Aon plc

Aon plc is a global professional services firm focused on helping organizations make decisions about risk and people. Its business is organized around two main platforms: Risk Capital, which covers insurance brokerage, risk consulting, captives and affinity programs, and Human Capital, which covers health, wealth, talent and related advisory services. The company uses analytics, data and a globally connected operating model to design solutions that are tailored locally but delivered through a unified platform. Aon serves clients in more than 120 countries and emphasizes recurring, capital-light advisory and brokerage revenue rather than balance-sheet-intensive underwriting.
