With Allen & Overy, PwC, and 100+ elite law firms deploying Harvey, the platform has achieved product-market fit faster than any legaltech product in history. As junior associates burn out on document review and clients demand lower fees, Harvey's AI co-pilot offers a win-win: lawyers focus on strategy, clients pay less, firms improve margins. If Harvey can reach $1B+ ARR by 2028, maintain its technical lead (via OpenAI partnership), and expand globally, the company could achieve a $10-30B public valuation and challenge Thomson Reuters and LexisNexis as the platform for legal work. **The question isn't whether AI will transform law—it already is. The question is whether Harvey will be the platform that every lawyer uses—and $1.5B at 18 months suggests investors believe the answer is yes.**
