A startup selling $1 razors is worth $630 million - and still raking in cash from investors

Dollar Shave Club has raised another $15 million, bringing its latest round of fundraising to almost $91 million, according to an SEC filing posted Friday.

The Series D round was reportedly closed in June when the startup that sells men's shaving kits raised $75 million, led by Technology Crossover Ventures. Friday's filing with the SEC shows that the startup has brought in an additional $15 million with another $10 million worth of shares still up for grabs.

The filing says that a total of 22 investors are participating in the latest fundraising round.

According to Pitchbook, the additional funding raises the valuation of Dollar Shave Club to $630 million.

The Los Angeles-based startup launched in 2011 with an idea to steal market share from razor powerhouse, Gillette. CEO Michael Dubin promised a better price point: for $1 a month, Dollar Shave Club sends you a high-quality razor blades. He created a crude and goofy viral video to support the launch, which garnered 19 million views.

In 2014, the startup says it generated $65 million, triple that of its 2013 revenue, with 2 million monthly and bi-monthly subscribers. Dollar Shave Club did not return request for comment.
