Case Study: Global Online Game Developer achieves 65% improvement in ROAS with Treasure Data

How a first-party data strategy supported by Treasure Data delivers a 65% improvement in ROAS

A leading global online game developer wanted to boost advertising efficiency for new title launches and build more direct relationships with players, but its valuable first‑party data was trapped in more than a dozen siloed systems. That fragmentation prevented deep behavioral insights and the ability to deliver “always‑on” personalized customer journeys at scale.

By partnering with Treasure Data and Leverage Lab, the company unified customer profiles (including IP matching), captured high‑purchase‑intent signals, and applied sophisticated segmentation, orchestration, and attribution. The effort drove a 65% improvement in ROAS, 12% average subscription growth, and doubled the data available for behavior insights—enabling continuous personalization, better targeting, and more effective upsell/cross‑sell.
