The company sources specialty risk capacity indirectly through reinsurance to support its Members' premium base. In 2021, it launched Mission Underwriters to provide start-up financing, underwriting capacity, and operational support to entrepreneurial underwriters. In 2022, it established Flywheel Re, a reinsurance sidecar designed to facilitate institutional investor participation in the Risk Exchange portfolio by providing multi-year underwriting capacity. Flywheel Re's reinsurance treaty has been extended and increased through additional capital from new and existing institutional investors, with the most recent upsizing occurring in March 2026. In 2023, the Risk Exchange was modified to allow third-party insurance companies to join and access the platform directly. Risk Exchange Insurers contributed 30% of the total Exchange Written Premium for the year ended December 31, 2025, and are expected to represent the majority over time. The company offers quota share reinsurance contracts to Risk Exchange Insurers or assists them in establishing reinsurance relationships with other Risk Capital Partners, with the objective of these insurers writing an increasing percentage of Exchange Written Premium and reducing capital requirements over time.
