Quantcast Platform

Leading independent AI-powered advertising platform with strong focus on privacy-compliant audience targeting

Quantcast is a technology company that operates an AI-driven advertising platform specializing in real-time audience measurement, targeting, and programmatic advertising. Founded in 2006, the company pioneered the use of machine learning and big data analytics to help advertisers understand and reach their target audiences across the open web. The platform processes billions of data points daily to provide insights into consumer behavior and enable precise audience targeting. Quantcast's core offerings include Quantcast Measure, a free audience analytics tool, and Quantcast Advertise, a demand-side platform (DSP) that enables programmatic advertising campaigns. The company positions itself as a privacy-forward alternative in the advertising ecosystem, particularly as the industry moves away from third-party cookies. Quantcast operates as a subsidiary after being acquired by private equity, but continues to maintain its brand identity and product offerings in the competitive AdTech landscape. The company serves advertisers, agencies, and publishers globally, processing data from over 100 million web destinations. Quantcast has been particularly influential in developing cookieless targeting solutions and consent management technologies, positioning itself as a leader in privacy-compliant advertising technology as regulatory frameworks like GDPR and CCPA reshape the industry.
