The funding numbers behind Pinterest are eye-boggling: it raised $100m in October 2012, $200m in February 2013, then another $225m in October. And now it has announced another $200m round. In total, Pinterest has now raised $764m in funding since its launch, with the latest round valuing the company at $5bn. This, despite the fact that it has only just started selling ads, with the prospect of meaningful revenues. “Pinterest has a vision of solving discovery and helping everyone find things they’ll love. This new investment gives us additional resources to realise our vision,” said CEO Ben Silbermann in a short statement after the news broke yesterday about the new round. Nestle, Kraft, Gap and Expedia are among the brands paying for the first wave of 3-6-month ‘promoted pin’ campaigns on Pinterest (Bulletin, 13-May-14).
