Valuation: $11 billion
CEO Ben Silbermann
In May 2015, Pinterest raised a $533 million Series G funding round from investors like Andreessen Horowitz, First Mark, and Goldman Sachs, bumping the New York-based company's valuation up to $11 billion.
The virtual discovery and pinning platform has more than 175 million monthly active users, over half of whom are international. The company has expanded its focus in recent months to overseas markets like the UK, France, Germany, Japan, and Brazil, and has doubled down on increasing the advertising on its platform. Last August, Pinterest acquired online bookmarking service Instapaper.
Rumors swirled throughout 2016 that Pinterest was on the brink of going public, and in October, the company named its first chief financial officer, a signal that Pinterest could be inching closer to an IPO.
