OpenX Unveils OpenXSelect, an Advanced Supply-Side Targeting and Curation Platform

OpenX Technologies, a leading global supply-side platform (SSP), announced the general availability of OpenXSelect™, a powerful new curation and supply-side targeting platform built specifically for brands and agencies. Designed to bring buyers closer to high-quality inventory, OpenXSelect delivers advanced control, targeting precision, and seamless performance optimization-all through an intuitive, buyer-first interface.

With OpenXSelect, media buyers can efficiently manage inventory quality and scale targeting using a broad array of data signals—including audience, behavioral, attention, and sustainability metrics. The platform enables real-time optimizations while enhancing working media efficiency, all within a transparent, publisher-direct ecosystem that supports the open web.

OpenX’s leadership in supply-side curation began in 2018 with the launch of OpenAudience™, the first supply-side solution powered by an identity graph, redefining audience activation directly at the supply level. OpenXSelect builds on this foundation with a robust offering shaped by continuous feedback from global brands and agencies.

“With OpenXSelect, we now have proper control over inventory quality and audience targeting. The integration with data partners is seamless, and we’ve seen marked improvement in reaching our preferred audiences. It also enables us to apply inventory standards that align closely with our brand, which has made a tangible difference to campaign delivery,” said Ash Grant, Global Head of Digital Trading at Expedia Group Media.

“OpenXSelect provides curation that is totally transparent, with levers that put the control in the buyers’ hands. Not only will we get the ability to drive outcomes against specific KPIs end-to-end and access OpenX’s proprietary identity graph, we’ll also gain the confidence of high-quality supply and the time-savings of an intuitive design,” said Wayne Blodwell, Global SVP of Programmatic at Stagwell Assembly.

“We’ve been able to cut deal setup time in half with OpenXSelect, which has opened up more time for optimization. The templated workflows make it easy to scale across channels—including CTV—and the inventory controls give us confidence in what we’re running,” said Doug Cuesta, VP, Client Strategy and Operations at Captify.

“OpenX’s identity graph has noticeably expanded our reach—more than double in some cases—compared to other platforms we’ve used. When paired with direct publisher access, and activation in our DSP of choice, it creates a more efficient media buying experience across the board,” said Neil Sweeney, Founder and CEO at Reklaim.

“This is just the beginning of what the platform—and our team—can do,” said Matt Sattel, Chief Revenue Officer at OpenX. “Our cloud-native infrastructure allows us to move fast, delivering simple, effective tools agencies need. Just as importantly, our account management teams act as an extension of our partners’ organizations, embedding with agency and center of excellence teams to do the heavy lifting and help drive results.”
