The Raise
Harvey AI closed a $500M Series D round led by Sequoia Capital with participation from Google Ventures, Kleiner Perkins, and strategic investors including Allen & Overy and Kirkland & Ellis. The round values the company at $5 billion — a 3.5x increase from its $1.4B Series C just nine months ago.
Traction
Harvey has achieved remarkable enterprise adoption:
- 200+ law firms on the platform, including all Big Four professional services firms
- 50,000+ lawyers actively using the tool daily
- $120M ARR, up from $35M a year ago — a 3.4x growth rate
- Expanded from contract review to litigation, regulatory compliance, and M&A due diligence
Product Expansion
Harvey announced three new products alongside the funding: Harvey Litigation (case law research and brief drafting), Harvey Regulatory (real-time regulatory change monitoring), and Harvey M&A (automated due diligence workstreams). Each is trained on domain-specific legal corpora with firm-specific fine-tuning.
We're building the operating system for legal work. Every lawyer will have an AI teammate within three years. — Winston Weinberg, CEO of Harvey AI
Market Impact
The legal AI market is now estimated at $3.2B annually and growing 45% year-over-year. Competing platforms like CoCounsel (Thomson Reuters) and Luminance reported similar growth trajectories, suggesting the entire sector is reaching an inflection point.
