WTW (Willis Towers Watson) is a global professional services firm operating across two main businesses: insurance brokerage and human capital consulting. In insurance brokerage, WTW acts as an intermediary between corporate clients and insurance carriers — placing coverage on behalf of clients and earning commissions or fees without taking on insurance risk itself. The core brokerage unit, Corporate Risk & Broking, places more than $34B of annual premiums across specialty lines including property & casualty, construction, aerospace, marine, financial lines, and natural resources. A smaller unit, Insurance Consulting & Technology, provides actuarial consulting and analytics software to insurance carriers. In human capital consulting, WTW advises large employers on health benefits, retirement programs, and compensation. This includes consulting and brokerage for employer health plans, actuarial work for defined benefit pension funds, investment advisory, compensation benchmarking, and benefits administration outsourcing. WTW's clients are primarily large multinationals — roughly 93% of the FTSE 100 and 89% of the Fortune 1000. The company operates through two segments: Health, Wealth & Career (~55% of revenue) and Risk & Broking (~45%). HWC is heavily recurring, driven by long-term consulting relationships and multi-year outsourcing contracts. R&B revenue is tied to premium volumes and the insurance pricing environment. WTW's growth strategy centers on specialty broking expansion, cross-selling across HWC, and ongoing efficiency improvements through centralized delivery and automation.
