PixPulse jets ahead

We first ran into serial entrepreneur David Xue when he was with Lockdown Networks. He's now the head of PixPulse, a company developing a mobile media application that enables users to share photos and videos directly from mobile devices. There are obviously a fair share of companies targeting this type of opportunity, but membership at PixPulse has now topped 10,000 -- not bad for a startup that just launched last October.
