StumbleUpon is an online content discovery engine that brings users to pages matched to their personal preferences. Users are presented only with those websites suggested by their friends or other 'stumblers' with similar interests. The New York Times likened the experience to "channel surfing the Internet, or rather, a corner of the Internet that is most relevant to you." After a brief period of ownership by eBay, StumbleUpon was bought back to its original start-up status by its founders, backed by Silicon Valley investors, including Ram Shriram (of Sherpalo Ventures), Accel Partners, and August Capital.
