Truecaller’s Growth Conundrum: Navigating India’s Telecom Landscape
With over 500 million users worldwide, Truecaller has become an indispensable tool for identifying unwanted calls and messages. However, the company is now facing a critical juncture as growth slows in its largest market, India, and competition intensifies across telecom networks and smartphone platforms. Truecaller’s success has been largely driven by India, where it boasts over 350 million users, accounting for approximately 70% of its global base. The country’s sheer volume of spam and unwanted calls has transformed Truecaller from a simple caller ID service into a more embedded layer of everyday communication.
As the Indian telecom market continues to evolve, Truecaller is introducing features such as AI Assistant and Family Protection to drive monetization, alongside tools like Community Suggestions to stay relevant in the face of increasing competition. This comes as telecom-led solutions like Calling Name Presentation (CNAP) and dedicated number series for verified business calls gain traction in India, while smartphone makers like Apple and Google build caller identification and spam-blocking capabilities into their operating systems.
Truecaller’s growth dynamics are being closely watched by investors, who have seen the company’s shares plummet by about 78% since its 2021 IPO. The company’s CEO, Rishit Jhunjhunwala, has acknowledged recent headwinds in parts of the business, without elaborating further. As Truecaller navigates this challenging phase, it is essential to examine the operational mechanics and market realities driving its growth trajectory.
Behind the Scenes: Truecaller’s Operational Mechanics
One of the key questions from investors has been around the impact of CNAP in India, which displays caller names based on KYC records at the network level without requiring third-party apps. Truecaller’s Jhunjhunwala views CNAP as validation of the problem, rather than a disruption, highlighting the company’s global platform and richer intelligence layer spanning spam detection, fraud prevention, business identity, and user context across calls and messages.
However, analysts like Bharath Nagaraj, director of equity research at Cantor Fitzgerald, point to pressure in the company’s advertising segment, driven in part by changes from Google, as a more immediate challenge. Truecaller lost roughly one-third of ad traffic from its largest partner, Google, in August 2025, due to an unresolved “algorithm issue.” The company is now adding new partners and building its own ad exchange to reduce dependence on any single platform.
Truecaller’s shift in growth dynamics is also reflected in its revenue streams. While downloads have plateaued in recent years, gross in-app revenue has risen sharply, from $600,000 in 2017 to $39.3 million in 2025. The company’s presence on iOS has grown, and it has stepped up efforts on Apple’s platform, including launching real-time caller ID for iPhone in early 2025. Nonetheless, Apple recently expanded its call-screening capabilities, which could reduce the need for third-party apps among iPhone users.
Who Wins, Who Loses, and Who Gets Disrupted?
Truecaller’s growth trajectory has significant implications for various stakeholders in the Indian telecom market. The company’s enterprise offering, Truecaller for Business, which enables companies to verify their identities and communicate with customers via calls and messaging, has been growing steadily, with revenue rising 39% in constant currency in 2025. This segment is likely to benefit from Truecaller’s expansion of its chat services to partners and the offering of tools such as verified business caller ID.
However, the company’s consumer subscription business, which has over 4 million paid subscribers globally, may face challenges from Apple’s expanded call-screening capabilities. Truecaller’s Jhunjhunwala has acknowledged the need to adapt to the changing landscape, emphasizing the company’s focus on addressing the rising complexity of communication, as spam and scam calls become more sophisticated with advances in AI.
Ultimately, Truecaller’s ability to sustain growth across markets will depend on its ability to navigate the evolving Indian telecom landscape and adapt to the shifting needs of its users. As the company expands across all three revenue streams – advertising, enterprise services, and premium subscriptions – it must balance utility, scale, and user privacy, addressing concerns around data collection and consent.
The Skeptical Case: What Could Go Wrong?
While Truecaller has made significant strides in expanding its offerings and revenue streams, there are concerns around the company’s dependence on advertising revenue. The loss of ad traffic from Google in August 2025 highlights the risks associated with relying on a single platform. Furthermore, the highly competitive advertising landscape, with brands able to spend across multiple digital platforms, may continue to pressure Truecaller’s ad revenue.
Additionally, the company’s expansion into new markets and revenue streams may not be enough to offset the challenges posed by CNAP and Apple’s call-screening capabilities. As Truecaller navigates this complex landscape, it must be prepared to adapt quickly to changing market realities and user needs.
Next Steps: What to Watch
As Truecaller continues to evolve, there are several key milestones to watch. The company’s next earnings call will provide insight into its progress in addressing the challenges posed by CNAP and Apple’s call-screening capabilities. Furthermore, the expansion of its chat services to partners and the offering of tools such as verified business caller ID will be critical in driving growth in its enterprise segment.
Ultimately, Truecaller’s ability to sustain growth across markets will depend on its ability to navigate the evolving Indian telecom landscape and adapt to the shifting needs of its users. As the company continues to expand its offerings and revenue streams, it must balance utility, scale, and user privacy, addressing concerns around data collection and consent.
