AIG appoints Hamilton USA CEO as boss of upcoming tech subsidiary


American International Group (AIG) has appointed Seraina Macia as executive vice president and chief executive officer (CEO) of a new planned subsidiary that aims to transform the way that AIG delivers and underwrites commercial insurance.

Macia will report to AIG president and CEO Brian Duperreault, and serve on the company’s executive leadership team.

On May 15, AIG announced its intention to acquire Hamilton USA, the US platform of Hamilton Insurance Group, to continue accelerating AIG’s application of emerging technology and data science to transform underwriting and claims.

Following the acquisition’s completion, which is expected in the fourth quarter of 2017, Macia will lead the newly acquired platform. She will also play an integral role in the accelerated development of Attune, according to the statement. Attune, the data and technology-driven joint venture formed last year by AIG, Hamilton and Two Sigma, focuses on the $150 billion small commercial insurance segment.

Macia joins AIG from Hamilton USA, where she served as CEO since 2016. Prior to this, she held executive positions at AIG, including CEO and executive vice president of regional management and operations, and was a member of AIG’s executive leadership team. Prior to this, she was CEO and president of AIG’s EMEA region, with responsibility for 47 countries across Europe, the Middle East and Africa.

Duperreault said: "Seraina brings to AIG a rare combination of deep insurance expertise and an acute understanding of the role that technology and data analytics are playing in the ongoing evolution of our industry. Her perspective will be a valuable one to have on our leadership team."

Macia added: "It is great to be returning to AIG in this exciting new role. Brian has a clear vision for the future of insurance and for AIG. I’m looking forward to building on the progress we made at Hamilton USA in bringing technology and data analytics to risk selection, pricing and claims-handling processes.

"With AIG’s purchase of Hamilton’s US platform, we are poised to transform how our industry operates in a digital world and how we meet the needs of our clients. I look forward to being part of expanding and growing AIG during this next chapter in its history."

Prior to joining Hamilton USA, Macia was the CEO of XL Insurance North America, president of Zurich North America commercial specialties business, and head of investor relations and rating agency management of Zurich Insurance Group.
