The caller identity app Truecaller said that it crossed the 450 million user mark earlier this week. The company said that it added 50 million users in the past 10 months and 15.5 million users since the beginning of 2025. India is the companys biggest user base. So it wasnt surprising when Truecaller promoted Chief Product Officer and MD of India operations, Rishit Jhunjhunwala, to the CEO position after the companys co-founders decided to step back from day-to-day operations last year.Image Credits: TruecallerJhunjhunwala said that while India remains a critical market for Truecaller, it also saw growth in other regions.We are proud that we now serve more than 450 million users globally. As before, we continue to see steady growth in our largest market, India, but the fastest relative growth is in markets outside of India. So far in 2025, we see strong growth trends in Latin America, South Africa, Kenya, Nigeria, Malaysia, and the US, to mention a few markets, he mentioned in a blog post.Truecallers growth and position in India might be challenged as the countrys telecom department is pushing mobile carriers to implement its own caller ID system, which could rival the Sweden-based companys product.The company said that throughout Q4 2024, it maintained an active user base of nearly 430 million users. The company had positive results for the quarter ending December, with net sales up 23% and profit after tax up 29% year-over-year. The companys stock is up more than 33% year-to-date at the time of writing.Earlier this year, the company also integrated its caller ID product to work better with iOS. Until then because of operating system level restrictions from Apple, the live caller ID feature wasnt on par with its Android equivalent. Truecaller has also focused on creating value beyond just caller ID by introducing products like call recording and transcription and an AI-powered assistant for call screening. It has been trying to improve its experience as an SMS and chat client.
