Computer network server company Cisco Systems and Swisscom Ventures, the corporate venturing unit of the eponymous Swiss phone operator, have invested in a $8m series B round for US-based cloud computer operation system Piston Cloud Computing.
There was also involvement from non-profit search provider Data Collective and venture capital firms Divergent Ventures, Hummer Winblad and True Ventures.
The new funds will be used to drive product development and meet the needs of its growing customer base.
The community of OpenStack has grown to nearly 7,000 from a range of 87 countries.
In July 2011 Piston raised $4.5m in a series A round from True Ventures and Hummer Winblad. The company received $500,000 in seed funding in March the same year.
Piston recently appointed Jim Morrisoe as chief executive.
Morrisoe said: “Our investors’ confidence in Piston Cloud validates our strategy and the pioneering work we have done over the last two plus years in the OpenStack community, this new investment will enable us to build on this foundation and to accelerate our growth as we work to enhance our products, grow our customer base and establish new partnerships.”
