What valuation did Pinterest reach in its October 2011 funding round?

Pinterest reached a valuation of US$200 million in its October 2011 funding round.

The round was Pinterest’s Series B financing and brought in US$27 million, led by venture-capital firm Andreessen Horowitz. Earlier investors, including FirstMark Capital and Bessemer Venture Partners, also participated. The financing gave Pinterest a much higher valuation than its previous early-stage funding and signaled growing confidence in its visual-discovery model.

At the time, Pinterest was still a young service built around saving images and links to themed collections called boards. Its growth accelerated after the launch of an iPhone app in early 2011, followed by an iPad app and a mobile version for other users. The company’s traction helped attract larger venture investors.

The figure is a valuation, not the amount raised. The round raised US$27 million, while US$200 million described the company’s estimated value after the investment. It is also distinct from Pinterest’s later billion-dollar valuations, including the US$1.5 billion figure associated with Rakuten’s 2012 investment.
