Pinterest raises $100m

PICTURE THIS: While Mark Zuckerberg and his nerd posse were occupying Wall Street yesterday (see next item), upstart Pinterest was raising $100 million in a financing round that values the start-up at $1.5 billion, sources told the WSJ. The funding is led by Japanese e-commerce site Rakuten. Pinterest was last valued at $200 million in a funding round late last year. The online scrapbooking website has become the latest Silicon Valley darling because of its explosive user growth. Last month, Pinterest passed the 20-million user threshold, after hitting its first million just last July. So what’s so compelling about looking at a bunch of photos, anyway? (5/18a)
