Plexxi Pulls In $20M More for Mysterious Networking Tech

Plexxi, an aggravatingly stealthy networking startup in Nashua, NH, said today it has raised a $20 million Series B equity round led by Lightspeed Venture Partners. Previous investors Matrix Partners and North Bridge Venture Partners also participated in the financing. The company has raised a little over $28 million to date.

According to its sparse website, the company is trying to solve “the problems faced in building state-of-the-art enterprise and cloud datacenter networks with 20th-century networking technology.”

So it sounds like the team is working on a more efficient technology to help businesses and IT departments manage the growing mess that is the modern data center. Beyond that, your guess is as good as mine.

Plexxi is led by founders Dave Husak (formerly of Reva Systems) and Ephraim Dobbins (formerly at Acme Packet). Perhaps their past companies serve as clues to what the future holds.
