Venture Rounds at Energetiq, ExtendMedia, Viridity

It’s time for a trio of local funding announcements by way of Private Equity Hub, whose parent company Thomson Reuters has an arrangement with the Securities and Exchange Commission to receive copies of Regulation D filings disclosing changes in stock ownership at privately held companies (a complicated subject unto itself). Frequently, the information on these Reg D filings becomes public before the companies themselves have had time to prepare official announcements—which is no doubt why you haven’t yet seen press releases about any of the following:

* Energetiq, a Woburn, MA, startup that makes short-wavelength light sources for semiconductor and life-sciences applications, has called down $3.8 million of a $5 million Series C round, with Intel Capital, Japan’s Ushio Inc., and Shea Ventures as the main backers.

* ExtendMedia, based in Newton, MA, has collected a $10 million Series C round from existing investors Atlas Venture, Venrock Associates and TVM. We last wrote about ExtendMedia in May.

* Amesbury, MA-based Viridity, a stealth-mode startup working to increase the efficiency and decrease the power consumption of data centers, completed a $7 million Series A funding round. Battery Ventures and North Bridge Venture Partners led the round.
