What Is Harvey AI?
Harvey AI was founded in 2022 by Winston Weinberg (a former securities attorney at O'Melveny & Myers) and Gabriel Pereyra (a former Google DeepMind researcher). The company builds AI tools trained specifically for legal work — not general-purpose chatbots adapted for law, but purpose-built models that understand legal reasoning, citation standards, jurisdictional nuances, and professional ethics.
Harvey has raised over $200 million in funding from investors including Sequoia Capital and Google Ventures, reaching a $2 billion valuation. The platform is used by some of the world's largest law firms and professional services firms for contract drafting, legal research, due diligence, regulatory analysis, and litigation support.
What sets Harvey apart from using ChatGPT or Claude for legal work is its training data and safety guardrails. Harvey's models are fine-tuned on legal corpora, understand citation formats, can identify potential conflicts of interest, and are designed to refuse tasks that would constitute unauthorized practice of law. The platform also maintains strict data isolation — one firm's data never trains models used by another firm.
