The company right now boasts of 300 million registered users and there are more than 7 million merchants that use its platform right now. The sudden demonetisation in November 2016 catapulted the company into the public eye, as it gained recognition for its digital payments mechanism. Today, you can purchase everything ranging from milk, LPG cylinder, movie tickets to even gold through cashless transactions on Paytm.
