A regulatory filing seems to confirm reports from the past couple of months that Dropbox has raised a large round of additional funding.
Back in January, the Wall Street Journal said that the cloud storage and sharing company had raised an additional $250 million at a $10 billion valuation. Then, in February, it updated that number to $350 million (at the same valuation) from investors including BlackRock, T. Rowe Price, and Morgan Stanley. However, Dropbox did not confirm the stories.
The filing says that the round could be up to $450 million, with $325 million raised so far. It seems that $350 million is a likely number, since that’s what Fortune has heard, too.
Dropbox had previously raised a little more than $250 million. I’ve reached out to the company and will update if I hear back.
By the way, Dropbox co-founders Drew Houston and Arash Ferdowsi won the founder of the year award at the Crunchies this year, presented by myself and Instagram co-founder Kevin Systrom. (I cropped myself out of the picture above because otherwise it just felt weird.)
Update: Yep, it was $350 million. A source with knowledge of the funding has confirmed to me as well that Dropbox has indeed raised a Series C of that amount from existing investors and major mutual funds at a $10 billion valuation.
