An SEC filing reported by MarketBrief has revealed that Minneapolis-based enStratus Networks has raised $3.5 million in venture capital. The total size of the round is $4.5 million, a reliable source told me, but the investor for the additional $1 million has not yet been announced. 
Founded in 2009, enStratus provides a cloud infrastructure management solution for deploying and managing enterprise-class applications in public, private, and hybrid clouds. It counts among its customers Korea Telcom (KT), SAIC, Predictix, Quantum Retail, and The Cloud Security Alliance.
I confirmed that the lead investor is El Dorado Ventures of Menlo Park, California. General Partner Jeff Hinck, based here in Minneapolis, is joining the enStratus board of directors.
More to come as I learn about it, which will likely be next week, in conjunction with enStratus’ appearances at two key industry events: Defrag in Denver and Cloud Expo in Santa Clara.
In another recent enStratus development, James Urquhart, a cloud strategist and evangelist at Cisco, revealed on his Twitter page on October 28 that he would be leaving Cisco to join enStratus as VP of Product Strategy.
UPDATE: I confirmed this morning (Nov 4) that the SEC filing only appeared yesterday as the result of an accidental early submission. A formal news release from enStratus announcing the Series A may come as early as Monday, presumably identifying the other investor.
