Chartboost grew music app radio Javans earnings by 45%



Over 70% of Radio Javan’s revenue comes from ads and primarily interstitial ads, so founder Hamed Hashemi is constantly on the hunt for ways to improve his in-app monetization.

Interstitial ads provide the optimal user experience for Radio Javan’s music streaming app where they place it after a user selects a music to play and before it starts playing.


The Chartboost team analyzed data to identify pockets of opportunities to improve Radio Javan’s publisher earnings. Working closely with Radio Javan, we added additional multiple line items at higher placements in their waterfall set up to capture the missing opportunity.

“Thanks to our Chartboost account manager who proactively reached out and made suggestions, we were able to increase our revenue immediately.”
