GroundTruth

GroundTruth operates an adtech business built around location intelligence, media activation and offline attribution. It provides a self-serve demand-side platform for advertisers and smaller marketers, a broader cross-channel platform for enterprise buyers, and managed services for clients that want outsourced execution. Value is created by combining proprietary visitation-based audience data with campaign delivery and measurement, allowing buyers to target likely real-world audiences and assess store-visit impact. Revenue is generated from media buying activity on the platform and from service-led campaign management and creative support.

GroundTruth is a US advertising technology company focused on location-based programmatic advertising and measurement. Its platform enables advertisers and agencies to plan, buy, and measure campaigns across display, video, audio, in-app, CTV and DOOH, with a particular emphasis on linking media exposure to offline outcomes such as store visits and conversions. Its proprietary Blueprints technology underpins audience segmentation, geofencing and visit attribution based on real-world visitation behaviour.

The company makes money from media spend flowing through its self-serve DSP and broader platform, as well as from managed campaign execution and related creative support services. Its direct customers are brands, agencies, advertisers, SMEs and performance marketers that want location-aware targeting and measurable offline attribution. As of March 2026, GroundTruth has been acquired by ZeroToOne.AI.
