Marsh McLennan

Marsh McLennan lives in the world of insurance brokerage, risk consulting, and benefits advice, which means its real customers are companies and institutions rather than ordinary shoppers. By our assessment, its strength is breadth: it combines brokerage with consulting through names like Marsh, Mercer, Guy Carpenter, and Oliver Wyman, so it can handle several kinds of corporate risk work under one roof. The downside is that this kind of business is naturally opaque to outsiders, and most of its value shows up in contracts, advice, and specialist relationships rather than in a product you can picture on a shelf. In practice it is a steady, paperwork-heavy kind of company, closer to the back office of business than to a visible consumer brand. Compared with a simple broker, it sits higher up the chain because it mixes advice with placement and management of risk. The US code fits that profile. It is for organizations that need serious insurance and consulting machinery, not for anyone looking for a quick, obvious service.
