OpenX operates an independent supply-side platform (SSP) and ad exchange within the programmatic advertising ecosystem, working with publishers and advertisers across mobile, display and connected TV. The company is headquartered in Pasadena, California, with a presence spanning North America, Europe, Asia and Australia.
Its infrastructure is 100% cloud-native on Google Cloud Platform, supporting systems that process more than 500 billion ad requests daily and serve over 1 million ad creatives. Engineering work touches several technical areas relevant to machine-learning practitioners: identity resolution and what the company terms "democratized identity" across the open web, omnichannel audience targeting interoperable with arbitrary datasets and identity types, cross-format ad serving, and real-time exchange technology operating at global scale. The platform reaches more than 200,000 brands and over 2 million direct publisher domains.
OpenX describes itself as an independent ad technology innovator. Its identity and targeting products are designed to give marketers planning and buying precision on the open web comparable to that of walled-garden platforms. The company was the first ad exchange to achieve CarbonNeutral® certification and Net-Zero verification, and states a commitment to responsible media practices alongside its work on identity.
