Soladigm, a fairly stealthy green building company based in Santa Rosa, Calif., just brought in $10.6 million, reports VentureWire. This sum breaks down into $4 million in debt and $6.6 million in convertible securities from Khosla Ventures and Sigma Partners.

Very little information is available about Soladigm. According to its web site, it brings together experts in glass, optical coatings and semiconductors to reduce energy consumption in buildings. It is also currently hiring.
