Boston Roundup: Sqrrl, Panorama, Superpedestrian, Threat Stack, & More

[Updated 11:25 am]
We’ve got a flurry of fundraising news to round out the week, along with word of some venture partner departures:

Sqrrl, a secure database software company founded by former National Security Agency computer scientists, has raised $5.2 million in Series A financing. The investment was led by Atlas Venture and Matrix Partners, both of whom were previous backers. Earlier this year, Sqrrl hired a new CEO, former F5 Networks executive Mark Terenzoni.

—Cambridge-based Panorama Education, a developer of data analysis and survey software for K-12 schools, has raised $4 million from a collection of notable investors. The seed funding was led by SoftTechVC and Startup:Education, the $100 million foundation started by Facebook founder Mark Zuckerberg. Other investors include Google Ventures, actor Ashton Kutcher, and Yale University. Panorama says some 4,000 schools use its products.

Superpedestrian, a Boston-based MIT spinout working on a power-assist wheel for bikes, has raised $2.1 million from Spark Capital and Tumblr founder David Karp. The startup’s device, known as the Copenhagen Wheel, is concealed beneath a disc-shaped housing on a bike’s rear wheel. It stores energy spent while braking in small batteries, which then drive the wheel during hill climbs or other difficult conditions.

Threat Stack, a startup working on security software for cloud servers, has raised $1.2 million in seed funding. The money comes from Atlas Venture and .406 Ventures. Threat Stack, which was part of the TechStars cloud accelerator program in San Antonio, recently moved to Cambridge from the Washington, DC area.

NBD Nanotechnologies, a 2012 TechStars Boston graduate that is working on nanotech coatings for industrial uses, has filed paperwork for a $1.2 million equity and debt financing round. The startup’s technology uses a combination of advanced materials that can attract or repel water, mimicking behaviors seen in nature.

Ovuline, a startup working on pregnancy-tracking software, has raised about $1.25 million in additional financing. The investment brings the startup’s total capital raised to about $2.75 million, CEO Paris Wallace says. The money came from previous investors, including Lightbank and TechStars CEO David Cohen’s Bullet Time Ventures. Ovuline also was a 2012 TechStars Boston company.

—ByteLight, a startup that hopes to help retailers track shopper location using LEDs, has raised another $3 million. The startup raised about $1.2 million a year ago. [Added this item.]

North Bridge Venture Partners has lost two partners, according to a report in Fortune. Dan Primack reports that Basil Horangic and Bill Geary are no longer with the firm as it gears up to raise an eighth early stage venture fund. North Bridge also was in the news this week after raising $580 million for its second growth equity fund. Geary is joining Foundation Medical Partners, a Connecticut-based health-technology venture firm that now has a Boston office. Also joining Foundation as a general partner is Michael Greeley, who had been a general partner at Flybridge Capital Partners. [Added Foundation note.]
