ROI of Trust: Bridging the Measurement Gap
Truecaller's measurement framework evaluates what truly drives outcomes - whether brand messages capture attention, inspire trust, and translate belief into confidence to act. Built on the Truecaller Trust and Confidence Framework, the suite introduces a new way to make trust measurable..

The Middle East and Africa (MEA) region remains a high-growth market for Truecaller, driven by its expanding digital ecosystem and mobile-first users. With rising adoption of Truecaller and growing demand for our solutions, MEA offers strong potential for both brand engagement and trusted communication. We remain committed to deepening our presence and partnerships across the region in the times ahead.

Hemant Arora, Vice President, Global Head Ads Business at Truecaller, said "With high daily engagement,, Truecaller has grown into a platform where user attention is both meaningful and actionable. We're committed to helping advertisers tap into this attention more effectively by offering verified, privacy-safe tools to measure impact in a smarter and more collaborative way".

"Every impression on Truecaller carries a halo of trust," said Archana Roche, Global Head of Measurement at Truecaller. "Through our Trust Uplift and Confidence Framework, we can now quantify how ads in this trusted environment build credibility and inspire belief. When people see brands within this halo, they instinctively perceive them as more reliable and worth engaging with".

Five Pillars of the Truecaller Measurement Suite
The Truecaller Measurement Suite-designed and validated through in-house experimentation and independent research partnerships - comprises five integrated solutions:

1. Brand Lift Studies -Developed by Truecaller's Measurement team in partnership with Kantar, VTION, and other leading research firms, these studies measure full-funnel brand outcomes such as awareness, recall, favorability, and purchase intent. Early trials with category-leading brands have indicated positive movement across attention, trust, and Truecaller's proprietary Confidence Uplift metric.

2. Incremental Reach Analysis - Through partnerships with VTION and privacy-safe data clean rooms, Truecaller maps unduplicated audiences beyond major social platforms, achieving 28-35% incremental reach on average.

3. Multivariate Testing - Enables simultaneous multi-cell experimentation across creatives, placements, formats, and audience segments - all powered by Rain Man Consulting. The framework runs controlled parallel tests to isolate the incremental impact of each variable, helping advertisers uncover optimal configurations for attention, recall, and engagement across audience cohorts with statistical precision.

4. Marketing Mix Modeling (MMM) - Powered by Rain Man Consulting it integrates platform data with advertiser inputs to quantify Truecaller's contribution to overall marketing ROI. The framework leverages elasticity models and " what-if " simulations to estimate Truecaller's incremental contribution to marketing ROI, enabling brands to optimize spend distribution across channels.

5. Truecaller Trust & Confidence Indices - A proprietary measurement framework that quantifies three critical dimensions of brand impact

• Attention: Contextual engagement and verified ad recall in trusted environments.

• Trust: Brand credibility transfer enabled by spam-free, authenticated communication.

• Confidence: Trust-in-action measuring the consumer's likelihood to interact, transact, or purchase after ad exposure in a trusted and scam protection platform.

Privacy-Safe, Partner-Certified Measurement
All measurement solutions operate within privacy-safe environments, utilizing independent validation and passive behavioral observation rather than declared user data. The Measurement team works closely with independent research partners to ensure methodological rigor, transparency, and advertiser confidence.
