About a year ago Quora began introducing advertising as a way of making money.
The round values the company at roughly $1.8 billion, according to a company spokesperson (who said that the valuation had roughly doubled from its previous valuation of $900 million).
Quora launched privately in 2009 but and quickly drew buzz in the tech community in part because it was started by two well-respected early Facebook employees. The website opened to the public in 2010, serving as something of a high-end message board where people can ask questions and get solid answers.
The site currently serves 190 million unique visitors a month, according to a blog post from Sam Altman, president of YCombinator.
YCombinator’s YContinuity venture fund led the round along with Collaborative Fund.
