Case Study: Gamejam achieves 32% ROI increase with Tenjin Reporting Metrics API

Gamejam ROI +32% using Reporting Metrics API

Gamejam, a Vietnam-based team of 10+ developers with over 200 million installs and rapid growth in hyper-casual titles, faced a bidding-scale challenge: advertising 30+ games across 10+ ad channels in 25 countries created thousands of daily bid decisions that required automation to capture high-LTV users. To address attribution and LTV needs they were already using Tenjin’s attribution dashboard and moved to Tenjin’s Reporting Metrics API to enable more granular, data-driven bidding.

Using Tenjin, Gamejam integrated the Reporting Metrics API into its internal BI system to pull cohort ROI by bid dimension and built triggered rules to adjust bids automatically (e.g., increase bid 10% if day‑1 ROI > 50%). With Tenjin’s data driving in-house automated bidding, Gamejam increased ROI by 32% on ad channels that support bidding and reported quarterly profitability gains attributable to the Tenjin-enabled automation.
