Case Study: Flero Games achieves 500% DAU growth and blocks 40% fraudulent installs with Adjust

Increasing DAUs while preventing fraud

Flero Games is a Korea‑based mobile developer of social simulation titles (EveryTown, My Secret Bistro, Tap Tap Fish) that operates with a lean marketing budget focused on high‑value, long‑retained users. As it scaled multi‑channel user acquisition across eight apps, the team needed deeper cross‑channel reporting, raw data access for offline analysis, and protection from rising performance ad fraud to ensure marketing spend bought genuine engaged users.

In 2017 Flero integrated Adjust — using Cohort reports for KPI-driven optimization, callbacks to pipe raw user data into its BI warehouse, and Adjust’s Fraud Prevention Suite to keep data clean. FPS blocked 40% of paid installs on a major launch so those budgets could be reinvested in legitimate users, and within six months of reinvesting in older titles Flero saw DAUs rise 500% and revenue grow 250%, while gaining greater confidence and efficiency in campaign performance.
