AVTECH is a privately held company with about 100 employees, including 25 at its headquarters in Newport. The company also has sales, service and engineering facilities in Pennsylvania, in Olympia, Wash., and in Sheffield, England, said Michael Sigourney, AVTECH’s senior product specialist.

“We’re a teeny company, but the reason we’re teeny is because we chose to go down a privately funded road, as opposed to getting venture capital,” Sigourney said...

...AVTECH is in the midst of rapid growth, Sigourney said, having grown about 50 percent in sales revenue each quarter for the past seven quarters. The company has relationships with about 1,200 resellers, about 1,100 of which have signed up since January and are learning about AVTECH’s products, he said...

...In anticipation of that growth, AVTECH hopes to expand into the old Sheffield school building in Newport and is currently in discussions with Newport officials and the R.I. Economic Development Corporation to line up funding to buy the building, Sigourney said.
