Truecaller’s Growth Under Pressure

Truecaller, the popular caller identification app, is facing significant challenges as its growth matures. With over 500 million users, the app has seen its expansion primarily driven by the Indian market, which accounts for about 70% of its user base. However, recent data shows a decline in downloads, with a 16% drop year-over-year in India and a global decline of 5% in 2025. This slowdown marks a stark contrast to the rapid growth the company enjoyed in previous years.

As competition increases from both telecom operators and smartphone manufacturers, Truecaller’s once-dominant position is being tested. Features like Calling Name Presentation (CNAP) are being integrated into telecom services, allowing users to see caller names without third-party apps. This shift is particularly critical in India, where Truecaller has built its reputation as a go-to solution for spam and unknown calls.

According to app.daily.dev, the app’s user growth has plateaued, and the increasing prevalence of built-in caller ID features on smartphones from companies like Apple and Google poses a direct threat to Truecaller’s market share. As the app faces these pressures, it has begun to explore new monetization strategies to sustain its business model.

Adapting to Market Dynamics

The competitive landscape for caller identification services is evolving rapidly. Telecom-led solutions like CNAP are gaining traction, presenting a challenge for Truecaller, which has relied heavily on its unique offerings. The introduction of CNAP allows users to identify callers based on verified records, which overlaps with Truecaller’s core functionalities. This shift in user preference towards integrated solutions could lead to further declines in Truecaller’s user acquisition.

Truecaller’s Chief Executive, Rishit Jhunjhunwala, acknowledged these challenges but emphasized the company’s commitment to maintaining its edge through innovation. The app’s recent updates include AI-driven features and enhanced spam detection capabilities, which aim to differentiate it from emerging competitors. However, these innovations must resonate with users who are increasingly drawn to built-in smartphone features.

Despite the challenges, Truecaller is not entirely without growth opportunities.

Despite the challenges, Truecaller is not entirely without growth opportunities. The company has reported a significant increase in gross in-app revenue, which rose from $600,000 in 2017 to $39.3 million in 2025. This growth indicates that while user acquisition may be slowing, existing users are increasingly willing to pay for premium features, suggesting a potential shift in focus towards monetizing the current user base rather than solely expanding it.

Advertising Revenue Pressures

A significant portion of Truecaller’s revenue comes from advertising, which now accounts for 65% to 70% of its total income. However, recent changes in the digital advertising landscape have posed new challenges. According to newsgab.com, the company experienced a loss of approximately one-third of its ad traffic from a major partner, identified as Google, which has raised concerns among investors.

Jhunjhunwala attributed this decline to an unresolved algorithm issue, which has forced Truecaller to rethink its advertising strategy. The company is now working to diversify its advertising partnerships and is developing its own ad exchange to reduce reliance on any single platform. However, the competitive nature of digital advertising means that Truecaller will have to work hard to attract advertisers who have numerous options across different platforms.

As advertising revenue faces pressure, Truecaller is also exploring other revenue streams. Its enterprise offering, Truecaller for Business, has shown promising growth, with a 39% increase in revenue in constant currency in 2025. This segment allows businesses to verify their identities and communicate with customers, providing a steady income stream as consumer-facing advertising revenue fluctuates.

Privacy and Data Management Concerns

Truecaller has faced scrutiny over its data collection practices, particularly regarding user consent and privacy. Investigations have raised questions about how the company manages its vast database of phone identities, especially in regions like India, where data protection laws are still evolving. Truecaller has denied any wrongdoing, asserting that it complies with applicable regulations.

The ongoing debate around privacy and data security is critical for Truecaller as it seeks to maintain user trust while expanding its services. As the app continues to grow, it must balance the need for data collection to enhance user experience with the imperative to protect user privacy. This balance will be crucial in retaining users who may be increasingly wary of how their data is used.

Moreover, as spam and scam calls become more sophisticated with advancements in AI, Truecaller’s ability to effectively combat these threats will be vital. The company plans to invest in technology that enhances its spam detection capabilities, which could help restore user confidence and drive growth in a challenging market.

Strategic Directions for Future Growth

Truecaller aims to adapt its business model to the changing dynamics of the telecom and app markets. The company is focused on expanding its monetization strategies across advertising, enterprise services, and premium subscriptions. With over 4 million paid subscribers, Truecaller has a solid foundation for growth in its subscription services.

As it navigates these challenges, Truecaller’s ability to innovate and respond to market demands will be crucial. The introduction of AI-based features and enhanced user experiences may help the company regain momentum. However, as competition intensifies, the path to sustained growth will require strategic agility and a keen understanding of user needs.

Truecaller’s journey reflects broader trends in the tech industry, where companies must constantly adapt to shifting market conditions and user preferences. The question remains: can Truecaller innovate quickly enough to maintain its position in an increasingly crowded market?
