About Our Project:
Safekeep is a business unit that focuses on automating insurance claim subrogation for auto, workers compensation, property and general liability claims.
Safekeep leverages data analysis and AI/Machine learning packaged into a smart workflow engine to :
Identify claims with subrogation potential
Minimize the impact of subrogation team turnover
Decrease the administrative costs of subrogation
Simplify and optimize cross-carrier interaction
UI for the smart workflow engine is built specifically for subrogation business processes, bringing together data for decision-making related to the recovery process and tracking. This includes automated processing of demand packages, settlements and payments.

Safekeep provides a digital platform for carrier-to-carrier collaboration to standardize and streamline the subrogation interaction between them.

In 2020 alone, Safekeep won the following awards:
Innovation Championship by Zurich -  Safekeep won 1st place out of 1300 solutions from around the world.
Innovation in Insurance awards -  Safekeep won the Global Silver Award out of 359 innovations from 45 countries. It was also voted one of "the 3 best innovations at a global level" in InsurTech
Plug and Play Insurance Partners voted Safekeep as the #1 InsurTech
