Next Net 25 Startups to watch It's getting crowded on the Web 2.0 frontier, but there are still some startups that truly stand out. Business 2.0 Magazine identifies the ones most likely to strike gold in 2007. 1 of 25 www.stumbleupon.com StumbleUpon now has 2 million registered users drawn by its knack for finding websites that match their interests and those of others with similar tastes as they "stumble" around the Net.



Co-founder Garrett Camp (shown right), who totes around a mid-'80s Nikon F3 (yes, with actual film), came up with the idea as he was working on a master's in software engineering.



Frustrated as he tried to indulge his hobby online - "There wasn't a good way to find the best photo sites," Camp says - he tapped his own background in clustering technology. With coding help from Justin LaFrance and Geoff Smith, he created an early version of StumbleUpon. Having nailed the photo problem, the team quickly saw how the technology could click with all sorts of media.



In the same way that it matches users with like-minded websites, StumbleUpon's technology also pairs online ads with targeted demographics and interests. Now StumbleUpon is attempting to do the same for online video and video advertising. In December the startup launched StumbleVideo, a service that offers the closest thing to channelsurfing that you'll find on the Web.
