CMS reaches 95% Harvey adoption across 3,000+ lawyers

CMS, one of the world's largest international law firms, faced the challenge of integrating generative AI into its legal practice to remain competitive and meet evolving client expectations. The firm needed a secure, legal-specific AI platform that could be practically applied to real workflows, moving beyond a simple tool to a fundamental transformation in how its 7,200 lawyers work. They partnered with Harvey to implement its AI platform to enhance document analysis, research, and drafting.

The solution from Harvey was implemented as a firmwide transformation program, focusing on practical enablement and embedding the AI into daily workflows like contract review, knowledge synthesis, and large-scale document analysis. The results were exceptional, achieving 95% adoption across 3,000+ lawyers during the initial rollout. This scaled into one of the largest GenAI deployments in legal, allowing lawyers to review larger document sets faster and unlock new types of work, making AI a daily habit at CMS.
