KG Technologies
Cotati, Calif.

No. 49
2010 Revenue: $40.7 million
Three-Year Growth: 3,920%

KG Technologies makes relays, switches that allow electric companies to turn their meters off remotely. This means unoccupied buildings can be shut off without wasting gas on a technician trip. As more countries join the so-called smart grid trend, KG Technologies reaps the benefits. In 2010, 50 percent of KG’s revenue came from overseas, and there’s still plenty of room to grow. By 2020, all homes in the European Union will be required to be on the smart grid.
