Paytm started in 2010 as a mobile recharge website but has since diversified into e-commerce, payments, and other services. It is one of India's largest digital payment platforms with over 300 million users. Paytm raised significant funds from Alibaba and Ratan Tata to expand its business into online shopping, booking travel and bus tickets, peer-to-peer payments, and more. The company generates revenue through commissions from bill payments and recharges, fees from merchants, and charges for using coupons. While still unprofitable, Paytm aims to continue growing its business and expanding internationally.
