Marsh McLennan launches AI tool LenAI

Marsh McLennan, a New York headquartered professional services firm, on Tuesday announced the launch of a new generative AI tool – LenAI.

Co-developed by Marsh McLennan’s Dublin innovation center and Oliver Wyman – its management consulting subsidiary – the tool will be used by Marsh McLennan’s more than 85,000 professionals globally.

LenAI is built on Microsoft and OpenAI technologies, and uses a private, internally hosted version of OpenAI’s models to keep all data in-house. Marsh McLennan says its compliance, IT, and legal teams partnered closely on the project to ensure strict standards for data security.

Early adopters at Oliver Wyman have self-reported saving an average of eight hours a week when using the tool, including spending 20% less time on simple, repetitive tasks.“We have some of the brightest minds in business working across our four businesses and a collaborative culture,” said Paul Beswick, SVP and global chief information officer, Marsh McLennan. “When it came time to introduce the tool, we were able to deploy it quickly and securely. Since its full launch recently, LenAI has been a game changer for our teams, enabling them to work smarter for the benefit of our clients.”

Oliver Wyman has worked on numerous projects to help clients leverage AI to boost productivity and efficiency and manage risk related to deploying AI solutions. The consultancy has developed bespoke tools including project management platforms, customer personalization engines, and social listening analytics suites.

OpenAI, the technology startup leading the generative AI wave, had a tumultuous past week. On Friday, the company’s board fired CEO Sam Altman, citing a lack of confidence. In the days following, Altman was given an AI leadership role at major investment partner Microsoft, while most of OpenAI’s 800-person workforce threatened to quit if Altman was not reinstated.

On Wednesday, most of OpenAI’s board resigned and Altman returned as CEO.
