About GroundTruth GroundTruth is a media platform that drives in-store visits and other real business results. Using observed real-world consumer behavior, including location and purchase data, we create targeted advertising campaigns across all screens for advertisers. We then measure how consumers respond to the campaigns, including if they physically show up to a store location or website, to understand the real business results generated by a brand’s advertising.
