AIG taps Seraina Macia to lead technology unit

American International Group Inc. on Thursday said it has appointed Seraina Macia executive vice president and CEO of the insurer’s planned technology subsidiary focused on automated underwriting, returning the executive to the company she left in early 2016.

Ms. Macia will report to AIG President and CEO Brian Duperreault and serve on the company’s executive leadership team, AIG said in a statement.

She was previously CEO of Hamilton USA, the U.S. platform of Hamilton Insurance Group Ltd., which is to be acquired by AIG, according to an announcement May 15. The new appointment will return her to the helm of that unit following the acquisition’s completion, expected in the fourth quarter of 2017.

Prior to that, she had left AIG during a management reorganization under former CEO Peter Hancock.

Ms. Macia’s role will include the continued development of Attune, the data and technology joint venture formed last year by AIG, Hamilton and Two Sigma Investments L.P., which is aimed at the $150 billion small commercial insurance segment, according to the statement.

“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,” Mr. Duperreault said in the statement.

“With AIG’s purchase of Hamilton’s U.S. platform, we are poised to transform how our industry operates in a digital world,” Ms. Macia said in the statement.

Ms. Macia (formerly Maag) was one of the Business Insurance Women to Watch in 2009.
