Seven independent ad tech companies debuted a programmatic consortium on Thursday that pools their supply- and demand-side cookie IDs into one shared identity asset.
The consortium is helmed by AppNexus, MediaMath and LiveRamp, which provides the data matching. Other launch partners include Index Exchange, Rocket Fuel, LiveIntent and OpenX.
And it’s a shot across the bow of Facebook and Google, which suck in a majority of digital ad dollars.
