After serving over 20 billion ad impressions on the AfterDownload network through our self-generated ad platform, it became clear that there isn't a SSP that is built for the needs of the inventory/content owner. Utilizing our knowledge and the platforms we built for partners, CAST was developed to not only allow large scale web properties to manage their existing inventory, but also create and manage new inventory that better aligns with user experience in a platform fully tailored to their needs. It's time to break the standard and put the power and brand back in the hands of the publisher.
