About Nephila
Nephila was co-founded by Frank Majors and Greg Hagood in 1997 to invest in insurance-linked securities focused on natural catastrophe. In 2003, the co-founders purchased the company from Willis to establish an independent company, Nephila Capital Ltd. In November 2018, MKL, a global specialty insurer and investment company, acquired 100% ownership of the Firm.

Since its founding, Nephila has broadened its investment strategy, expanding beyond natural catastrophe. In 2005, the Firm launched its Climate Risk strategy, the first and only dedicated climate risk manager focused on providing insurance solutions to support a sustainable economy, such as renewable energy and agriculture.
