Paytm is India's largest mobile payments and commerce platform founded in 2010. It initially offered mobile recharging and bill payment services but has since expanded into travel, ticketing, shopping, and peer-to-peer payments. After demonetization in India in 2016, Paytm saw a huge surge in users and transactions as it promoted cashless payments. It now has over 500 million users and competes with other digital wallets in India.
