Case Study: NTT DOCOMO scales AI-powered customer experiences with Amplitude

NTT Docomo reduces campaign analysis time by 90% with Amplitude

NTT DOCOMO, Japan's largest mobile carrier, faced the challenge of extracting actionable insights from its vast and complex customer data across multiple services. With over 100 million customers, the company needed to move beyond slow, specialized analytics that created bottlenecks between data and action. To address this, they partnered with Amplitude to establish a foundational layer of self-serve behavioral analytics.

Amplitude provided a solution that began by creating a shared behavioral language across the organization, democratizing analytics for over 1,000 users. The vendor then introduced Amplitude AI Agents to compress workflows, automating data synthesis and investigation. This resulted in a 90% reduction in campaign analysis time for one branch, improved conversion rates from 2% to 16%, and a significant reduction in cost per acquisition, enabling faster and more trusted decision-making at scale.
