Uber is locked in major tussles with local rivals in China and India, but a homegrown upstart is winning ride-hailing turf in Southeast Asia. Florian Hoppe, a partner with Bain & Company, said "it's hard for [Uber] to tailor to unique local requirements" in the region, while Singapore-based Grab understands what Southeast Asian consumers need. He pointed to Grab's service connecting commuters in Malaysia to Singapore as an example. "That's the gap" Grab has taken advantage of, he said.
