OpenX

OpenX is a pioneering, independent programmatic advertising technology company and one of the world's leading Supply-Side Platforms (SSP) for audience, data, and identity targeting. Originally evolving from an open-source project and commercialized in 2008, the company is headquartered in Pasadena, California, and operates at the massive intersection of digital media and real-time bidding. Under the hood, their proprietary Ad Exchange and OpenAudience tools replace highly fragmented ad buying processes with a seamless, cloud-native marketplace. They process an astounding 500 billion ad requests per day, giving demand partners direct, prioritized access to over 1,200 premium publishers and 50,000+ mobile apps across multiple digital channels, including high-growth Connected TV (CTV) environments. Their primary target audience spans elite global publishers looking to dynamically maximize yield, and massive advertisers who desperately need scalable, brand-safe inventory with pinpoint demographic precision. What sets OpenX apart in the fiercely competitive and often opaque AdTech ecosystem is its obsessive focus on marketplace quality—utilizing advanced traffic quality systems to proactively block fraudulent supply—and its unique distinction as the industry's first Net-Zero verified adtech company, having fully migrated its massive serverless workloads to the Google Cloud Platform for ultimate efficiency and sustainability.
