KUALA LUMPUR Four years ago, at a coffee shop just outside Kuala Lumpur, a young woman with a smartphone in her hand, looking a bit out of place, eagerly explained to local taxi drivers how to use a ride-hailing app.
This is how Tan Hooi Ling started her business. The 32-year-old is the co-founder and chief operating officer of Grab, the biggest ride-hailing mobile service provider in Southeast Asia, whose app has been downloaded more than 21 million times in six countries.
