Case Study: German Bank achieves 50% match rate and enriches 60M profiles with Zeotap

German Bank Increases Retention Rate by 12% Through Unified Customer Identity

a german bank faced challenges in customer acquisition due to a competitive landscape with new fintech players. The bank needed to target the right potential customers more effectively to avoid overspending and improve its Return on Advertising Spend. To address this, it partnered with Zeotap.

Zeotap used its Customer Data Platform (CDP), which includes natively built-in Third-Party Data Enrichment, to unify the bank's customer data and build a single customer view. This data was then used to build lookalike audiences for acquisition campaigns. The solution yielded a 50% match rate, with 60 million profiles enriched. This provided better input for the bank's models, directly impacting ROI and revenue growth, and helped reduce yearly customer attrition by 20% to 30%.
