“There was a time people challenged me and said I’ll fail to raise funds. They said I don’t have any MBA in my team. How’ll my brand survive? When Flipkart took over the market people said I’ll not be able to raise funds. ‘Woh baat mene dil pe le li’ and the result is Jack Ma, Warren Buffet and Masayoshi Son, the superstars as investors”, said CEO and founder of Paytm, Vijay S Sharma. His motto is 'go big or go home'.
