Case Study: XL Catlin Group achieves US growth and modernized underwriting, claims, and billing with Guidewire InsuranceSuite

XL Catlin Group - Customer Case Study

XL Catlin Group is a global specialty property and casualty insurer and reinsurer, writing more than 30 lines of business with underwriting hubs across the UK, Bermuda, US, Asia‑Pacific, Europe, and Canada. As part of an initiative to expand its US business, the company needed to replace legacy core systems with best‑of‑breed solutions that could handle complex specialty lines, support 20 US offices, and enable entry into new markets via a phased, line‑by‑line rollout.

XL Catlin selected Guidewire InsuranceSuite — including PolicyCenter, BillingCenter, and ClaimCenter — as its new platform for rating, underwriting and policy administration, claims management, and billing. The suite’s enterprise capabilities, automation and richer source data for decision making will streamline operations and support scalable growth, helping XL Catlin pursue new markets and continue to grow profitably.
