Coworking space startup WeWork today disclosed a $433.9 million funding round in a new document on file with the U.S. Securities and Exchange Commission.

That’s higher than the $400 million figure the Wall Street Journal reported last month. Hat tip to Dan Primack at Fortune for tweeting a link to the filing, which does not name specific investors.

WeWork representatives did not immediately respond to a request for comment.

The valuation of WeWork appears to have gone up quickly. In December, when it was reported that WeWork had raised a $355 million funding round, the company’s valuation was approaching $5 billion. Now, the company is valued at $10 billion, according to the Journal.

WeWork started in 2010 and is based in New York. The company has coworking spaces in Austin, Texas; Berkeley, Calif.; Boston; Chicago; Miami; Los Angeles; New York City; Philadelphia; Portland, Ore.; San Francisco; and Washington, D.C. International locations are in Israel, the Netherlands, and the United Kingdom.

WeWork allows individual workers to colocate alongside startups and even teams within larger companies. The startup’s mobile app allows members to book rooms at all of WeWork’s locations.
