Harvey is the frontier legal AI platform built specifically for Big Law and enterprise legal work. Founded in 2022 and now valued at $11 billion after its $200M March 2026 round, Harvey is used by over 100,000 lawyers across 1,300 organizations including A&O Shearman, Gibson Dunn, and DLA Piper.
Core capabilities span the full spectrum of high-end legal work: legal research, complex contract analysis, M&A due diligence, regulatory compliance, and multi-step agentic workflows. Harvey's models are fine-tuned on legal data — not generic AI with a legal label — and integrate directly into the workflows attorneys already use, including Microsoft 365, document management systems, and practice management tools via strategic partnerships.
Best fit: AmLaw 100 firms, Magic Circle firms, and large enterprise legal departments running high-volume diligence and regulatory work. The enterprise pricing (estimated $1,000-1,200/seat/month) and procurement process align with that scale.
Harvey is the category-defining premium legal AI platform. Where Spellbook owns the productivity middle market and CoCounsel/Lexis+ anchor on research depth, Harvey owns the frontier-model, agentic-workflow tier. As of 2026, no other player matches Harvey's funding, customer roster, or scope.
