Cumulus Networks is emerging as one of hottest Software Defined Networking (SDN) startups with a valuation recently estimated in the $300 million range, according to research by the Rayno Report that will be released next month in our exclusive SDN Startup report.
The high-profile deal with Dell announced in January was the key driver for Cumulus, with that partnership already producing revenue in some key data-center accounts. That helped catapult Cumulus to the next level and probably gives it the most momentum of any SDN startup. Cumulus has raised $51 million total and is backed by Andreessen Horowitz, Battery Ventures, Sequoia Capital, and Wing Ventures.
It's clear that Cumulus, with its model of de-coupling the networking operating system from the hardware, is now perceived as one of the leaders in the SDN startup market, according to a number of sources in the industry, including venture capitalists and executives. I'll be ranking Cumulus among a group of at least 12 companies when when I release my SDN Startup report next month. It will have a price, which has yet to be determined. The free analytics report is still available here.
