AdSounder is the audio ad exchange. We make ad agencies money by providing access to a wide audience on a variety of apps using market segmenting to increase the value of each ad placement.In addition, we provide a revenue stream for publishers, freeing them to focus on technology and content acquisition. The problem is mainstream music apps have shifted to free, ad-funded business models but the increase in user numbers resulted in an excess of ad space. Meanwhile, niche music apps lack the reach attractive to advertisers and as a result they are generally unprofitable.AdSounder solves both problems by collating their ad space onto one easy to access platform, confirming advertising campaigns with clients and distributing to each app based on its ability to service the desired audience within the required timeframe at a pre-negotiated price per spot. AdSounder is a key link in the value chain providing advertisers with impactful audio campaigns for mobile.
