Angels 15 - Naveen Tewari

Founder of the world's largest independent mobile advertising network InMobi, Tewari is often listed among the most successful tech entrepreneurs from India. His venture started as mKhoj, a local mobile search firm, but later pivoted to a mobile advertising network with a global model, which helped him raise $200 million from Japan's Softbank last year.

Tewari, an IIT Kanpur graduate and an MBA from Harvard Business School, now uses his spare time to mentor entrepreneurs and invest in tech startups. Tewari brings to the table the experience of building a successful global company from scratch. Though his areas of interest and average amount of investment are not known, Tewari seems to be keen on internet and mobile businesses.
