About

Independent AI-driven audience measurement and DSP platform competing with walled gardens and major independent AdTech players on the open web

Quantcast is a U.S.-based technology company launched in 2006 by Konrad Feldman and Paul Sutter, built around advertising, audience intelligence, and digital measurement. It serves brands, agencies, and publishers through an intelligent audience platform powered by Ara, a patented AI and machine learning engine designed to deliver automated insights and marketing performance at scale. Its tools enable direct measurement of traffic and audience characteristics across websites, video, widgets, and advertising campaigns, representing a significant advancement over traditional panel-based methodologies by coupling machine learning with large volumes of directly measured data. Used by 100 million global web destinations daily, Quantcast was also the first managed-service DSP to apply predictive models without relying on third-party data, improving performance, scale, and visibility for advertisers.
