“With OpenXBuild, we can apply our audience enrichment and bidding algorithms directly inside the exchange. By evaluating impressions closer to supply and bidding more selectively, advertisers have seen a 70% reduction in cost-per-conversion on OpenX traffic compared to unshaped SSP inventory.”

The OpenXBuild Software Suite

Real-Time Bidstream API

Safely and easily deploy your data and decisioning in a secure container within OpenX cloud infrastructure. Shape bid requests pre-auction for real-time audience targeting and smarter bidding, maximizing efficiency and improving performance.

Identity Resolution API

Enrich your data assets to increase qualified omnichannel reach. Match audience data across leading identity frameworks using the industry’s largest independent, interoperable supply-side ID graph, reaching 272 million plus people.

Auction Insights API

Power measurement and insights. Access privacy-forward log-level data — including people exposures, supply dynamics, and auction results — to power reporting, model training, and campaign optimizations.

What Is Containerization?

Containerization makes it easier for advertisers to bring their proprietary intelligence closer to supply by securely deploying custom models, data logic, or decisioning code in a private, cloud-native environment. With OpenXBuild, advertisers can use containerized custom decisioning to enrich and shape bid requests before they reach the DSP — minimizing latency, maximizing media efficiency, and prioritizing the opportunities most likely to drive performance.
