President, IndiGo

Instead of hiring an experienced outsider, the founders of IndiGo, India's most popular airline (and its most profitable one), chose Ghosh, the company's 37-year-old lawyer, to be its president. The neophyte delivered, despite his total lack of operational experience. The low-cost carrier, which has a little over $1 billion in revenue, recently started international flights and placed the largest order in commercial aviation history for 180 Airbus A320s, totaling $15.6 billion. Ghosh's secret to success? No frills, all the way. His office is small, with no receptionist and no marketing department. On business trips he stays in budget hotels with the rest of his staff.

Job creator: IndiGo created 2,500 jobs in the past year.
