Case Study: Bank Danamon achieves fivefold increase in customer take-up and faster reporting with Talend

Striving to understand and respond to each customer needs

PT Bank Danamon, Indonesia’s sixth-largest bank with about four million customers, faced intense competition in a market of 115 banks and struggled with fragmented data across ten siloed marts and slow ETL processes. That fragmentation made it hard to deliver timely, personalized experiences, slowed reporting (reports took half a day), and hindered efforts to increase digital engagement and customer “stickiness.”

Danamon implemented an on‑premises Hadoop-based big data platform using Talend (with partners Artha Solutions and iZeno) to ingest 40+ source systems, enforce data governance, and enable real‑time customer profiling and fraud detection. The new solution cut report production time by half (now under two hours), increased take-up of targeted offers fivefold, sped fraud investigations, improved IFRS9 compliance, and is consolidating the bank’s data into a governed single source of truth for future use cases.
