Our History

Stephen Catlin established the Catlin Underwriting Agencies syndicate at Lloyd’s in 1984. From there, it grew into a global insurer that regularly outperformed the market and wrote US$6bn in annual premium when it was acquired in 2015.  

In 2019, Catlin and Paul Brand co-founded Convex with $1.7bn of initial committed capital to underwrite insurance and reinsurance for complex specialty risks. The company received an A.M. Best rating of A- (Excellent) and regulatory approval to operate in London and Bermuda.

Many of the people that made Catlin successful now work at Convex, so there is a continuity in management style and underwriting ethos. We have also welcomed leaders in their fields from across the insurance industry, bringing a diversity of thought and approach.
