Case Study: Large Financial Institution improves customer retention with Saggezza’s GraphQL middleware

Decreasing Page Load Times Improves Customer Retention

Large Financial Institution was struggling with slow page load times in its application, creating frustration for customers and raising concerns about the cost and ROI of a full middleware rewrite. Saggezza stepped in to address the issue while the client planned a front-end redesign, using a modern stack that included React, Apollo, and GraphQL.

Saggezza implemented a GraphQL middleware layer that preserved the existing RESTful endpoints, reduced duplicate API calls, and improved data handling through Apollo-based state management. As a result, the application moved to a single GraphQL request model, page performance improved, and customer retention during onboarding increased, with speed identified as the key driver of the improvement.
