What Quantcast is

Quantcast is an AI-powered advertising platform for planning campaigns, reaching audiences, and measuring results across channels. Its real-time audience insights draw on more than 100 million web destinations and can be used to build segments. Advertisers can activate pre-built or custom audiences, prospect, retarget, and use contextual targeting across display, video, CTV, mobile, and audio. Reporting covers site events, conversions, and return on ad spend, with ready-to-use reports, Report Builder, and API integrations. The platform also lists spend and pipeline tracking, custom dashboards, and CRM reporting. First-party data integrations include Adobe Audience Manager, LiveRamp, Neustar, Tealium, and Zeotap. CRM email uploads are available to self-serve clients in the United States; listed onboarding integrations support first-party client data only. Quantcast offers a free plan and a 30-day trial without a credit card. There are no platform minimums, though some products have spend minimums; Campaign Budget Optimization requires a $100 USD minimum daily budget. Pricing is based on campaign costs and fees, with no fixed plan price shown. Quantcast was founded in 2006 and serves publishers, brands, and agencies.
