What We Do
Mezura is an MGA based in Bermuda, partnering with global and specialty insurers and reinsurers seeking portfolio-level capital solutions across whole-account and multi-line structures. Our offering spans whole-account solutions, structured casualty and specialty arrangements, and retrospective transactions – including combined prospective and retrospective covers. Mezura combines prospective, retrospective and integrated capabilities to solve complex capital and liability challenges. Mezura is a Pine Walk Group company, founded in April 2026.
Type
Mezura has a broad focus across (re)insurance classes, focused on diversified portfolios. Our solutions are tailored for portfolio-level transactions with strong alignment of interests and long-term partnership.
Platform
A differentiated approach to capital and liability solutions.
Traditional reinsurers focus on standardized, product-based solutions, while typically specialise in run-off transactions. Mezura brings together prospective and retrospective capabilities in a single platform, enabling clients to address complex capital, reserve and growth objectives through integrated, tailored solutions.
Key Differentiators
- Integrated Capital: Solutions: Combining prospective and retrospective capabilities cover within a single coordinated solution.
- Scalable Capacity: Supporting transactions across a broad range of sizes, complexities, and client requirements.
- Strong Strategic Partnerships: Backed by leading legacy specialists and global asset managers to support large and complex reserve transactions.
- Tailored Structures: Every solution is designed around the client’s unique objectives rather than predefined products.
