Naveen Tewari, 

Mobile advertising network InMobi serves billions of ads every day. At 759 million active users per month, it’s only behind Google’s AdMob and Facebook. By focussing on emerging markets, InMobi has differentiated itself from those two, which are strong in developed markets. In 2012, it entered China, where it’s the leader. In North America, it’s behind Google, Facebook, and Millennial Media. InMobi built a range of capabilities from software development kits to ad monetisation to app analytics. Tewari is proud that his 900-strong company operates mostly from India.
