Madbox achieves "mad growth" monetizing with ironSource interstitials
Jun 17, 2019

Madbox is a game developer based in Paris, France.

Their portfolio includes Stickman Hook, Dash Valley, Marble Race and Sausage Flip.

The challenge

Being a game developer with hyper-casual titles, short and skippable interstitial video ads are a crucial part of Madbox’s monetization strategy. Their primary objective is being able to maximize revenue while still providing a positive experience for their players.

The interstitial video ads Madbox was serving, however, were not delivering the revenue results they were aiming for. Madbox was looking for a monetization partner that could serve high-performing interstitials which would boost their overall revenue.


- Boost interstitial performance

- Generate increased revenue

The solution

Madbox integrated the ironSource SDK, after recognizing the company as one of the market leaders in gaming monetization. With the SDK in place, Madbox activated ironSource interstitial ads, in addition to ironSource rewarded videos and banners, and began serving them to all their users.

“The ironSource product - both user acquisition and monetization - are extremely powerful and are constantly improving. Together we’re achieving Mad growth.”
