Nebula, the cloud systems company dedicated to enabling all enterprises to easily, securely and inexpensively deploy on-premise private cloud computing infrastructures, announced today that it has closed its Series B financing round.

Providing over $25M of additional equity and debt financing, the new round was led by Comcast Ventures, the venture capital arm of Comcast and NBCUniversal, with significant participation from Highland Capital Partners and included Kleiner Perkins, Innovation Endeavors and industry luminaries Andy Bechtolsheim, David Cheriton and Ram Shriram. Investors that participated include Harris Barton, William Hearst III, Scott McNealy and Maynard Webb. Additionally, Silicon Valley Bank is providing additional debt and credit facilities to the company.

"We're delighted to have the support of investors who have such remarkable track records of success as we continue on our path to make on-premise private cloud computing a reality for all businesses," said Chris C. Kemp, Nebula CEO and co-founder.

Nebula is now powering next-generation cloud infrastructures in market-leading biotech, financial services and media companies in a private beta program that began in March. This investment will allow Nebula to expand the number of companies that will be able to participate in the beta, continue to expand its product and engineering teams, build a petascale test system, and accelerate development and testing of its product.

"We invest in companies that innovate with open source projects and teams that are focused on creating game-changing disruption," said Louis Toth, Managing Director at Comcast Ventures. "After spending several years looking at this market, we are confident that Nebula is the company that will bring private cloud infrastructure to the enterprise."

Nebula, co-founded by former NASA CTO and OpenStack co-founder Chris C. Kemp, has assembled a team of more than 50 engineers inspired by the opportunity to pioneer a new era of enterprise computing. In addition to Dave Withers, former Dell Executive and Senior Vice President of Field Operations, and Jon Mittelhauser, Netscape co-founder and VP of Engineering, Nebula now employs four OpenStack project technical leads, and the engineers responsible for a large percentage of the code in OpenStack.

"We are very excited to have an opportunity to make a significant investment in this round," said Peter Bell, General Partner at Highland Capital Partners. "We believe that Nebula and OpenStack is at the nexus of a historical shift in enterprise computing."
