OpenX is a privately owned company headquartered in the United States, founded in 2007, and employs approximately 300 individuals. The company reported $138.8M in revenue as of 2024. Functioning as a programmatic advertising technology company, OpenX specializes in Real-Time Bidding (RTB) and other programmatic solutions.
OpenX published a company blog post on September 2, 2026, arguing that the "cloud tax"—a term rival executives use to describe the hidden cost of running programmatic infrastructure on public cloud servers—misdiagnoses where inefficiency sits in the advertising supply chain. The company claims to process 3 million queries per second without this cost. Earlier on August 20, 2026, OpenX confirmed that 100% of its supply meets IAB UK Gold Standard rules, announcing its support in a company blog post that ties its own certifications and supply chain tools to the trade body's expanded 2025 criteria covering connected television, retail media, and carbon emissions. This followed OpenXBuild being named a finalist on August 25, 2026, in the Best Sell-Side Focused Technology category for the AdExchanger Awards, recognized for its ability to bring custom decisioning closer to supply and help buyers and partners activate proprietary intelligence more efficiently.
