Who We Are

Advertising + technology. These worlds are complicated. Index Exchange was built to make things simple. We’re a global advertising marketplace where premium digital media companies sell their ad impressions transparently, in real time, to programmatic buyers.

We’re independent, with no other business interests, which is why the top companies in the advertising, marketing and tech industries choose to partner with us. Built on the pillars of neutrality, openness, and the most reliable technology, we’re the ad exchange that media companies can trust.

The Index Difference

  • No Stranger
    to Disruption

    An evolution of online media and technology pioneer, Casale Media, we were founded to address a market need for a fully transparent exchange.

  • Independent
    by Choice

    We’re privately-held which allows us to make decisions for the long-term benefit of our clients, not the immediate demands of investors, or for short term profits.

  • Growing
    Every Day

    Headquartered in New York City (Commercial Team) and Toronto (Engineering Team) with 7 regional offices, Index Exchange is comprised of more than 300 of the technology industry’s most innovative minds.

    to Technology

    We’re an engineering company at heart. While we continue to invest in our technology, our commercial team evangelizes the work of our Engineering and Product teams while providing continuous support to our clients.
