About

Independent omnichannel SSP competing with major exchange and SSP players, differentiated by supply-side curation tools and transparency offerings for both publishers and buyers

OpenX Technologies, Inc. is an independent omnichannel supply-side platform (SSP) supporting programmatic advertising across connected TV, mobile apps, mobile web, and desktop inventory. Beyond standard SSP functionality, OpenX provides supply-side curation, media quality controls, and transparency tools for both buyers and publishers. Its platform combines cloud-based infrastructure with a real-time bidding exchange and ad server data, and its products include OpenXSelect — which lets advertisers build curated inventory packages using contextual, audience, and publisher targeting — and OpenXBuild, a software suite enabling advertisers to apply custom data and decisioning logic within the OpenX bidstream before activating campaigns through a demand-side platform. In December 2021, the FTC ordered OpenX to pay a $2 million fine to settle allegations of violating federal children's privacy law, reduced from an original $7.5 million judgment due to the company's inability to pay.
