Greystripe is the world's first in-game mobile advertising network.
Greystripe's AdWRAP advertising network is a system that sources ads from advertisers and delivers them through their network of mobile games. By enabling this value chain, Greystripe allows publishers to make advertising revenue from their mobile games and to distribute them for free. Consumers win because they get great ad-supported mobile content for free.

Monitor Ventures invested in the series A and B rounds along with Incubic Ventures, Steamboat Ventures and WS Investments. Greystripe was acquired by ValueClick in April 2011.
