Overview

About the Customer

A leading digital bank in Southeast Asia was experiencing a steep decline in app engagement, especially among dormant users. Despite UI improvements and new features, a sizable portion of its customer base remained inactive. Broad-based promotions and manual outreach were ineffective, prompting the need for a data-driven Customer Value Management (CVM) approach to re-engage and retain these users.

The Challenge

Business Challenges

Rising dormant user base and low app stickiness
Inefficient campaign targeting based on static segmentation
Lack of ML-led reactivation strategies
Limited visibility into churn drivers and behavior patterns

The Solution

Solution Approach

OBZ designed and deployed an ML-powered CVM program focused on understanding and reactivating dormant user segments. Using predictive models and dynamic journey orchestration, the team launched hyper-personalized outreach across mobile, SMS, and in-app channels. A feedback mechanism enabled real-time adjustments to improve campaign performance and longevity.

Key Solution Highlights: • ML Models for Churn Segmentation: Scored customers by inactivity level and likelihood of return • CVM Journey Orchestration: Leveraged OBZ's CVM frameworks for automated targeting across channels • Behavior-Based Campaign Design: Offers, nudges, and content tailored to past usage and user personas • Live Dashboards: Campaign tracking, A/B testing, and real-time iteration loop
