Marsh McLennan has launched a new Generative AI tool called LenAI for its 85,000 global workforce, and says staff are reporting savings of eight work hours a week on average, and 20% less time spent on simple and repetitive tasks. 

Len AI is built on Microsoft and OpenAI technology, using an internally hosted version to keep data private.  

The low-cost, secure environment aids problem solving and experimentation, and is summarising meetings, extracting key data from documents, and writing drafts of emails and presentations. It can search the internet, perform accurate calculations, and access information from publications. 

“LenAI has been a game changer for our teams, enabling them to work smarter for the benefit of our clients,” Marsh McLennan Global CIO Paul Beswick said.  

“The opportunities to streamline processes and expedite time-consuming tasks will only continue to grow in the future.” 

Private capital teams at consulting arm Oliver Wyman are using LenAI to streamline digital intelligence work for private equity firms, Head of Digital Americas Vivek Sen says. 

“So much of what our case teams do relies on rapid ingestion of vast amounts of data, including client and internal data, as well as first drafts. So LenAI has been a game-changer,” he said.
