Truecaller just crossed a milestone most apps never reach. The challenge now is proving that scale can still translate into growth.
In March, the company said it had passed 500 million monthly active users and added 50 million users over the previous year.
That is a major milestone, but it arrives as the business faces a more difficult stretch in India, where user growth is slowing, competition is shifting closer to the telecom layer, and newer revenue lines are being asked to do more of the work.
Why India matters more now
India is still the center of Truecaller’s business. According to TechCrunch, the company has more than 350 million users there, roughly 70% of its global base. That same report said downloads in India fell 16% year over year in 2025, while global downloads fell 5%.
That does not mean the app is suddenly losing relevance. It means Truecaller’s biggest market is no longer delivering the same easy expansion it once did, even as it continues to drive much of the company’s reach, engagement, and commercial value.
Indian telecom operators are rolling out Calling Name Presentation, or CNAP, a network-level caller ID system that displays a caller’s KYC-registered name without requiring a third-party app. That overlaps with one of the core reasons many people first installed Truecaller, even if it does not replace spam labeling, caller reputation, or fraud signals built from user reports and broader app intelligence. CEO Rishit Jhunjhunwala told investors CNAP had been partially rolled out and could affect user growth as deployment expands.
That is why the company is leaning harder into product layers that go beyond basic identification. Scam protection is becoming a more active feature set, not just a passive caller lookup tool, as seen in Truecaller’s Family Protection rollout and broader changes in mobile fraud defense, such as Google’s expansion of AI scam protection on Android devices.
Why the AI pivot has to work
The more immediate business risk is revenue concentration. Truecaller disclosed on its Q4 2025 earnings call that it had lost roughly one-third of its ad traffic from its largest partner in August 2025, and analysts on the call identified that partner as Google. The same report said that the partner still accounted for more than one-third of total revenue.
That makes the company’s newer bets more important. Truecaller had surpassed 150 million users outside India, giving it more room to diversify geographically. But that alone will not solve the problem. The business now needs subscriptions, enterprise products, and AI-assisted safety features to carry more weight, especially if advertising remains vulnerable and India continues to mature.
Truecaller does have assets to work with: a large installed base, strong brand recognition, and a product tied to a problem that is not going away. Spam, fraud, and scam attempts remain a daily reality for mobile users, and the broader risk environment continues to expand, as shown by reports of malicious browser extensions posing as TikTok downloaders.
The open question is whether Truecaller can turn that relevance into a sturdier business model. If subscriptions and AI-driven safety tools grow quickly enough, the company can look more resilient than its recent numbers suggest. If they do not, the 500 million-user milestone may be remembered less as the start of a new chapter than as the high point of the old one.
