🔗 Visit Harvey
Description
Large law firms handle an enormous range of legal work — research, drafting, contract review, due diligence — much of it spread across many different specialized tools and a lot of it done manually by junior lawyers under time pressure. Harvey was built to be a single AI platform that spans that whole range, rather than solving just one narrow piece of it, which is why the majority of the largest, most prestigious U.S. law firms have adopted it. Harvey covers document analysis and drafting (Harvey Assistant), secure bulk document storage and analysis (Vault), legal and regulatory research (Knowledge), end-to-end workflow automation (Harvey Agents), deal analysis and contract review (Contract Intelligence), and cross-organization collaboration (Shared Spaces), with a mobile app and analytics dashboard (Command Center) rounding out the platform. It's reached an $11 billion valuation as of its March 2026 round, backed by Sequoia, Kleiner Perkins, Google Ventures and the OpenAI Startup Fund, and reports over 70 Am Law 100 firms and 2,400+ customers across 70+ countries.
💬 Our review
The short version: Harvey has become close to the default AI platform at the largest U.S. law firms specifically because it covers the whole breadth of legal work — research, drafting, contract analysis, workflow automation — rather than one narrow slice, and its $11B valuation and Am Law 100 adoption rate reflect that it's winning the broad-platform bet at the top of the market.
The breadth itself is the real differentiator versus a specialist tool like Spellbook: a large firm doing research, litigation support, M&A due diligence and contract work all at once benefits from one integrated platform rather than stitching together several point tools, and "Vault" (secure bulk document analysis) plus "Shared Spaces" (cross-team collaboration) are specifically built for the scale and confidentiality requirements of large-firm work. Backing from the OpenAI Startup Fund alongside top-tier VCs (Sequoia, Kleiner Perkins) is a strong signal of both capital and AI-model access advantages relative to smaller competitors. The honest trade-off: this breadth and scale come with enterprise-only, fully custom pricing that's realistically out of reach for a solo practitioner or small firm — Spellbook is the more accessible, contract-focused option at that end of the market. As with any vendor's own numbers, Harvey's usage statistics (200,000+ legal professionals, 25+ hours saved per user monthly) are self-reported and worth treating as directional rather than independently audited, though its adoption among a majority of Am Law 100 firms is itself a meaningful, harder-to-fake signal of real usage at the top of the legal market.
