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 developed a marketplace specifically for children's and teens' data, where it vets publishers for high-quality content and regulatory compliance, routing this traffic through a separate channel. This initiative addresses the online ad industry's past reliance on "plausible deniability" regarding children's privacy and the "actual knowledge" concept under the Children’s Online Privacy Protection Act (COPPA), which previously allowed operators to treat traffic as general audience unless provably aware of collecting data from children under 13. Earlier, on July 8, OpenX partnered with Horizon’s Product Foundry and Programmatic teams to evaluate whether enhanced identity signals could improve open-web addressability and bidding precision, testing privacy-safe solutions like ID5 against standard identifiers. Previously, on June 30, OpenX began a search for a new chief executive officer following the departure of Matt Sattel, who had taken on the role in February 2026, amid similar high-profile exits among competitive supply-side platforms.
OpenX offers 3 products in the ad tech and services industry. OpenX's product portfolio comprises of data, targeting and identity and RTB and programmatic.
