Called AppLaunchPR, it's targeting independent developers for iPhone and other smartphone platforms, including Android and BlackBerry.

Although the usual PR services like press releases and launch events are part of its offering, VSC says it will also help developers with social media and viral campaigns, focus groups and market research.

"We've seen the dramatic impact that the right marketing program can have on individual apps and it's often cited as the difference between success and failure," says VSC boss Vijay Chattha (pictured).

Existing clients for VSC in the mobile sector include advertising firms Greystripe and AdMob, as well as apps like Buzzd, Skyfire and Moderati's Virtual Zippo Lighter.

The latter went on to be downloaded more than four million times from the iPhone App Store, so VSC is clearly hoping AppLaunchPR will be able to deliver comparable results for other developers.
