Pine Walk, the specialist managing general agent (MGA) platform of The Fidelis Partnership (TFP), launches Mezura Capital Partners (Mezura Capital), a new capital solutions business. Headquartered in Bermuda, Mezura Capital focuses on delivering strategic capital solutions and partnerships for insurers and reinsurers. Its offering includes whole account solutions, structured casualty and specialty arrangements, and retrospective solutions, including combined prospective and retrospective covers. The new business is led by Shireen Gammoh as CEO. She joins from Howden Re, where she served as managing director in its legacy and structured solutions team. Gammoh brings nearly two decades of experience across Bermuda, London and the US, with expertise in retrospective, structured reinsurance, and capital solutions, as well as alternative and insurance-linked securities (ILS) capital market solutions. Prior to her time at Howden Re, Gammoh was global head of capital advisory at Gallagher Re, and she also held senior capital management positions at Flood Re and Canopius. With the launch of Mezura Capital (subject to receipt of necessary regulatory approvals), Pine Walk has now established 17 businesses on its platform. Founded in 2017, the platform provides custom underwriting, operational and regulatory frameworks to support specialist and innovative underwriting offerings. In 2025, Pine Walk grew its gross written premium to US$1 billion. Michael Davern, UK chief underwriting officer and group head of D&F property and energy at The Fidelis Partnership, says: “Pine Walk is a key pillar of TFP’s differentiated distribution footprint and we’re delighted to launch Mezura Capital as Pine Walk’s 17th business unit.” He adds: “In a global risk environment evolving at pace, there is increasing demand for flexible, innovative and tailored capital solutions. Shireen’s outstanding reputation, deep market expertise, and international experience mean she is exceptionally well placed to build an offering that responds to this demand at scale. It’s a pleasure to be welcoming her to the Pine Walk team.” Gammoh comments: “I’m hugely excited to be launching Mezura at a time when large specialty insurers and reinsurers are increasingly seeking both nimble, bespoke capital management solutions and long-term strategic partnership.” She continues: “To launch this business on the Pine Walk platform, with The Fidelis Partnership’s reputation for underwriting leadership and innovation, was a highly attractive opportunity, and I am delighted to be getting started.”
