Truecaller Caller ID and Spam Blocking App

Truecaller was founded in 2009 by Alan Mamedi and Nami Zarringhalam, classmates at the KTH Royal Institute of Technology in Stockholm, Sweden. The service was born out of a simple need to identify incoming calls from unknown numbers, eventually evolving into one of the world's most widely used caller ID and spam-blocking platforms.

The brand is headquartered in Stockholm, where the core software development and strategic operations take place. While the technical product is 'manufactured' or developed primarily in Sweden, the company maintains a massive global presence, particularly in India, which serves as its largest market.

Truecaller is owned by Truecaller AB (formerly known as True Software Scandinavia AB), which is a publicly-traded company listed on the Nasdaq Stockholm exchange. Through its growth, it has maintained its independence and remains the central entity managing the brand globally, without being a subsidiary of a larger tech conglomerate.
