Vijay Shekhar Sharma, 41, founded closely-held One97 Communications and its brand Paytm (rhymes with ATM) almost two decades ago. It offered a variety of digital services before moving into payments in 2014, just as millions of urban Indians began shopping online.
Two years later, India’s banks created the Unified Payments Interface, a tech umbrella to help banks and fintech startups create services quickly, and the government eliminated high-value currency notes, turbocharging demand for Paytm’s services. Sharma, a self-described hippie who loves to sprinkle U2 and Pink Floyd lyrics into his conversation, now has backers including Alibaba’s Jack Ma, SoftBank’s Masayoshi Son, and Berkshire Hathaway’s Warren Buffett.
