Quantcast, founded in 2006, is an advertising technology company that operates an AI-powered Demand Side Platform (DSP). The platform enables marketers to target audiences across the open internet and measure campaign outcomes. Central to its offering is the Audience Graph, a proprietary system that processes billions of decisions per second to identify high-conversion audiences and generate insights.
The company's technical work spans artificial intelligence, machine learning, large-scale data processing, and audience measurement. Its product suite includes the Quantcast DSP for programmatic advertising, the Audience Graph for audience identification, and Quantcast Measure, a free analytics tool adopted by 100 million web destinations daily for audience measurement. The company operates with a privacy-by-design approach.
Quantcast's scale is underscored by the volume of real-time data it processes: the Audience Graph handles billions of decisions every second, while Quantcast Measure provides audience insights across a vast network of websites. The firm sits at the intersection of digital marketing and digital advertising, applying machine learning to connect brands with relevant audiences at scale.
