Harvey closed $550M co-led by Lightspeed and Diffusion at a $15.5B valuation on September 9, crossing $400M ARR with 3,000+ customers including 80% of the AmLaw 100 and half the Fortune 10, bringing total raised past $1.5B. On the September 11 20VC x SaaStr episode, Rory O'Driscoll argued the category is structurally capped: a $10-12K per-lawyer subscription against a $200K salary is 5-10% of spend, versus 30-50% in coding, putting the addressable market at $30-60B of a $300B legal services market. The pairing is the sharpest available read on whether vertical AI SaaS multiples survive contact with seat economics.
