Quantcast

Quantcast provides ad-buying infrastructure to business customers. It creates value by combining media buying access across open-web inventory with proprietary audience modelling, optimisation and workflow automation. Advertisers and agencies use the platform to execute and improve campaigns, while Quantcast captures revenue from spend transacted through the platform and from related managed-service support where applicable.

Quantcast is a private US advertising technology company that operates a self-service programmatic advertising platform for advertisers and agencies. Its core product is a demand-side platform used to plan, buy, optimise and measure campaigns across the open internet, including display, video, mobile, audio and connected TV. The platform is supported by a proprietary audience graph and AI-driven optimisation capabilities designed to improve business outcomes and support cookieless targeting.

The company makes money primarily from media spend flowing through its platform, typically via take-rates, platform fees or mark-ups tied to campaign volume rather than fixed end-user subscriptions. Its customers are performance marketers, media agencies, direct-to-consumer brands and enterprise marketing teams that need open-web buying, audience intelligence and automated optimisation outside the largest walled gardens.
