In related news, Coherent has formed a partnership with Unqork, a New York-based startup that offers a system for creating insurance applications without the direct use of software language coding. Insurers that combine the Unqork system with the Spark system can feed insurance models into the Spark system using Microsoft Excel spreadsheets, according to Coherent.
Spark can then move the model information into rating, product recommendation, illustration and underwriting systems, the company says.
