AIG has appointed Seraina Macia new executive vice president and CEO of a planned technology subsidiary intended to modernize the way the carrier underwrites commercial insurance through data science.

Macia previously served as CEO of Hamilton USA, part of Hamilton Insurance Group, before AIG acquired the company on May 15. The insurance veteran will lead the newly-purchased business unit after the deal closes in the fourth quarter, and work toward accelerating AIG’s adoption of analytics to enhance underwriting and claims practices.

Additionally, she will play a pivotal role in the development of Attune, the data-driven joint venture formed last year by AIG, Hamilton and Two Sigma, which focuses on the $150 billion small business insurance market. Macia will report to former colleague and AIG CEO Brian Duperreault.

“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,” said Duperreault, former chairman & CEO of Hamilton Insurance Group, in a statement. “Her perspective will be a valuable one to have on our leadership team.”

Other notable jobs throughout her career include CEO of XL Insurance North America, president of Zurich North America’s commercial specialties business as well as a number of underwriting and finance roles at Swiss Re in the 1990s.

“Brian [Duperreault] 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,” said Macia. “With AIG’s purchase of Hamilton’s U.S. platform, we are poised to transform how our industry operates in a digital world and how we meet the needs of our clients.”
