Jenius was set up as a startup within an existing bank to address the major opportunity of serving Indonesia's growing consuming class with a digital financial service. Jenius offers a mobile and web app with an international debit card and physical touchpoints. It has strong market performance with over 0.8 million customers. Building Jenius as a startup taught the bank how to implement agile methodology, microservices architecture, and open APIs. Jenius also provided valuable lessons and capabilities to enable a broader digital transformation.
