Vijay Shekhar Sharma founded Paytm in 2010 as an online mobile recharge website, which has since expanded to become India's largest mobile payments and commerce platform with over 150 million wallets. Paytm allows users to store money in an online wallet and make payments for services like bills, tickets, and purchases seamlessly using a virtual debit card. It received investment from Alibaba and Ratan Tata and in 2015 was granted a license to operate as India's first payment bank, expanding into banking services like savings accounts and debit cards.
