Case Study: Fiserv improves cardholder insights and dashboard performance with DataBrains

Investment research analysts, strategists, portfolio managers, compliance officers, and other market professionals can now easily and efficiently combine all forms of data from diverse sources

Fiserv, a global leader in financial services and card solutions, needed a better way to turn debit and credit cardholder data into actionable insights for its customers. The company wanted dashboards to surface KPIs like revenue, spend habits, and digital wallet usage, but its initial Tableau dashboards suffered from poor performance, long load times, and security requirements that demanded strict separation of data by financial institution.

DataBrains implemented an all-in-one solution called Card Expert, delivering role-based Tableau dashboards inside a web application along with a custom data ingestion process and secure multi-site architecture. DataBrains also optimized the original dashboards for better performance and built a custom download experience, resulting in faster, more usable insights and stronger security, though the case study does not provide specific quantitative impact metrics.
