Or take the 26-year-old who co-founded a software start-up in Bangalore, and helped turn it into a global technology services giant. And then, 28 years later, Nandan Nilekani quit Infosys, to drive something he believed in: giving a digital identity to a billion Indians.
That little start-up, and others like it, pushed India's information technology and business process outsourcing (IT-BPO) industry across the $100bn mark in 2012.
