Aon acquires Hewitt Associates (2010)
Aon, the insurance brokerage, bought Hewitt Associates, one of the largest HR consulting and benefits administration firms, in a multibillion-dollar deal. The combination, renamed Aon Hewitt, paired high-margin consulting advice with lower-margin outsourcing operations.
Aon Hewitt became a leading HR services provider, but the outsourcing business ran on thinner margins than consulting.
Aon sold the HR outsourcing arm to private equity firm Blackstone in 2017; it now operates as Alight. The combination was profitable but eventually unwound.
Korn Ferry is pairing consulting with AMS's recruitment outsourcing, a similar mix of two business models with different economics.
