Case Study: NTT Docomo achieves 60% onboarding success rates with Amplitude

NTT Docomo Achieves 60% Onboarding Success Rates With Deep Insights

NTT Docomo, Japan’s leading mobile carrier with more than 100 million users, needed a simple but powerful way to understand customer behavior across its many services without relying on data experts. The company chose Amplitude to help its business teams uncover engagement bottlenecks, cross-service patterns, and hidden correlations in user behavior.

With Amplitude, NTT Docomo rolled out funnels, portfolio views, and audience tools to around 400 business users, enabling faster self-serve analysis and better actionability. The results included raising d-payments onboarding completion from 40% to 60% and boosting QR code payment completion by 20%, while cross-service marketing initiatives lifted conversion rates from 2% to over 16% and cut customer acquisition cost to one-eighth; overall, Amplitude helped drive an 8x improvement in marketing effectiveness.
