DBS Bank embarked on a second phase of digital transformation in 2015 to address threats from fintech companies and constraints on organic growth. This involved becoming "digital to the core" by overhauling its core technology infrastructure, embedding banking in customer experiences, and creating an internal startup culture among its 26,000 employees. Key initiatives included the "GANDALF" transformation program to engineer its technology like leading digital companies, making banking services invisible in customers' lives, and experimenting with new digital banking models in emerging markets like India.
