For Will Shu, the idea behind his tech start-up grew out of frustration.
When he moved to London for the first time, to work as an analyst for Morgan Stanley, Mr. Shu could not find restaurants in the city’s financial district to deliver food when he worked late nights.
After leaving the investment bank and finishing an M.B.A. at the Wharton School, Mr. Shu returned to the British capital and co-founded Deliveroo, an on-demand food delivery service, in early 2013.
