Marsh scales internal AI tools to a million prompts weekly
Marsh says it rolled out LenWork to 27,000 people within weeks and that internal AI usage data is now used to guide where the firm invests.
Insurance brokerage Marsh is expanding the use of its in-house generative AI, describing an adoption curve that has accelerated from thousands of monthly prompts to about a million prompts per week. Insurance Business reports that Marsh McLennan COO Puneet Satyawadi said the firm made a deliberate effort to put its proprietary tools in front of every employee across more than 80 countries.
Marsh built LenAI through the Dublin Innovation Center, partnering with Oliver Wyman, and it runs a private, internally hosted version of OpenAI models. Satyawadi said the company saw early hesitation fade after training and the rollout of completion badges, and he pointed to usage growth as the sign the approach is working.
The firm has also launched LenWork, a newer platform, reaching 27,000 people within weeks, and employees have built about 2,000 reusable capabilities within LenAI for similar job profiles, up from roughly 1,800 a month earlier. Insurance Business adds that Marsh’s internal innovation group uses this behavioral data to shape funded investments, treating observed usage patterns as planning inputs.
Separately, Marsh is scaling a coverage intelligence platform in which more than 3,000 colleagues query a structured repository of claims data to evaluate carrier performance and to help steer placement. Insurance Business reports that Satyawadi said the broker’s scale provides more data than rivals, and that equipping client-facing teams to analyze it is a differentiator.
