Case Study: Testbook achieves ₹40L+ in revenue and personalized user engagement with WebEngage

Testbook Unlocks ¹40L+ in Revenue by Leveraging In-App Surveys for Personalized User Engagement and Product Insights

Testbook, a leading online platform for government exam preparation in India, needed better, real-time signals from highly engaged app users to understand motivations, validate product ideas, and nurture intent—especially since broadcast channels like email and WhatsApp were often ignored. The core challenge was collecting contextual, actionable feedback to improve segmentation, product strategy, and revenue outcomes across high‑value cohorts such as UPSC aspirants.

By deploying WebEngage in‑app surveys at high‑intent moments and building targeted nurture journeys (notably a 5‑day UPSC onboarding), Testbook captured clear user intent and plugged insights into product, marketing, and CRM. The approach drove over ₹40L+ in revenue, validated SuperCoaching purchase drivers, uncovered a sizable “combo” aspirant segment for bundling opportunities, and powered 10+ campaigns that improved engagement, retention, and conversion.
