Case Study: TokyoSmartGames achieves 20% lower average CPI and saves 20 hours/month with Tenjin's Reporting Metrics API

TokyoSmartGames User Acquisition Journey

Tokyo Smart Games, a Tokyo-based mobile game publisher, struggled to scale paid user acquisition after relying on organic growth. Their small UA team spent about 20 hours per month pulling disparate data into Google Sheets and could not track ROAS for ad-revenue apps, so they needed an affordable solution to measure advertising performance and automate reporting — partnering with Tenjin (using the Reporting Metrics API).

Working with Tenjin, Tokyo Smart Games built an internal BI dashboard on top of Tenjin’s Reporting Metrics API to consolidate UA and Ad Monetization data (including retention, cohort ad revenue LTV, and ROAS) from 300+ partners. The Tenjin-powered automation saved ~20 hours per month and helped lower average CPI by 20%, freeing the team to test new channels and build custom LTV predictions.
