Create and launch campaigns through integration with one of our DSP partners. Through this buying method, you get access to our high-quality supply in an open marketplace, allowing you to target specific audiences made up of individuals that meet your defined criteria, across devices and ad formats.


Private Marketplaces

With our Private Marketplaces (PMPs), we create pockets of inventory and grant you first-look access before it becomes available through the open marketplace. PMPs give you greater pricing predictability for acquiring supply, as well as greater control over placement. When building a PMP, we work with you to curate a highly customized package of mobile (in-app or web) and/or desktop supply based on your specific criteria, such as:

  • Audience segment or demographic
  • Site content or prior performance
  • Brand safety measures
  • Creative type
  • Viewability

Our PMPs are targeted through a Deal ID and can be set-up and managed by either our team, or by you through your integration with one of our DSP partners.

Always-on Segments

Our Always-on Segments allow you to access pre-packaged inventory within our DSP partner's platforms.  These segments have been developed through sophisticated targeting methods that help ensure success. Based on our work with top-tier brands and agencies, we’ve created high demand segments, as well as several that are unique to RhythmOne and help you easily capitalize on popular events or purchase triggers.
