To say that Vijay Shekhar Sharma is ambitious is an understatement. The founder of Paytm, India's largest digital payments company, has already revolutionized the way 400 million people spend money — whether it's buying dinner, paying an electric bill or sending money to a friend.
Over the course of his career, he's also ventured into online retail, banking and even gaming. But he's not done yet. Sharma wants to bring at least half a billion Indians into the banking system through Paytm's app. He also wants to put Paytm on the global map alongside the Googles and Facebooks of the world.
