Truecaller, the widely used caller identification platform, is navigating a challenging period marked by slowing user acquisition and increased market competition. Downloads in India, its largest market, fell 16% in 2025, according to data shared with TechCrunch by Sensor Tower, prompting investor concerns. The company's shares have dropped 78% since its 2021 initial public offering, reflecting skepticism about its future growth trajectory.
Truecaller's journey, much like a patient's health, shows signs of stress in its core metrics. Here is what the data actually says: downloads from India, the company's most significant market, decreased by 16% year-over-year in 2025. Globally, new user acquisitions declined 5%.
This marks a reversal after several years of consistent expansion, according to Sensor Tower data provided to TechCrunch. Before you panic, read the methodology; these figures track new installations, not active users. Separate analysis from Appfigures shows downloads peaked at 175 million in 2021 before stabilizing around 120 million annually in subsequent years.
These numbers tell a clear story. India has long been the heart of Truecaller's user base, accounting for over 350 million of its 500 million global users. The app transformed from a basic caller ID service into an essential communication layer for many, largely driven by the high volume of spam and unsolicited calls in the region.
This deep integration, however, now faces significant external pressures. Truecaller's share of new downloads from India has gradually shifted from over 70% at its peak to the mid-50s in recent years, indicating a move towards other markets for new user growth. One major competitive factor is the emergence of telecom-led solutions.
India’s telecom regulator, in collaboration with network operators, is implementing Calling Name Presentation (CNAP). This system displays caller names based on Know Your Customer (KYC) records directly at the network level. This means users could see caller identification without needing a third-party application.
Truecaller CEO Rishit Jhunjhunwala, however, views this development differently. “Truecaller operates as a global platform with a much richer and dynamic intelligence layer,” Jhunjhunwala told TechCrunch, asserting that the company's capabilities extend far beyond basic caller identification, encompassing spam detection, fraud prevention, and business identity verification across various communication channels. He sees CNAP as a validation of the problem Truecaller addresses, not a disruption to its broader offerings. Smartphone manufacturers are also integrating advanced call screening features.
Companies like Apple and Google continue to build caller identification and spam-blocking capabilities directly into their operating systems. Apple, for instance, recently expanded its call-screening functions, potentially lessening the need for external applications among iPhone users. This trend creates a challenging environment for standalone apps.
In response to these competitive pressures and slowing growth, Truecaller has introduced several new features. These include an AI Assistant, designed to screen calls and manage communication, and Family Protection tools, aimed at expanding its utility beyond individual users. Community Suggestions also help the platform stay relevant by incorporating user feedback.
The company has also intensified its focus on the iOS platform. Appfigures data shows Truecaller's presence on iOS grew from under 5% of its total downloads in 2020-2021 to approximately 11-12% recently, reflecting a strategic pivot towards markets often associated with higher user value. Real-time caller ID for iPhone launched in early 2025.
Feature updates now aim for parity with the Android app. Meanwhile, the company's advertising segment, a critical revenue source, has experienced notable headwinds. Bharath Nagaraj, director of equity research at Cantor Fitzgerald, pointed to pressure in advertising as a more immediate challenge for Truecaller. “If you look at the earnings for the company, 65%–70% of it now comes from ad revenue,” Nagaraj stated to TechCrunch.
This concentration makes the company particularly vulnerable to changes in the digital advertising ecosystem. Truecaller's last earnings call revealed a significant disruption in this area. The company reported losing roughly one-third of its ad traffic from its largest partner in August 2025.
While Truecaller did not name the partner, analysts on the call identified it as Google. Chief Financial Officer Odd Bolin confirmed the partner still accounts for more than a third of total revenue. Jhunjhunwala attributed this sharp drop to an unresolved “algorithm issue.” The company is now actively working to mitigate this dependence by adding new advertising partners and developing its own in-house ad exchange.
This is a crucial step for diversification. However, even an in-house ad exchange may not entirely resolve the underlying challenge. The digital advertising market remains intensely competitive.
Brands have numerous platforms where they can allocate their spending. “You can show your ads on Truecaller, but you can also show them on Facebook,” Nagaraj explained. This highlights the ongoing struggle for ad dollars against established tech giants. The landscape is crowded.
Despite the plateauing downloads and advertising challenges, other aspects of Truecaller’s financial health show resilience. The headline is dramatic, but the data is not uniformly negative. Appfigures data indicates that gross in-app revenue has risen sharply.
From a modest $600,000 in 2017, it surged to $39.3 million in 2025. By April 20, 2026, it had already reached $13.4 million for the year. Monthly revenue from in-app purchases now consistently exceeds $2 million and continues to climb.
This demonstrates a clear shift towards monetization through direct user payments. Another core component of Truecaller's monetization strategy is its enterprise offering, Truecaller for Business. This service allows companies to verify their identities and engage with customers through calls and messages.
The segment has shown consistent growth, with revenue increasing by 39% in constant currency during 2025. Jhunjhunwala outlined plans to expand this platform globally, opening chat services to partners and offering verified business caller ID tools to help enterprises authenticate their identity and reach their customer base effectively. This is a strategic pivot.
Alongside its enterprise push, Truecaller has also expanded its consumer subscription business. This segment now boasts over 4 million paid subscribers worldwide. These users opt for premium features such as advanced spam protection, AI-based call screening, and an ad-free experience.
This growing subscriber base offers a more stable and predictable revenue stream compared to advertising. Historically, Truecaller has faced scrutiny regarding its data collection practices. An investigation by The Caravan raised questions about user consent and how its vast database of phone identities is built and maintained, particularly in India where data protection laws have been less stringent.
Truecaller has consistently denied any wrongdoing, stating it complies with all applicable regulations. This debate underscores the broader tension between providing a useful service at scale and upholding user privacy. It's a delicate balance.
Why It Matters: This evolving landscape for Truecaller reflects fundamental shifts in how digital communication platforms operate and monetize. For hundreds of millions of users, especially in markets like India, Truecaller has been a critical tool for navigating unwanted calls. As caller identification capabilities move from standalone apps into network infrastructure and smartphone operating systems, the competition for user attention and data intensifies.
This transformation impacts not only Truecaller's business model but also raises broader questions about digital privacy, data governance, and the future of third-party utility applications on our devices. The outcome will shape how we interact with our phones daily. Key Takeaways: - Truecaller's growth is slowing, with India downloads down 16% in 2025, according to Sensor Tower. - The company faces increasing competition from telecom network-level solutions and smartphone manufacturers. - Despite advertising revenue pressures, Truecaller’s in-app purchases and enterprise offerings show strong growth. - Truecaller is diversifying its revenue streams through premium subscriptions and business services to reduce reliance on advertising.
Truecaller sees significant opportunities ahead, despite these challenges. The company plans to address the increasing sophistication of spam and scam calls, particularly those driven by advances in artificial intelligence. It aims to expand across its three primary revenue streams: advertising, enterprise services, and premium subscriptions.
Investors will closely watch how effectively Truecaller can adapt its core value proposition as caller identification becomes increasingly integrated into network infrastructure and device operating systems. The next few quarters will provide a clearer picture of its strategic execution and market resilience.
