StumbleUpon Funding Another Sign of Its Rebirth

Stumbleupon CEO Garrett Camp

StumbleUpon, which was reborn as a recommendation-and-discovery service in 2009 after an earlier ill-fated acquisition by eBay (s ebay), produced another tangible sign of that rebirth today with the news that the company has landed a Series B financing round of $17 million from a group of funds including Accel Partners, First Round Capital and Google (s goog) investor Ram Shriram’s investment firm Sherpalo Ventures. StumbleUpon CEO Garrett Camp said the company plans to use the money to expand its content-discovery platform into mobile and even onto users’ televisions.

The reference to television isn’t as odd as it sounds: when the company was founded in Calgary, Alberta in 2002 — while Camp was still in graduate school — the idea behind the service was to recreate the “channel-surfing” metaphor from television for the web. After receiving some angel funding in 2005, the team moved to Silicon Valley and launched the StumbleUpon browser toolbar, then were acquired by eBay for $75 million in 2007 — a deal that didn’t really seem to make sense to anyone at the time, despite how much eBay CEO Meg Whitman and others tried to defend it as a good fit.

The service languished inside of eBay in much the same way that Skype did, in the sense that there was little or no attempt to leverage the service or take advantage of any “synergies,” perhaps because there weren’t any. Finally, Camp and the rest of the management team bought the company back from eBay and took it private in 2009, supported by financing from Accel, August Capital and Sherpalo.

Since it escaped from eBay’s clutches, StumbleUpon has become a kind of dark horse when it comes to driving social traffic to websites — it has never really gotten as much attention as Digg or some of the other early social-recommendation systems, and yet many websites know that it consistently drives large amounts of readers to their content. A survey by search tools company Lijit last year found that the service drove almost as much traffic as Facebook, the 800-pound gorilla of social news, and a more recent one from Statcounter found that it topped Facebook in that department. Last year, the company celebrated its 10 millionth user, and as Om noted in a post recently, that’s largely because the service has focused on being simple and fun to use.

The biggest challenge for StumbleUpon now, however, is that Facebook has made it clear it intends to leverage its social-graph plugins — including the ubiquitous “like” button that has shown up on millions of websites over the past year, for which the social network recently launched new analytical tools — to become a giant recommendation engine. Given the data it has about its users and their preferences and interests based on these voting systems, it wouldn’t be difficult for Facebook to create a StumbleUpon-style service that suggests new content to users. Camp and his team may have survived eBay, but now they have an even bigger fight on their hands.
