Based in Stamford, Connecticut, General Star is one of the leading specialty and surplus lines providers in the U.S., and the Contract P&C Division offers insurance products on a non-admitted basis by General Star Indemnity Company, a wholly-owned subsidiary of General Reinsurance Corporation, a member of the Berkshire Hathaway family of companies.

General Star selected ClarionDoor’s Insured Rating to automate a time-consuming and traditionally manual quoting process, and to obtain greater control managing the underlying rates and business rules. Going forward, ClarionDoor will develop a general liability and commercial property rating solution to be utilized by General Star’s appointed managing general underwriters (MGUs) and internal underwriters. The solution also includes an ACORD XML web service for both lines of business.

“The rapid pace of change in the U.S. delegated underwriting authority marketplace called for a streamlined, single-entry solution that could be accessed by our appointed MGU clients and internal underwriters,” said Matt Brown, division manager for General Star, of the decision to partner with ClarionDoor. “ClarionDoor was selected based on its track record in developing leading edge cloud-based rating solutions for the excess and surplus market and for its speed-to-market development process.”

Insured Rating is a modern rating engine platform that supports ISO and non-ISO rates, developed from the ground up to operate, perform, and scale exclusively in the cloud. The technology suite provides all the tools and services necessary for rating any line of business or transaction type, and utilizes industry standards, such as ACORD XML. Insured Rating provides integration with several third-party services, including Google Maps, MapRisk and CAT modeling.

“General Star is a leading specialty and surplus lines provider and we are delighted to be selected as its rating partner,” said Patrick M. McCall, Chief Sales Officer at ClarionDoor. “It is dedicated to investing in technology designed to improve the ease-of-use for clients and internal underwriters. We look forward to working with General Star to deliver a superior rating solution and customer experience.”
