Our mission

At Truecaller, we are on a mission to build trust in communication. We were founded to create a service that would easily identify incoming calls from unknown phone numbers, but as the problem with fraud and unwanted communication grew, so did we.

In order to provide the best service possible it’s vital for us to understand the challenges and problems people using Truecaller experience daily when communicating in a digital world. We want to hear your insights, they are very important to us as we continue to build our products for you.

Our method

Communication is about conversations. Both through calls and messages. We can look at how people use the Truecaller app, when you use it. But without a real conversation, we can’t understand what reality you live in.

We want to be as direct as possible and reach out by calls or through an instant message.
