Private Marketplaces

Data-rich impressions. Exclusive brands & publishers. High-quality, brand-safe content. Just a few of the reasons to consider buying or selling inventory in a private marketplace.


Open Packages

Align your brand with high-quality content & premium publishers. Easily find and target premium and hard-to-find supply by taking advantage of one of our open inventory packages or let us custom curate one based on your unique requirements.

Brand Safety

From brand-safe inventory to ad verification & powerful configuration tools, we are laser-focused on protecting your brand. Contextual & privacy data lets buyers make smart purchase decisions while rigorous ad quality & fraud detection tools provide publishers full control.
