confidentiality guarantees that generic LLMs cannot provide out of the box.
