StumbleUpon

StumbleUpon is a website and content discovery service enabled by a browser toolbar. StumbleUpon uses positive and negative user ratings to form collaborative opinions on website quality. When users stumble, they will only see pages which friends and like-minded stumblers have recommended. More often than not, it’s something almost serendipitously interesting to the reader. The company expanded into video discovery in late 2006.

People who are passionate about StumbleUpon say they like it because of the surprise factor in what they see next, and the fact that the product has such a high hit rate in delivering interesting new content. The StumbleUpon site says they have nearly 7.5 million users as of April, 2009, up from 1.7 million in December 2006. Over 15 million personalized recommendations (“stumbles”) are delivered daily.

StumbleUpon was acquired by Ebay in May 2007, and operated as an independent subsidiary for 2 years. In April 2009, StumbleUpon was bought back from Ebay by Garrett Camp, Geoff Smith, Ram Shriram, Accel Partners and August Capital.
