Pine Walk, the specialist platform of The Fidelis Partnership, has launched Mezura Capital Partners, a new capital solutions business headquartered in Bermuda.

The new business will be led by Shireen Gammoh, the chief executive officer, who joins from Howden Re, where she served as managing director in the reinsurance broker’s Legacy and Structured Solutions team.

Mezura Capital will focus on delivering strategic capital solutions and partnerships for insurers and reinsurers, a statement by TFP said.

Its offerings will include, whole account solutions, structured casualty and specialty arrangements, and retrospective solutions, including combined prospective and retrospective covers.

Ms Gammoh brings nearly two decades of experience across Bermuda, London and the US, with deep expertise in retrospective, structured reinsurance, and capital solutions, as well as alternative/ILS capital market solutions.

Prior to Howden Re, Ms Gammoh was global head of capital advisory at Gallagher Re, and she has 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, it provides custom underwriting, operational and regulatory frameworks to support specialist and innovative underwriting offerings.

In 2025, Pine Walk grew its gross written premiums to $1 billion.

Michael Davern, UK chief underwriting officer and group head of D&F property and energy at TFP, said: “Pine Walk is a key pillar of TFP’s differentiated distribution footprint and we’re delighted to launch Mezura Capital.

“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.”

Ms Gammoh said: “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.

“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.”
