Piston Cloud Computing Scores $4.5 Million In Funding For Open Source Cloud


Piston Cloud Computing, a software company developing commercialized OpenStack software for businesses, has raised $4.5 million in funding in a round led by Hummer Winblad and True Ventures, with Divergent Ventures and others participating.

Lars Leckie from Hummer Winblad, and Puneet Agarwal from True Ventures will join Piston’s board of directors.

Launched by NASA and Rackspace in 2010, OpenStack is the fastest-growing open-source project in the world, with over 1,100 contributors and 82 participating companies, including Rackspace, NASA, Citrix, Intel, Cisco, Arista Networks and Dell.

Piston’s co-founders actually came from the technical teams at NASA and Rackspace, and helped to create the OpenStack project in 2010.

Piston’s CEO, Joshua McKenty, was the Cloud Architect of NASA’s Nebula Cloud infrastructure, the precursor of OpenStack’s cloud computing component, and holds an appointed seat on OpenStack’s Policy Board.

Piston’s CTO, Christopher MacGown, was a Technical Lead at SliceHost, acquired by Rackspace in 2008. In addition, the team has recruited some of the best talent from the OpenStack community, including core contributors from NASA and other participating organizations.

Piston Cloud technology is currently in limited beta, with a public release expected in Q4 2011.
