Two Sigma-backed program administrator Integrated Specialty Coverages (ISC) has expanded its operations with the addition of Gareth Jelley from Atrium to lead a property insurance division.

ISC has also hired Wendy Nowosiadly from Greene & Associates to oversee all underwriting for ISC and its programs.

ISC bills itself as an insurtech program administrator that builds end-to-end products utilizing artificial intelligence (AI), technology and data analytics.

Jelley spent 15 years with Atrium, according to his LinkedIn profile, most recently as president and board member of the syndicates US Operations, based in San Francisco.

He will be responsible for building out ISC’s property-based programs sold through the company’s subsidiaries, Paramount General Agency, and Safebuilt Insurance Services (SIS Insure). 

Nowosiadly focused on underwriting unsupported umbrella and excess coverage for a broad range of risks at Greene & Associates, with a focus on construction. 

She will now oversee the build out of a full-coverage primary construction product at ISC, with supported/unsupported excess products to offer coverage on a nationwide basis for construction and non-construction risks. 

Last month ISC expanded its relationship with fronting carrier AF Group to bring additional capacity including Sompo, Everest and Topsail Re to general liability programs for construction contractors on its SIS Insure subsidiary.

The fast-growing program administrator is understood to have already built a book of around $250mn of premium since its launch two years ago and is continuing to pursue M&A and team additions as it looks for further growth.
