How Truecaller found its true calling in India

How the spam-screening, caller-id app found a wildly successful market in India

When Swedish nationals Nami Zarringhalam and Alan Mamedi founded Truecaller in 2009, they didn’t have India on their radar, not even remotely. They had built the caller-id app for personal use, to screen calls from angry companies who wanted reviews on their workplaces taken down from a website founded by Zarringhalam and Mamedi. That site was called Jobbigt, meaning troublesome, it was later sold for $20,000, and the money was used to buy equipment to test Truecaller.
