How does Insillion utilize existing Rater-Excels to create insurance products?

Insillion uses insurers’ existing Rater-Excel to simplify product creation. The platform uses Excel  files as the source for rating logic and rate tables. Inputs and outputs are named within the file, allowing mapping through Insillion. This setup lets business users manage rating and rule configurations without any coding.

Insillion converts Excel-based rating models into ready-to-use APIs without coding, allowing insurers to launch products in days. Traditional implementations often involve lengthy build cycles, handoffs between business and IT, and constant back-and-forth for changes. With Insillion, underwriters retain ownership of the rating logic in Excel, while IT teams integrate via the generated APIs. These APIs, along with ready-to-use portals, cut long implementation cycles and enable faster distribution.

Insillion’s Excel-to-API converter maintains a single source of truth by converting the business and premium computation logic from Rater-Excels into centralized, versioned APIs. Once uploaded and integrated, all frontend and backend systems access rating results through the same API. This eliminates the need to recreate logic across multiple systems and ensures consistent rating outcomes.

Underwriters are comfortable developing premium logic in Excel and the transfer of knowledge to other teams can often be a challenge, since there are frequent changes from different stakeholders. The time and efforts spent in developing and re-developing the products can cause a ROI burn when the cost of launching the product is greater than the ROI gained from launching the product itself. Hence, Insillion helps carriers and MGAs overcome development costs by utilizing existing Rater-Excels to launch products.
