Started in 2009 by Alan Mamedi and Nami Zarringhalam, the Swedish company provides with an application that helps a user search for contact information (based on name, number or address), identify incoming calls, block calls one does not want to receive, and make personal contact suggestions based on time and place.
    
The free mobile application shows name of the person calling to a user even if the number is not saved in the phone.
    
"India is a very unique market and when one startsgrowing in India, one can grow really fast. We have an office in Gurgaon. We will be adding more people in India next year for our marketing team", said Mamedi.
    
"Right now we have one person in India. We are also planning R&D centres probably in Bangalore or Pune," Mamedi said.
    
Truecaller, he says, is installed in around 40 percent of smartphones in India. The country has over an estimated 115 million smartphone subscribers, behind only China and the US.
    
The app in most of the phones is pre-installed including Micromax in India.
    
Mamedi and Zarringhalam were struck with the idea of this application when they found that there wasn't any single app to trace calls.
    
"We thought we need to solve this problem ourselves. We wanted to make people-search readily available to anyone. That was how Truecaller was born," said Mamedi.
    
"For the people here in India, blocked and spam calls are a big issue. And Truecaller helps in identifying callers and even blocking unwanted ones," he said.
    
The company currently has 60 employees from nearly 40 nationalities in its head office here.
    
"Of them four are Indians. Seventy percent of the staff are programmers, two of them are women from India," he said.
    
Recently Truecaller set up office in Beijing. Next year, it plans to start offices in Dubai, Sao Paulo and in Kenya.
    
Truecaller also runs another app, Truedialer, which offers users details of a person before the outgoing call is connected.
