The company was established in 2009 by engineering students Nami Zarringhalam and Alan Mamedi in Stockholm, Sweden. They developed a caller ID application that garnered 10,000 downloads within a week of its release. Initially launched for Symbian and Windows Mobile platforms, Truecaller expanded to Android and iOS later that year.

As of 2021, Truecaller reported over 300 million active users, with significant growth in markets like India.
Truecaller has undergone several funding rounds to support its expansion. In 2013, it secured $19 million in a financing round led by Sequoia Capital and OpenOcean. The following year, the company raised an additional $60 million from investors including Atomico, Sequoia Capital, and Kleiner Perkins. These investments facilitated product development and market penetration. In October 2021, Truecaller went public, listing on Nasdaq Stockholm, marking a significant milestone in its financial journey.
