In early 2015 Marsh & McLennan Companies named him chairman of MMC's Risk & Insurance Services segment, which included both Marsh and Guy Carpenter. In this capacity he led teams providing risk advice and capital solutions to companies in around 130 countries.

Together with Duperreault, Zaffino developed AIG's long-term strategy and operating plan.

He also continued to lead the firm's General Insurance unit as CEO until August 2020, and then transitioned to focus more on enterprise-wide leadership responsibilities in his role as president and global COO.

Zaffino heads AIG 200, a multi-year, company-wide operational overhaul and modernization plan announced in 2019. The name "AIG 200" refers to the second 100 years for AIG, which was founded in 1919.
