Wang Xing, co-founder of Meituan Dianping, aspires to "make life better for everyone", says the prospectus for the world's largest food delivery company, which floated recently in Hong Kong at a value of US$53 billion (S$73 billion). That is an impossible dream, but his company is changing how millions eat.

Uber's on-demand taxi service used to be the ultimate disrupter, but rides for people are being challenged by delivery of food. Motorcycles and bikes speed around cities, carrying meals for millennials without the time or inclination to cook for themselves. Uber hopes to grab more of an expanding market in Europe and Asia by partnering with Deliveroo, one of its delivery rivals.
