CMS Expands Harvey Deal With Roll Out Across 50+ Countries

The platform wars continue. This time Harvey has scored a fresh win as CMS announces a firmwide roll out across all 21 CMS member firms in more than 50 countries, providing the legal AI productivity tech to over 7,000 lawyers and staff.

Before this expansion, Harvey was already used at CMS, they explained, with more than 1,100 daily active users and nearly 3,000 monthly users. But, the wider roll out to all 7,000 lawyers and staff follows ‘extensive collaboration between CMS and Harvey’.

They added that CMS will continue to ‘engage with a portfolio of generative AI tools to identify the most effective use cases and measure benefits’, i.e. more focused, point solutions that are narrow, but deep, will continue to be used.

In terms of why they chose Harvey, the firm said: ‘The adoption of Harvey has already demonstrated substantial benefits for CMS and its clients. Internal analysis shows that 93% of users have reported productivity gains equating up to 117.9 hours saved per lawyer per year.

‘The efficiency gains of using Harvey allow the firm to reduce write-offs, help reduce the load on lawyers, offer the most competitive prices to clients and maintain profitability.’

So, around 118 hours saved per lawyer annually – and that’s a lot relative to an associate’s billable targets. And interesting to see that they note both ‘competitive prices’ and also profitable work at the same time.

John Craske, Chief Knowledge and Innovation Officer at CMS UK, commented: ‘We are excited to expand our partnership with Harvey and for even more of our lawyers to use the platform. The adoption of generative AI tools across the firm has been remarkable and speaks volumes about our people’s appetite for innovation. This enthusiasm reflects our collective drive to stay ahead of the curve and deliver the highest-quality outcomes for our clients.’

Winston Weinberg, CEO of Harvey, said: ‘We are proud to have CMS as a long-standing customer of Harvey, and to see their decision to extend access to all of their lawyers and team members. Their commitment to scaling Harvey reflects true leadership in innovation. We’re proud to support CMS as they redefine how AI enhances legal practice worldwide.’

And, Jane Challoner, CMS Director of Innovation, Knowledge and Learning, concluded: ‘At CMS, we are focused on innovating to make a real difference for our clients. Rolling out Harvey across the firm brings generative AI into the core of how we work—helping our lawyers not just save time but amplify their expertise and human insights. That means our global teams can focus on what really matters: tackling complex challenges and delivering outstanding results for our clients around the world.’
