Case Study: Teltech boosts RoboKiller customer retention and revenue with Leanplum

How Leanplum Helps RoboKiller Retain Customers

Teltech’s RoboKiller is a top‑grossing iOS app that uses AI to block spam calls, but the team lacked end‑to‑end visibility into the customer journey. They needed better behavioral analytics, reliable A/B testing and CRM integration to understand which features drove engagement, why users churned, and how to optimize trials and monetization.

Leanplum gave RoboKiller a multichannel engagement and testing platform—variable experiments without app updates, CRM integration, and product analytics—enabling targeted push/email reactivation campaigns, paywall and trial optimization, and feature‑usage insights. The result was measurable retention and LTV gains, increased revenue from winbacks of canceled-but‑installed users, and a stronger foundation for personalized messaging as data integration expands.
