Garrett Camp and Geoff Smith are the two original founders of StumbleUpon. Those two founders got help buying back the website from other investors including Accel Partners, August Capital and Ram Shriram of Sherpalo Ventures.

When EBay purchased StumbleUpon, there were less than three million users. Currently, the most recent estimate has StumbleUpon with approximately 7.5 million users.

The StumbleUpon service is a recommendation service in which users recommend websites to other users. Depending on the number of “stumbles”, a website’s rank will be raised or lowered. Additionally, users can surf from website to website using StumbleUpon’s built-in recommendation tool.

In addition to selling StumbleUpon, EBay is reportedly considering selling Skype — a company it purchased for $2.6 billion in 2005.
