Read how GSPANN helped a US-based Fortune 500 departmental store chain with over $20B annual sales and more than 1000 stores in building a cost-effective in-house loyalty platform. We combined multiple existing loyalty programs based on the TIBCO loyalty platform into a single comprehensive microservices-based reward system. It has a new reward mechanism and additional features that significantly improve the redemption rate. Key highlights: The new loyalty reward system supports 65+ million customers. 10 million users have already been migrated to the new loyalty platform with performance exceeding all benchmarks. The client plans to migrate the remaining 55 million users by Dec 2021. The solution can handle up to 150% of the peak-load transactions handled by the previous loyalty system. The scalable system helps the client in serving their customers better. We used Jenkins to achieve 100% test automation. The solution supports batch automation, uploads files into GCP buckets, turns on/off specific features, and publishes reports in an easy-to-understand format. This case study can help you understand how the success of a digital loyalty program depends significantly on the technology platform it is built on. Using a legacy software can prove to be a roadblock in scaling the loyalty program with the growing user base and augmenting it with new features in accordance to the changing market dynamics. Overcoming such challenges is necessary to improve user engagement and redemption rates.
