REUTERS/Eric Thayer/Files Investors in Pinterest Inc. are doubling down on the image-bookmarking site with a new round of funding at a rich valuation. Pinterest is in talks to raise $500 million in a round of funding expected to value the five-year-old company at around $11 billion, according to people familiar with the matter. It is unclear whether any new investors will join the round, which is expected to close in the coming weeks. With the latest round, investors peg Pinterest’s value at more than twice the $5 billion price tag it was assigned when it last raised funds last May. The hefty valuation is a reflection of Pinterest’s potential as it remakes itself from a scrapbooking site into a destination to discover new things. A Pinterest spokesman declined to comment. The fresh infusion of funds will help Pinterest keep pace with its growth spurt. Last fall, the company signed a new lease for more office space near its San Francisco headquarters to accommodate its growing head count, which totals more than 500 employees. The company is seeking to capitalize on its user growth, deepen its footprint in Europe and Asia and develop a business model. Pinterest’s unique U.S. visitors reached an all-time high of 75.8 million in January, up 37% from the same time a year earlier, according to comScore. Pinterest doesn’t disclose user numbers. Pinterest, whose users post and share images, or “pins,” to pages or “boards” on a variety of topics, is also moving forward with its moneymaking efforts at a faster clip. The company opened up its advertising offerings in January and recently started testing new types of ads on the service. According to Pinterest, early results show that users interact with these new ads—called promoted pins—just as much, if not more, than user-posted pins, a sign that users find the advertisements relevant to their overall experience. The startup is entering a crowded field of social advertising that pits it against more mature competitors like Facebook Inc., Instagram and Twitter Inc. as well as buzzy up-and-comers like messaging service Snapchat Inc. Pinterest executives have said, however, the company is uniquely positioned because a user’s pinning behavior reveals what they intend to do in the future, whether it is to buy a handbag, take a tropical vacation or try out a new home improvement project. Those intents give clear signals to advertisers looking for their target consumer. Before the new funding, Pinterest had raised a total of $764 million in funding from investors including venture-capital firms Bessemer Venture Partners and Andreessen Horowitz, hedge fund Valiant Capital Partners and Japanese e-commerce firm Rakuten Inc.
