Tappx aims to help developers and app owners promote their apps and find new users in a cost effective way. This was the rationale behind creating a cross promotion platform to help developers grow without incurring in advertising costs. The developers in the community earn credits when they show other developers ads on their apps. These credits can be used in turn to buy ad placements on other apps, applying filters per country and app category. One of the key assets of the startup is its technology that helps optimize the ads placed to maximize the number of downloads and increase efficiency. This solution is really innovative and allows developers to find new users with no additional costs.
