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.

Between 2007 and 2014, I was a staff editor for Xconomy in Boston and San Francisco. Since 2008 I've been writing a weekly opinion/review column called VOX: The Voice of Xperience. (From 2008 to 2013 the column was known as World Wide Wade.) I've been writing about science and technology professionally since 1994. Before joining Xconomy in 2007, I was a staff member at MIT’s Technology Review from 2001 to 2006, serving as senior editor, San Francisco bureau chief, and executive editor of TechnologyReview.com. Before that, I was the Boston bureau reporter for Science, managing editor of supercomputing publications at NASA Ames Research Center, and Web editor at e-book pioneer NuvoMedia. I have a B.A. in the history of science from Harvard College and a PhD in the history and social study of science and technology from MIT. I've published articles in Science, Technology Review, IEEE Spectrum, Encyclopaedia Brittanica, Technology and Culture, Alaska Airlines Magazine, and World Business, and I've been a guest of NPR, CNN, CNBC, NECN, WGBH and the PBS NewsHour. I'm a frequent conference participant and enjoy opportunities to moderate panel discussions and on-stage chats.
