T ake two dyed-in-the-wool Delhi boys, shift them to Chennai — where the “weather is cruel, cultural differences are stark, and the language unfamiliar” — and they will either pack their bags and head back home, or they will hunker down and turn to their work. Umesh Sachdev and Ravi Saraogi clearly belong to the latter category. Seven years after they moved to the city to be part of the IIT Madras incubator, Chennai is now “home” and headquarters of their six-year-old, Rs 9-crore business: Uniphore Software Systems, which is trying to bridge the information and digital divide in rural India through its speech-based mobile solutions. Not bad at all for two people who started their entrepreneurial journey early, but not too successfully.
