About SaaS Insurance System "joinsure"
"joinsure" is a proprietary SaaS-based insurance core system. It offers a comprehensive suite of features, including an end-user interface for applications, a "My Page" policy management portal, and a claims processing system, alongside a robust administrative console for insurance providers. The platform is designed for versatility across various industry scenarios—whether launching a new insurance company, developing new products, or integrating insurance operations into a non-insurance company’s digital platform.
Beyond Small Amount and Short-Term Insurance, "joinsure" supports both life and non-life insurance products. By significantly reducing initial setup costs compared to traditional scratch-built development, it enables rapid product launches. This speed allows insurance providers to stay ahead in fast-evolving markets and prevents the loss of business opportunities. Furthermore, by collaborating with partner companies to embed insurance sales into their existing digital ecosystems, “joinsure” helps them deliver products that match their customers' specific needs, ultimately enhancing the overall value of their services.
