Ironwood, Arctic Sand, Novogy, Moontoast, & More Boston-Area Deals

Fundraising deals big and small have been cropping up around the Boston area in the past week, and they’re spread across pharma, semiconductors, clean energy, and software:

Ironwood Pharmaceuticals of Cambridge says it has raised $175 million in debt financing, as seen in a recent filing with federal regulators. Ironwood discussed that news as part of its fourth-quarter earnings release, which also noted net sales of $19.2 million in the quarter for linaclotide (Linzess), its drug for constipation and irritable bowel syndrome. Ironwood (NASDAQ: [[ticker:IRWD]]) got the regulatory go-ahead to start marketing linaclotide last year.

—MIT spin-out Artic Sand Technologies has polished off a $9.6 million Series A fundraising round. Investors included Arsenal Venture Partners, Northwater Capital, Dialog Semiconductor, Energy Technology Ventures, and Ray Stata. Cambridge-based Arctic Sand develops power converter chips that are designed to cut down on the electricity needed to run traditional data centers. It had raised about $6.6 million of the round in mid-2012.

—Clean-energy startup Novogy has raised about $6.3 million through equity sales, according to a filing with the SEC. The Boston Business Journal notes that Novogy is attempting to make biofuels from waste paper—a kind of fuel known as “cellulosic” biofuel, since it is based on cellulose plant fibers rather than sugars.

—Boston’s Moontoast, a startup working on social-media advertising software, says it has raised $5 million in a Series B round. The investment was led by The Martin Companies, which also was an investor in Moontoast’s $6 million fundraising a year ago. Moontoast is also partially based in Nashville.

—Burlington, MA-based RedShift Systems says it has raised $3 millionin a third round of VC financing. The company works with lasers, particularly in making infrared filters for use in spectroscopes. The new round was led by Technology Venture Partners. RedShift raised a $6 million round in 2009.
