Boston Tech Roundup: Predilytics, Altaeros, Threat Stack, Next Step Living

An interesting cross-section of companies have reported new private investment in recent days around the Boston area, including startups that deal with digital security, clean energy, and medical data:

—Predilytics, a Burlington, MA-based seller of predictive data analytics for healthcare, has raised another $8.9 million in investment, according to an SEC filing. The paperwork also indicates the equity investment round could grow to $10 million. Predilytics last raised a $4.5 million round of financing in September 2013. Its previous backers include Google Ventures, Highland Capital Partners, Flybridge Capital Partners, and Foundation Medical Partners.

—Altaeros Energies, an MIT-bred developer of airborne wind turbines, has raised $7 million from Japan’s SoftBank Corp. The startup, based at Somerville, MA’s Greentown Labs, says its wind turbines can capture higher-velocity wind because they float up to 2,000 feet off the ground. Previous funding has come from a variety of government and private sources.

—Threat Stack, a Cambridge, MA-based company that provides security monitoring software for cloud-computing systems, has raised another $5 million from previous backers Atlas Venture and .406 Ventures. The company, co-founded by chief scientist Jen Andre, launched publicly in November at Amazon Web Services’ prominent re:Invent conference.

—Next Step Living, a Boston-based provider of home energy-efficiency audits, has filed SEC paperwork for an additional $4 million in equity investment. It’s the second time Next Step Living has added to an investment originally announced as a $25 million Series D round in June. The total now stands at $33.6 million.
