The San-Francisco-based startup brings an interesting twist to the ad-supported gaming experience on cell phones: not only do gamers get to play the 850 game titles that are in Greystripe’s library for free, but they are not distracted by ads as they play the games. The trick is that Greystripe inserts the ad BEFORE or AFTER he game, using the full-screen of the phone– which enables some compelling graphics, and thus higher click-thrus for advertisers. The company has deals with some 90 game publishers, supporting over 1,000 handset models. I saw a demo of their service – it was one of the rare times I was not annoyed by advertising being wrapped around my entertainment. The truck ad they showed me was a miniature version of the quality you would get on TV, which really holds your attention (even for someone not interested in trucks…). Same picture quality for the games they offer – a cool way to stay entertained for free on your commute to work… The company has already received $10 million in VC funding from Incubic Venture Fund, Monitor Ventures, and Steamboat Ventures.
