In an ultra-low interest rate environment, more global capital will look for investment opportunities here and this will create new tech millionaires who will use their new wealth to launch new companies or become venture capitalists themselves, said Director of the SMU Institute of Innovation and Entrepreneurship Mr Hau Koh Foo. "We can expect a 'Grab mafia' [to emerge]," he said, referring to the possibility of people associated with the company jumpstarting many start-ups in Singapore and the region. While fintech will continue to dominate Singapore's ecosystem, other up-and-coming sectors could include health-tech and ed-tech, given the country's focus on healthcare amid an ageing population, and an education system touted as world-class, said Mr Hau. He added that Indonesia's large unbanked population also makes it ripe for fintech disruption.
