Charles Russell Speechlys adopts Harvey after structured five-vendor head-to-head evaluation
Charles Russell Speechlys (CRS) ran a structured two-week, five-vendor head-to-head AI evaluation with 46 lawyers (trainees to partners), generating 7,000 structured data points across real (non-confidential) case work. The exercise — prompted by the March 2025 acquisition of its former custom-AI vendor Springbok AI by US firm Cleary Gottlieb — found that legal competence and conceptual understanding mattered more than speed, and that Harvey was the clear top performer across all task categories. CRS has since used Harvey on a Swiss Basketball regulatory overhaul, a workplace harassment investigation, and preparation for a criminal fraud trial. The firm published its methodology and findings publicly in partnership with TLW Consulting.
