Case Study: OuiCar saves 10% of media budget and increases installs with Adjust's Fraud Prevention

OuiCar saves 10% of media budget thanks to Adjust

OuiCar, founded in 2007, is France’s leading peer-to-peer car rental app with over 35,000 cars and more than two million users. As competition intensified, the team focused on data-driven user acquisition but found installs rising without corresponding revenue due to widespread ad fraud skewing their results.

By implementing Adjust’s Fraud Prevention solution, OuiCar quickly identified and turned off fraudulent campaigns, reallocating budgets to high-performing channels. The move saved 10% of media spend, allowed a 6% increase in genuine installs from reinvestment, rejected over 12% of paid installs (80% of which were click spamming), improved active user growth, and enabled real-time CPI adjustments.
