Meet Your Team: Programmatic Supply

In a competitive adtech market, adjoe stands for greater transparency and fairness for app publishers and advertisers – and a more relevant and enjoyable experience for users.

It’s exactly for this reason that adjoe’s Programmatic team has built its own mediation platform WAVE. It’s not only driven by a backend application that decides which ad to show but also by our Android and iOS SDKs. These render the ads for the user and provide useful tracking events to the backend.

The WAVE SDK serves millions of in-app ads a day in different formats, and our backend system handles a few billion auctions in real-time every day to help game developers monetize their apps.
