Harvey is a domain-specific AI platform built for legal and professional services work, designed to handle complex, end-to-end legal tasks that general-purpose chatbots cannot. Founded in 2022 and trained on legal-specific data, Harvey combines frontier language models with a deep legal content layer to support research, drafting, due diligence, and contract analysis at firm scale. Its product suite is organized around Harvey Agents, which execute multi-step legal work autonomously, alongside Assistant for document analysis and drafting, Vault for secure storage and bulk analysis of up to 100,000 documents, Knowledge for legal, regulatory, and tax research, Contract Intelligence for negotiation support, and a Command Center for analytics and benchmarking. Through a strategic alliance with LexisNexis, Harvey's Ask LexisNexis feature returns citation-backed answers grounded in U.S. federal and state case law, while a Microsoft 365 Copilot integration lets lawyers invoke Harvey directly inside their existing workflow. More than 25,000 custom agents run on the platform across M&A, due diligence, contract drafting, and document review. As of 2026, Harvey is used by over 142,000 lawyers across 1,500+ customers in 60+ countries, including roughly half of the Am Law 100, and the company raised $200 million at an $11 billion valuation in March 2026. Harvey targets large law firms and enterprise legal and tax teams that need accuracy, security, and citation-backed outputs rather than consumer-grade convenience.
