Cumulus Networks Raises $43 Million in Series D Financing

Cumulus Networks, a leading web-scale networking company, has closed $43 million in new funding in a round led by Telstra Ventures, the investment arm of Australia’s leading telecommunications and technology company. All existing investors, including Andreessen Horowitz, Battery Ventures and Sequoia Capital, participated.

Cumulus Networks plans to lead the effort to bring web-scale networking to enterprise cloud. As a systems solution that fully unlocks the vertical network stacks of the modern data center, Cumulus Linux allows companies of all sizes affordably to build and efficiently to operate their networks like the world’s largest data centers. By allowing operators to use standard hardware components, Cumulus Networks offers operational speed and agility at a competitive cost.

With the new funding, the company will expand its sales force and invest in expanding its marketing programs, with a particular focus on reaching new customers in EMEA and Asia Pacific countries. It will also expand its footprint within Fortune 500 enterprises and service providers, while continuing to focus on bringing innovative networking products to market.
