Harvey, a leading provider of generative AI solutions for the legal industry, is proud to announce that Hengeler Mueller, one of Europe’s most prestigious law firms, has renewed their agreement and chosen to go firmwide with Harvey. All Hengeler Mueller employees will receive access to Harvey, reinforcing the firm’s commitment to innovation and its investment in equipping lawyers at every level with the most advanced tools to serve clients.

Harvey enables Hengeler Mueller’s lawyers to quickly and accurately perform legal tasks such as contract review, due diligence, legal research, and regulatory compliance while keeping client data private and secure.

Prior to this expansion, the demand among lawyers to use Harvey far exceeded the available seats. “To enable the use of secure, controlled AI, we are delighted to have agreed with Harvey that all our employees will receive access. After seeing high usage and adoption throughout our engagement, there was demand from our team to go firmwide with Harvey,” said Hengeler Mueller partner Andreas Hoger.

Harvey being available to everyone across the firm ensures that Harvey not only supports client work but also strengthens career development. All lawyers and staff are trained in its use, giving even junior lawyers the chance to gain early experience with advanced legal tech. By building AI fluency from the very beginning, Hengeler Mueller’s next generation of lawyers are learning to use cutting-edge technology effectively and with an innovative mindset.

Commenting on the decision, Hengeler Mueller partner Dr. Fabian A. Quast said: “Our young talents have the opportunity to gain early experience with legal tech tools and also familiarise themselves with Harvey through our intensive training sessions.”

Harvey CEO Winston Weinberg said: “We are honored to partner with Hengeler Mueller, a firm renowned for its excellence in complex transactional and regulatory matters. Their decision to extend Harvey access to every employee demonstrates a remarkable commitment to both innovation and talent development. We look forward to supporting Hengeler Mueller as they set the standard for the thoughtful adoption of legal AI across Europe.”

Hengeler Mueller’s decision follows a rigorous process to ensure the firm could deploy Harvey responsibly and effectively. By granting firmwide access, Hengeler Mueller underscores that the benefits of AI are not only for client service but also for professional development, giving young lawyers the opportunity to master next-generation tools from the outset of their careers.
