Harvey's 25,000 Custom Agents and Live M&A Due Diligence in Production

Harvey reported 25,000+ custom agents running in production on its platform, with M&A due diligence workflows generating 15–20% time savings on structured data rooms and up to 75% on unstructured document sets. GSK Stockmann and Bruchou & Funes de Rioja are running live M&A transactions on Harvey, and Microsoft's 2,000-person CELA legal department has deployed Harvey across legal and compliance operations. The scale of enterprise penetration — from a Nordic boutique to a Big Tech in-house team — illustrates the breadth of Harvey's current institutional footprint and explains the ARR trajectory. Heuking expanded Harvey to all professional groups firmwide on August 5. For legal tech operators tracking competitive dynamics, the most relevant signal is not the agent count but the shift toward use-case-specific custom agents as the primary adoption vector: firms are not buying a general-purpose AI tool but a portfolio of discrete workflow automations that happen to share infrastructure.
