The report covers 40 customers, 29 law firms and 11 corporate legal teams. Study participants were drawn from North America, Europe, UK, APAC and Latin America. They represented a broad cross-section of users, big and small organisations, mature and newer users, full enterprise licenses to firms with fewer licenses.

Law firm participants included: A&O Shearman, ArentFox Schiff, Ashurst, Cuatrecasas, Gilbert + Tobin, Honigman LLP, Jackson Walker, King & Wood Mallesons, Lewis Silkin LLP, Lynn Pinker Hurst & Schwegmann LLP, Machado Meyer, Mayer Brown LLP, Mori Hamada, Orrick, Paul Weiss, Rajah & Tann Singapore LLP.

In-House participants included: ArcelorMittal, AT&T, Centros Comerciales Carrefour S.A., National Grid, Repsol, Syngenta Group, Talanx.

“I was surprised at how quickly Harvey has become part of a lawyer’s everyday working life and the emotive responses we received about how much they value its ability to enable them to do higher value work. I did not expect this impact to evince itself so quickly,” says Reena SenGupta, RSGI’s Executive Director.

“The report shows how legal AI adoption has moved well beyond the pilot phase and is embedded in daily workflows,” says K-Ming Lee, Head of Customer Engagement at Harvey. “We wanted to provide evidence-based insight into Harvey’s measurable impact and the report highlights how our customers are shaping the future of the legal industry.”
