Tony Fernandes
Tony Fernandes's businesses have a simple mission -- to serve the underserved. Since 2001, the Malaysian entrepreneur's budget airline AirAsia has flown more than 100 million passengers -- many of whom couldn't afford the continent's legacy carriers -- to destinations from Paris to Phnom Penh. Fernandes is using AirAsia's web traffic to jump-start a fleet of follow-ups: Tune Hotels ("Five-star beds at one-star prices"), Tune Talk (cell phones), Tune Money (insurance, prepaid Visa cards), and Tune Tone (movies and music).
