About
One of the largest independent programmatic advertising exchanges globally, competing directly with Google Ad Manager, Magnite, and PubMatic in the SSP space
Index Exchange is an independent supply-side platform that helps media owners connect with leading brands, operating as a neutral, conflict-free exchange to advance efficiency, transparency, and quality across the programmatic ecosystem. Publishers can use the platform to monetize digital ads across every channel and ad format, managing their entire portfolio from a single interface while maintaining full control over transactions and customizable inventory deals. The platform drives inventory value by increasing competition among top global buyers and agencies, and also offers identity solutions and analytics tools to improve user experience and build trust with both advertisers and site visitors. Recent partnerships have expanded its capabilities to include attention data, brand lift measurement, audience targeting, pause ad inventory, and mobile gaming inventory with first-party data, supporting cross-channel activation across mobile, streaming, and beyond. With more than 20 years of industry leadership, the company continues to evolve ad technology by applying intelligence closer to the impression and reducing waste across the supply chain.
