Nearly 100 insurance companies are now using Workiva’s Wdesk cloud-based productivity platform, the Ames-based company said Wednesday. “Wdesk is optimized for the insurance industry, which faces many risks and increasing regulation,” said Matt Rizai, chairman and CEO of Workiva. “Our insurance customers start using Wdesk for one or two business processes. Many now use Wdesk to improve a wide range of processes that relate to compliance and risk reporting.” Workiva made the announcement Wednesday during the annual Global Insurance Symposium being held in Des Moines. Among the insurers using Wdesk are American Equity Investment Life Holding Co. and FBL Financial Group Inc.
