Our story
Index Exchange was born out of a need for an advertising marketplace that was fair and balanced. We saw the opportunity to create an exchange that empowered media owners to thrive in the digital age, while delivering unparalleled efficiency, transparency, and value across the entire programmatic ecosystem.
From the very beginning, we’ve worked to build exceptional standards that deliver on our vision of total market efficiency. By pioneering header bidding, advancing industry protocols, creating opportunities for addressable campaigns, and eliminating made-for-advertising supply, we’ve been relentless in raising the bar for programmatic excellence.
Today, that same focus is driving the next evolution of our exchange. With Index Cloud, partners can run their technology directly within our infrastructure—bringing intelligence closer to the impression and enabling a new model for more efficient and performant sell-side decisioning.
As we continue to accelerate the evolution of ad technology across every channel, our focus remains on setting the standard for the industry—from inventory quality to transparency to a level playing field where all participants can compete and grow with confidence.
