Zadspace Unveils Ad Product

Los Angeles-based Zadspace, an advertising firm backed by DFJ Frontier, Crosscut Ventures and Gideon Hixon Fund, has unveiled its advertising product, saying Tuesday that it has exited beta testing of its service. Zadspace adds full color, 4x6 advertisements on cardboard shipping boxes. The firm--which until recently had been in stealth mode--is also backed by marketer Lester Wunderman. Zadspace said it has delivered more than 500,000 of its ads for 25 different advertisers over its beta, and claims a 50% higher response rate than direct mail.
