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. Truecaller Trust & Confidence Indices – A proprietary measurement framework that quantifies three critical dimensions of brand impact: Attention, Trust & Confidence to Act.
2. Brand Lift Studies– In partnership with Kantar and VTION, these studies measure full-funnel brand outcomes such as awareness, recall, favorability, and purchase intent on Truecaller. Early trials with category-leading brands have indicated positive movement across attention, trust, and Truecaller’s proprietary Trust and Confidence Uplift metric.
3. 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.
4. Multivariate Testing – Powered by RainMan Consulting, This framework runs controlled tests to isolate the impact of different variables, helping advertisers identify the most effective combinations for achieving the best-performing campaign outcomes with precision.
5. Marketing Mix Modeling (MMM) – Powered by RainMan Consulting, this framework leverages elasticity models and “what-if” simulations to estimate Truecaller’s incremental contribution to marketing ROI, enabling brands to optimize media investment allocation across channels.
