Arthur J. Gallagher & Co. (AJG) is one of the largest global insurance brokers, with a strong presence in retail brokerage, employee benefits, and risk management services. The company has grown through a mix of acquisitions and organic expansion, competing with large global brokers such as Marsh McLennan, Aon, and Willis Towers Watson, while also facing regional and specialist brokers in fragmented local markets. You are interviewing for a strategy role supporting AJG's brokerage business in North America.
AJG's leadership wants to accelerate growth in the middle-market commercial insurance brokerage segment over the next 24 months. The segment is attractive because it is large, fragmented, and still relationship-driven, but pricing pressure, carrier consolidation, and digital-first competitors are increasing. AJG must decide where to focus: deepen penetration in its existing core industries, expand into underpenetrated geographies, or build a more digital-led go-to-market motion for smaller middle-market clients.
The question is not whether insurance brokerage is attractive in general, but how AJG should win in this market and why the brokerage model remains valuable despite technology disruption.
