Understanding eCPM, fill rate, and ARPDAU is essential for any mobile game developer who takes monetization seriously. These metrics tell you exactly how well your ad mediation setup is performing and where the opportunities for improvement lie. But having the data is only useful if you have a platform that can act on it – and that is what sets cas.ai apart in the mobile ad mediation space. The platform provides impression-level revenue data as a standard feature, tracking every ad impression back to the specific user, device, and traffic source. This allows developers and UA managers to calculate real ROAS, analyze cohort performance, and make informed decisions about campaign optimization. The mediation system itself connects apps to multiple mobile ad networks using both waterfall optimization and in-app header bidding, ensuring maximum eCPM across rewarded video ads, interstitial ads, and banner ads. With over one billion monthly impressions and 5,000 apps on the platform, cas.ai delivers consistently strong fill rates and competitive revenue per impression. The company also functions as a mobile game publisher with a Top-50 global ranking. More than 200 games, 36 million monthly active players, and weekly UA spend exceeding one million dollars demonstrate the scale of the publishing operation. User acquisition, app store optimization, creative production, and campaign management are all handled in-house. The dashboard centralizes everything – ad revenue metrics, UA performance, cohort analysis, and A/B test results – in a single interface. Fast payouts from day five, **** options, and co-investment opportunities for long-term partners round out the offering. The 150-person team across four European offices provides real developer-focused support. For studios seeking a mobile monetization platform that combines deep analytics with effective ad mediation and optional publishing, cas.ai is one of the strongest choices available today.
