Aon Risk Solutions is a global risk advisory and insurance brokerage, led by CEO Greg Case, serving multinationals and institutions across 120+ countries.
Aon Risk Solutions
Aon Risk Solutions was founded in Chicago in 1919 by Patrick Ryan as Ryan Insurance Group, later renamed Aon in 1987. Greg Case has served as CEO since 2005, leading the firm through its transformation into a data-driven risk advisor. The firm provides insurance brokerage, risk management, and consulting services across property and casualty, employee benefits, cyber risk, and climate-related exposures. Aon operates in over 120 countries, with a client base spanning Fortune 500 corporations, government entities, and family offices. Key capabilities include analytics platform Aon Client Treaty, and placements in catastrophe bonds and parametric insurance. Aon employs roughly 50,000 professionals globally, with major offices in London, Chicago, and Singapore. The firm maintains the Aon Foundation for philanthropic giving and has engaged in climate resilience initiatives. In 2023, Aon completed the acquisition of Middle Market insurance broker NFP for $13.4B (per Aon, 2023), expanding its middle-market footprint. Aon's structural differentiator is its ownership of proprietary data and analytics: the firm runs one of the world's largest aggregations of corporate risk data, which it uses to model emerging threats like cyber and climate change at a scope few competitors match. This data advantage, combined with its independence from underwriters, allows Aon to act as an advisor, not a distributor.
