Ezanga
eZanga was founded on May 29, 2003, by husband and wife team Rich and Beth Kahn. It originally operated in the affiliate advertising space, but eZanga changed its focus to fighting bot traffic and combating ad fraud with the launch of the completed Traffic Advisors in 2005. eZanga continued to develop its product offerings with the January 2012 launch of AdPad, a proprietary ad management system for advertisers. Both AdPad and Traffic Advisors have continually gone through new iterations as the advertising industry continues to evolve.
