Quantcast is an advertising technology company headquartered in San Francisco, California, founded in 2005 by Konrad Feldman. The company operates an AI-driven platform for programmatic advertising, audience measurement, and data analytics, serving advertisers and publishers across channels including CTV, audio, video, display, mobile, and native. Quantcast's core product, the Quantcast Intelligence Cloud, uses machine learning to analyze audience behavior and optimize ad targeting, with a particular emphasis on cookieless solutions as the industry moves away from third-party cookies.
As of mid-2026, the company reports annual revenue of approximately $173.3 million, according to ZoomInfo, and employs between 500 and 1,000 people across 13 locations. Quantcast competes in the digital advertising sector against firms like SimilarWeb and Comscore, focusing on audience intelligence and measurement. The company has not disclosed recent funding rounds or an exit event; it remains privately held.
In recent years, Quantcast has emphasized its AI Suite and Audience Graph capabilities, positioning itself as a provider of cookieless targeting and omnichannel campaign management. The company serves a range of industries including agencies, DTC retail, ticketing, tourism, travel, gaming, finance, B2B, and B2C. Quantcast was recognized as a Leader in G2's Fall 2025 Report for its advertising platform.
The broader ad tech market faces headwinds from privacy regulation and shifting identity solutions, and Quantcast's reliance on its proprietary data and AI models is central to its competitive positioning. The company's financial trajectory shows moderate revenue relative to larger competitors, and its private status limits public visibility into profitability or growth rates.
