OpenStack hardware startup Nebula Inc. is no more with an announcement Thursday that it had ceased trading.

Self-proclaimed as the “world’s first enterprise cloud computer” provider, Nebula offered a product that allowed businesses to easily, securely, and inexpensively deploy large private cloud computing infrastructures.

The company developed a hardware appliance called Nebula One that allowed any business to easily build a massive private computing cloud from hundreds or thousands of inexpensive computers, or as we described back in April 2013, a “turnkey solution that can transform an ordinary bunch of servers into a cloud platform running OpenStack.”

Nebula was founded by Former NASA Chief Technology Officer Chris Kemp, and during its existence managed to attract talent from the likes of Rackspace, among others.

In a statement on the main page, the company said that “this is a difficult announcement for us to make and we want to assure our customers, shareholders, and employees that we have worked hard to explore alternatives and exhausted all potential options.”

Interestingly after stating that they were “incredibly proud of the role we had in establishing Nebula as the leading enterprise cloud computing platform” they then went on to blame the market, versus their own management failings for their closure, saying that they were “deeply disappointed that the market will likely take another several years to mature” and further that “as a venture backed start-up, we did not have the resources to wait.”

The good news for customers is that deployed Nebula private clouds will continue to operate normally, however with the company closing, support will no longer be available.

The company noted that given its product is based on OpenStack, it is compatible with OpenStack products from vendors including Red Hat, IBM, HP and others, giving its customers a number of choices moving forward.

Nebula managed to burn $38.5 million in venture capital prior to its closure, from investors including Webb Investment Network, Comcast Ventures, Scott McNealy, William Hearts II, Kleiner Perkins Caufield & Byers, Highland Capital Partners, and others.
