Slaughter and May Rolls Out Harvey AI Across All Practice Areas

Slaughter and May is deploying Harvey’s AI platform across the firm after extensive evaluation.

Slaughter and May, one of the UK's Magic Circle law firms, has adopted Harvey’s artificial intelligence platform across all practice areas after a rigorous review of its capabilities.

• The deployment aims to support legal work in areas like M&A, due diligence, regulatory research, and document analysis, with a focus on enhancing client service delivery.
• Managing Partner David Johnson said, “Adopting Harvey firmwide allows us to enhance the excellent service that we provide to our clients. Critical to our adoption is the investment we make in our people, as the vital human layer that supervises AI.”
• Sally Wokes, Head of the Innovation Committee, emphasized that AI “allows us to connect and apply [our] expertise in different situations, enhancing the collective judgment, creativity and problem solving we bring to client matters.”
• Harvey’s agentic features, security profile, and legal sector experience were cited as decisive factors for the rollout. The platform is now in use with over 1,300 customers in 60 countries, including most Am Law 100 firms, according to PYMNTS.com.
• Other Magic Circle firms, notably Allen & Overy, have also embraced Harvey’s solution, showcasing a broader push among top-tier practices toward advanced legal technology adoption.

Winston Weinberg, CEO of Harvey, noted the significance of pairing longstanding legal expertise with new technology to address critical legal work globally. Harvey has raised over $1 billion and is now valued at $11 billion as of March 2026.
