Score methodologyDomain-tuned AI for law firms: research, drafting, diligence, and agentic legal work.
Harvey sells specialized AI to the least forgiving software buyers in professional services: more than 100,000 lawyers across 1,300-plus organizations in 60-plus countries use it for research, drafting, and multi-step agentic workflows like diligence review. Built on OpenAI models — the OpenAI Startup Fund was an early backer — it reached an $11 billion valuation on a $200 million round co-led by GIC and Sequoia, making it legal tech's biggest venture bet.
Best for
Big Law and sophisticated in-house teams with the matter volume and billable rates to absorb reported four-figure monthly seat costs. Firms wanting a cheap per-seat experiment should look elsewhere — reported 20-seat minimums and annual commitments make Harvey an institutional purchase.
Thomson Reuters' CoCounsel arrives bundled with Westlaw's research authority; Spellbook undercuts on price for contract work inside Word. Harvey's counter is workflow depth — agentic multi-document diligence, matter workspaces, firm-specific tuning — plus the credibility of being the platform elite firms standardized on first, with industry reporting putting adoption at about half the Am Law 100. It behaves like a professional-services platform, not a chatbot with a legal system prompt.
