How Singapore’s Largest Bank Achieved Double-Digit MAU Growth With Perx
Singapore’s biggest bank activated millions of customers using micro-experiences powered by the Perx Lifestyle Marketing Platform, driving a 25% lift in MAU and 221,000 additional customer actions in a single year.
With over 4 million customers, the bank needed a scalable way to deepen in-app engagement beyond essential transactions. Traditional campaigns weren’t creating frequent, meaningful interactions, and the bank wanted to influence specific behaviours at scale, without manual effort or long IT cycles.
Perx embedded a library of personalised, gamified micro-experiences directly into the bank’s mobile app. Across the year, the bank launched more than 300 targeted, mobile-first experiences, each designed to drive pre-defined customer actions, increase frequency of usage, and create new touchpoints between the bank and its customers.
Using Perx, the bank delivered 331 personalised micro-experiences, drove a 25% increase in MAU, and generated 221,000 additional customer actions in 2022. These experiences created 15 million customer-brand touchpoints across the year, significantly increasing engagement beyond regular banking transactions and reinforcing the bank’s position as a digital engagement leader in Singapore.
