Moussa Thiam, Group Head of Compliance at Hamilton

This appointment underscores Hamilton’s continued focus on strengthening governance and regulatory oversight as a publicly listed company, and recognises Thiam’s significant contributions since joining Hamilton in December 2024.

In his new role, Thiam will lead and coordinate compliance activities across Hamilton’s global operations, ensuring consistent standards and a unified approach across its underwriting platforms. Based in London, he will report to Gemma Carreiro, Group General Counsel, and will work closely with senior leadership and teams across the organisation to further embed compliance into day-to-day decision-making and support the Company’s strategic ambitions.

Commenting on the appointment, Carreiro said, “We operate in an increasingly complex and interconnected regulatory landscape where maintaining strong standards of compliance is a fundamental component of how we do business. Establishing this group-wide role reflects both the scale of our business today and reinforces our commitment to upholding the highest standards of compliance and governance globally as we support sustainable, responsible growth.

“Moussa has made a significant impact since joining Hamilton and is a trusted, collaborative leader. This promotion recognises his deep understanding of our business and his ability to work effectively across teams and regions to build a strong, practical compliance culture.”

Thiam joined Hamilton as Head of Compliance for the Company’s Hamilton Global Specialty and Hamilton Re underwriting platforms and has worked extensively across the business on key compliance and regulatory initiatives. He previously served as Head of Cross-Border & International Compliance at Beazley for seven years and before that held several compliance and regulatory advisory roles at MS Amlin, Financial Ombudsman Service and Lloyd’s Banking Group.
