Geoff Letcher, owner of Pukekohe-based Quadbeam Technologies, was a lonesome but successful salesman.

Quadbeam’s Suspended Solids Sensor is now sold in 14 countries – and Letcher’s hours of door-knocking in faraway places has paid off.

"The market has changed rapidly. Where people didn’t want to talk to us, we now have them calling us," says Letcher, whose family bought Quadbeam in late 2009.

"It’s been 'bloody' hard work. A lot of travelling and a lot of cold calling and finally we are a good news story.

"The business has grown three times since 2009 and I expect it to more than double by mid-2019,’" says Letcher.
