GroundTruth

GroundTruth is a location-intelligence performance advertising platform (formerly xAd) that helps brands and agencies plan, launch, and measure omnichannel ad campaigns tied to real-world behavior. Its Ads Manager, proprietary Blueprints location-mapping technology, and Dynamic Intent Prediction AI turn visitation, behavioral, and demographic signals into targeting and store-visit and sales attribution across verticals including QSR/restaurants, CPG, auto, retail, healthcare, education, travel, and political. GroundTruth is backed by Emergence Capital and IVP and became part of ZeroToOne.AI in 2026. This profile was enriched by the API Evangelist pipeline; GroundTruth exposes a self-serve advertiser platform (ads.groundtruth.com) but publishes no public developer API surface.

GroundTruth is profiled on the APIs.io network. Tagged areas include Company, Martech, Advertising, Location Intelligence, and Marketing.

GroundTruth’s developer surface includes signup flow, engineering blog, support, getting-started guide, and 6 more developer resources.
