Nebula, Inc. was a hardware and software company with offices in Mountain View, California, USA and Seattle, Washington, USA. Nebula is the developer of Nebula One, a cloud computing hardware appliance that turns the customer's racks of standard servers into a private cloud. The Nebula One private cloud system is built on the OpenStack open source cloud framework, as well as many other open source software projects.


Nebula was founded as '“Fourth Paradigm Development" in the Spring of 2011 by former NASA Ames Chief Technology Officer Chris C. Kemp, long-time colleague Devin Carlen, and entrepreneur Steve O'Hara.[1]

In May 2011, Nebula closed a round of Series-A investment led by Kleiner Perkins Caufield & Byers and Highland Capital Partners, with participation from Google's first three investors—Andy Bechtolsheim, Ram Shriram, and David Cheriton, as well as other investors.[2]

Nebula's team includes many of the technical project leads on the OpenStack project. In the summer of 2012, eight key members of the original Anso Labs and NASA team that originally wrote the key components of the OpenStack platform joined Nebula.[3]

In the fall of 2012, Nebula closed a $25M Series-B investment led by Comcast Ventures and Highland Capital, and Google co-founder Eric Schmidt’s venture fund Innovation Endeavors became an investor.[4]

Nebula One, Nebula's flagship offering, was made generally available on April 2, 2013.[5]

On April 1, 2015 the company announced on its website and confirmed on Twitter that it was ceasing operations.[6]


In February 2013, SiliconIndia named Nebula CEO Chris C. Kemp as one of ten pioneers in cloud computing.[7]

In March 2013, Nebula was named one of 10 Hot Cloud Companies to Watch.[8]
