We founded YAP in 2013, after noticing an opportunity for publishers and advertisers to optimise their monetisation strategies and reporting.

Since then, we’ve expanded to offer comprehensive analytics and data services to help publishers increase revenue.

Our Story


YAP is a comprehensive connector framework for publishers, linking multiple channels into a single data cube.

We manage the flow of advertising revenue between publishers and advertisers, by providing the best opportunities for advertisers and the maximum return for publishers. 

YAP is proudly powered by IBM’s leading reporting and analytics software.
