I am not exaggerating when I say I have never met a more professional and efficient group of people. I just sat next to the CEO of AdTech on the plane and told him there was no way we’d leave ZEDO. Your reporting, ease of use, ranking, and geo-targeting are industry leading and I’ve used them all, DART, Atlas, etc. Reporting is especially well done, this is a true asset to ZEDO as much as your human capital.
