Tech Tidbits: Black Duck,, and TwinStrata Raise Funds

Some sizable tech company financings announced in the past day or so. These are mid-stage or growth-stage companies, not early-stage startups:

TwinStrata, a Natick, MA-based data storage and backup company, closed its Series B round at $8 million, led by Avalon Ventures. Xconomy reported on this round in progress back in August. TwinStrata is led by CEO Nicos Vekiarides. It has the distinction of being one of Boston’s “10 boring tech companies that are actually interesting,” a list I compiled last March.

Black Duck Software, the Waltham, MA-based open source software development company, has raised $12 million led by new investor Split Rock Partners. Its existing investors include General Catalyst Partners, Volition Capital, Flagship Ventures, Focus Ventures, Intel Capital, SAP Ventures, and Red Hat. Black Duck started in 2002 and says it has been cash-flow positive since 2009 (you can read an Xconomy profile from back then here)., the Waltham, MA-based online portal for finding family caregivers, has raised $25 million from investors including New Enterprise Associates, Matrix Partners, and Trinity Ventures. The five-year-old company is led by CEO Sheila Lirio Marcelo, and it raised a $20 million round a year ago.
