Guy Carpenter has appointed Dorothee Melis-Moutafis as head of global clients at a moment when the reinsurance broking market is under structural pressure and the battle for client relationships is intensifying. The role puts her in charge of coordinating reinsurance strategy and client support across the broker's international operations from a single group-level function.
Melis-Moutafis brings 25 years of European reinsurance broking experience to the position. She has been with Guy Carpenter since 2013. She joined as managing director of the Property Solutions Group, responsible for France, Iberia, Italy, Greece, and Turkey. Her most recent role was executive vice president for executive partnership and C-suite engagement.
Before Guy Carpenter, she spent 15 years at Willis Re. She progressed from broker to divisional director overseeing the London desk for Iberia and southern Europe, and later held executive director roles covering the London desks for France and Iberia. In 2012 she became executive director and management board member of Willis Re France and Willis Re Iberia.
The global clients function has been a priority for some time. In July 2025, Guy Carpenter hired Matthew Flynn to lead global client strategy within its Global Specialties division.
The Melis-Moutafis appointment takes that model further. She will oversee the broker's largest client relationships at group level rather than within a single business line, with the role sitting at the intersection of major cedents and the specialist teams serving them across regions and product lines.
The scope of that task has expanded as reinsurance structures have grown more complex. Guy Carpenter's own research, published in May 2026, placed alternative capital at close to 20% of the global reinsurance pool, estimated at US$660 billion. Cat bond issuance reached roughly US$25 billion in 2025, with US$58 billion outstanding in 144A bonds. Managing client access to both traditional and capital markets capacity across multiple business units is the practical challenge the new function addresses.
The appointment also arrives against a difficult competitive backdrop for Guy Carpenter. Willis Re drew roughly 80 professionals from Guy Carpenter between mid-2025 and mid-2026, spanning property retrocession, specialty lines, analytics, and life reinsurance across London, Bermuda and Asia.
A High Court judgment in February 2026 found that two former Guy Carpenter executives improperly assisted Willis Re's hiring push before resigning. Financial damages were deferred to a later stage of proceedings.
Guy Carpenter has responded with a series of structural changes. In late June 2026, the broker merged its UK and London Europe P&C teams under a single leader, framing the move as an effort to sharpen its position across property, specialty and emerging risk areas. The Melis-Moutafis appointment sits within the same wave of reorganisation, in a market where the top four reinsurance brokers collectively hold around 90% of global business.
