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 sites, we’ve been relentless in raising the bar for programmatic excellence.
Today, we’re bringing the same efficiency and scale we established in traditional web media decades ago to newer formats and channels like streaming TV, mobile, native, and more.
As we continue on our mission to accelerate the evolution of ad technology, our focus remains on setting the standard for the industry—from inventory quality to leading levels of transparency and the continued pursuit of a level playing field for all to transact in.
