SEI Partners with Nephila Capital to Enhance Operational Efficiency in the ILS Market

Solaris Energy Infrastructure (SEI) collaborates with Nephila Capital Ltd., a notable investment manager specializing in reinsurance risk, to optimize its back- and middle-office operations across North America and the UK. Nephila, a subsidiary of Markel Group Inc., boasts over $7 billion in assets under management and has established itself as a significant player in the reinsurance industry for over two decades. The partnership aims to position Nephila strategically within the burgeoning insurance-linked securities (ILS) market, which is projected to grow from approximately $100 billion to $200 billion by 2032. By enhancing operational capabilities, SEI and Nephila seek to leverage this anticipated market expansion effectively.

Sean McDade, Nephila's Head of Operations, articulates the importance of aligning with a partner that possesses a proven track record and scalable infrastructure. He emphasizes SEI's robust technological foundation and the ability to offer customizable solutions that meet Nephila's specific needs. This partnership is particularly significant as the ILS market continues to evolve, requiring agile and efficient operational frameworks to navigate the complexities of reinsurance risk. By focusing on essential services such as reconciliation, payment processing, and data aggregation, the collaboration enhances Nephila’s operational efficiency, allowing the firm to concentrate on strategic growth initiatives.

Bryan Astheimer, Head of SEI's Investment Managers business in EMEA, echoes this sentiment, highlighting the advantages of SEI's global footprint and stability in supporting clients within the intricate ILS landscape. As of June 30, 2025, SEI manages, advises, or administers approximately $1.7 trillion in assets, solidifying its position as a leading global provider of financial technology and asset management services. The partnership not only strengthens Nephila’s operational capabilities but also reinforces SEI’s commitment to delivering tailored solutions that enhance client service and operational effectiveness in a rapidly changing market.

In addition to this strategic partnership, the collaboration signals a broader trend in the financial services industry, where firms seek to optimize operations through technology and specialized partnerships. By investing in operational enhancements, Nephila aims to maintain its competitive edge in the reinsurance sector, particularly as the ILS market continues its upward trajectory.

As the ILS market matures, such partnerships are likely to become increasingly vital, enabling firms to streamline processes and adapt to market demands. SEI’s collaboration with Nephila Capital exemplifies how strategic alliances can facilitate growth and innovation within the financial services landscape.
