GroundTruth is an advertising platform that aims to turn online ads into real business results, especially in-store visits. The site explains how it identifies real-world audiences, reaches them across screens and channels (mobile, desktop, CTV/OTT, audio, DOOH, and direct mail), and measures outcomes like store visits, return on ad spend, and extra results. It helps brands build awareness, grow market share, and sell more products. It offers self-serve and managed services, partnerships, and a proprietary technology called Blueprints that maps the real world to digital advertising.
