Nebula (company)
Nebula, Inc. was a private cloud computing company based in Mountain View, California, with offices in Menlo Park and Seattle. It built Nebula One, a hardware appliance that turns standard servers into a private cloud. The Nebula One system runs on OpenStack and other open-source software.
The company began in March 2011 as Fourth Paradigm Development, founded by Chris C. Kemp (formerly NASA Ames CTO), Devin Carlen, Steve O’Hara, and software engineer Tres Henry (ex-Amazon Web Services, author of the AWS Console). Nebula raised a Series A in 2011 led by Kleiner Perkins Caufield & Byers and Highland Capital Partners, with participation from early Google investors Andy Bechtolsheim, Ram Shriram, and David Cheriton, among others. In 2012, eight members from Anso Labs and the NASA OpenStack team joined Nebula. A $25 million Series B round in fall 2012 was led by Comcast Ventures and Highland Capital Partners, with Innovation Endeavors (Eric Schmidt’s fund) also investing. In March 2013, CIO.com named Nebula one of 10 Hot Cloud Companies to Watch. Nebula One became generally available on April 2, 2013. The company announced it was ceasing operations on April 1, 2015.
