Apr 1, 2019

ZeptoLab was founded in 2010 and is based in Barcelona, Spain. To date, ZeptoLab has more than a billion downloads across their portfolio.

ZeptoLab's portfolio includes hit games such as Cut the Rope, C.A.T.S. Crash Arena Turbo Stars, King of Thieves, and more.

The challenge

ZeptoLab was shopping for a new ad mediation platform, which would increase overall ad revenue and eCPMs and provide easily accessible per-player reporting on ad performance and engagement.


- Boost eCPMs and revenue

-Discover a user-friendly mediation platform

The solution

ZeptoLab made the switch to ironSource's ad mediation platform.

ZeptoLab utilized the auto-optimization feature in ironSource’s mediation platform, which considers each network’s historical eCPM on the app and country level, to build a dynamic waterfall which is updated on a daily basis.

With this algorithm, the ironSource platform is able to place the best-performing ad networks at the top of the waterfall, ensuring that the first ad network in the waterfall is always the one delivering the most revenue.

“With the switch to ironSource’s mobile ad mediation platform, we saw an improvement not only from a technical standpoint, but also a significant increase in revenues. Equally important, ironSource’s mediation has a very user-friendly interface, making it easy to track performance and engagement.”

- Elena Solovyova, VP of Sales and Marketing at ZeptoLab

ironSource’s mediation provides developers a seamless integration with leading ad networks in the industry, including UnityAds, Vungle, Facebook Audience Network, Applovin, AdMob, and more, so they can maximize eCPMs and get the most revenue from their inventory.

The platform also centralizes reporting across all networks to provide in-depth insight into network performance - putting full inventory control back into the hands of developers.


The results

Since integrating ironSource’s mediation platform, ZeptoLab saw immediate increases in overall revenue and ARPDEU (average revenue per daily engaged user) in both Cut the Rope and King of Thieves.

Fill rate increased significantly due to the high-quality technology that ironSource provides, and global eCPM jumped from $5 to $8 with the implementation of the auto-mediated waterfall.
