Mirantis just raised $75 million, according to an SEC filing Monday.

Which apparently means there’s a lot of money (correction: a lot of potential) in being a pure-play OpenStack company, because Mirantis closed a $100 million Series B just a year ago.

The company declined to comment on the new funding, but next week happens to be the OpenStack Silicon Valley conference, right in Mirantis’ backyard (the startup is based in Mountain View, California). And that’s followed by VMworld in San Francisco starting Aug. 31.

So the coming weeks provide a couple of appropriate stages for saying something dramatic about the stength and potential of OpenStack. Maybe Mirantis and its investors are just waiting for the right cue.

As of last year, Mirantis was hoping to go public in 2016.
