Overview
- A funding round announced Wednesday, September 9, raised $550 million and values Harvey at roughly $15.5–15.6 billion according to company disclosures and multiple reports.
- Harvey acquired Guardrails AI as part of the announcement and said the deal brings Guardrails’ reliability and agent‑security engineers into its product and engineering teams.
- The company says annual recurring revenue has passed $400 million and that it now serves more than 3,000 customers, including about 80% of the Am Law 100.
- Harvey has begun shifting from renting third‑party models to running its own post‑trained legal models, shipping Tenet in August on Moonshot AI’s open‑weight Kimi K3, a choice that raises documented questions about model provenance and where client work’s documentation chain begins.
- Investors see a large market opportunity in legal AI but the valuation multiple, heavy hiring and move to in‑house models create new dependencies and competitive pressure from major model providers that could shape Harvey’s strategy and client risk profile.
