Age:
Lin: 35; Khan: 37
Co-CEOs, NQ Mobile
Smartphone, $200. Protective case, $30. All that personal data on your mobile device? Priceless. It's little wonder that Lin, a professor who founded his mobile security business with $15,000 and a few grad students in 2005, is doing well. The Chinese company now makes the majority of its revenue overseas, and it's growing quickly -- revenues of $20 million jumped 125% last quarter, and they've risen more than 10-fold since 2008.
Khan, who worked for mobile giants like Motorola and Samsung in the past, signed on as Lin's co-CEO earlier this year. His mission? To raise NQ's profile and international reach beyond its current 204 million users in 150 countries. He expects the growing popularity of mobile payments and electronic health records will help. —Erika Fry
