AI-Driven Customer Segmentation for a Leading Retail Bank
Client Overview
A top-tier retail bank serving over 10 million customers across diverse regions, offering services ranging from personal banking to wealth management. The bank struggled with one-size-fits-all campaigns and underwhelming customer engagement.
Business Challenge
Despite a broad customer base, the bank faced:
- Low engagement from digital marketing campaigns
- High churn rates among digitally savvy and high-net-worth segments
- Lack of visibility into customer behavioral differences and evolving financial needs
- Limited personalization across mobile app, website, and outbound communications
This made cross-selling, upselling, and customer retention difficult in an increasingly competitive financial services space.
