Case Study: Lotum achieves 25% time savings and greater control over ad mediation with Google AdMob

Lotum gains greater control while spending 25% less time with Google AdMob platform and mediation

Lotum, a 35‑person German developer of 16 mobile quiz and word games including 4 Pics 1 Word, was spending too much time and resources manually managing mediation waterfalls across its apps. To simplify operations and stay nimble, Lotum turned to Google AdMob’s platform and mediation tools to replace their heavy in‑house mediation system.

After A/B testing AdMob mediation (including its bidding solution, Ad Inspector and integrations with Firebase), Lotum fully migrated its apps to Google AdMob. The switch reduced mediation management complexity and saved the team 25% of their time while maintaining revenue and ARPDAU, replaced an in‑house QA tool, and freed staff to focus on user experience and growth.
