Case Study: Donuts achieves 1.8× higher media effect and 1 hour/day per person workload reduction with Adjust Automate (Adjust)

Donuts - Customer Case study

Donuts, a Tokyo-based game developer founded in 2007 known for titles like Tansha no Tora, Tokyo 7th Sisters and Black Star, set out to bring advertising operations and creative production in‑house. The migration revealed shortages of internal resources, rising workload for staff, fragmented reporting across networks and difficulty optimizing creatives — so they needed a way to insource without adding headcount and while keeping ROAS-driven decision making.

By adopting Adjust Automate (Report Automation, Control Center and Rule Engine) and consolidating data into a single dashboard, Donuts automated reporting, bid/budget changes and campaign rules with only one daily approval. The result was smoother creative verification, identification of creatives that performed 5–10× better, 1.8× higher media efficiency, and roughly one hour saved per person per day (≈20 hours/month), amounting to about ¥1,000,000 saved monthly across five marketers.
