But nonetheless, a large chunk of revenues at Truecaller comes from advertisements. “While our revenues have been growing, subscription is now standing for over 20 percent of our revenues. So, subscriptions are growing, but advertising is still the largest one,” said Mamedi. In March 2017, Truecaller introduced its UPI-based payments service. The company added features including request money for its users shortly after the launch to make its service competitive. It already has more than 20 million users who are making payments through the app. But Truecaller doesn't want to take on Google Pay, Paytm, or WhatsApp Pay, Mamedi said. Payments are aimed to work complementary to its existing communication model.
