A stealthy, Boston-based startup with under 10 employees just pocketed a sizable funding round to kickstart its business.

ClearSky Data has closed a $12 million funding round from Highland Capital Partners and General Catalyst, reports Founded by Ellen Rubin and Lazarus Vekiarides, who met last year, the startup is currently operating out of Highland’s Kendall Square offices, though it’s looking for its own office space elsewhere in Boston.

We’re not entirely sure what the company is doing, though it’s hiring people with experience in security, storage, networking, and virtualization. Rubin said the company is solving an enterprise infrastructure problem for medium and large enterprises, and that it leverages both their backgrounds “in a really exciting way.”

Rubin has expertise in cloud computing, business intelligence, data warehousing, and data center markets. She previously worked at data warehousing company Netezza, and later cofounded cloud migration company CloudSwitch, which Verizon acquired in 2011.
