About StringBean Technologies

Born out of the Industry

StringBean started as the vision of an industry insider stymied by the inefficiencies and lack of accountability across his field service business. Nearly half a million dollars a year on administrative staff compiling field data and creating reports wasn’t working. He was wasting time and money on resources that only slowed him down. That’s when he sat down with an old friend and tech entrepreneur to put pen to napkin and bring StringBean to the industry.
