Digi International Inc.
A maker of industrial Internet-of-Things hardware and software, Digi International builds cellular routers, embedded modules, and connectivity gear used by businesses to link and monitor machines and facilities — managed through platforms like Digi Remote Manager and its SmartSense, Jolt, and Ventus offerings. It started in 1985 as DigiBoard, founded by engineer John Schinas to help early PCs handle multiple terminals. Its clever serial boards famously powered many of the bulletin-board systems that defined the pre-internet era. The company is headquartered in Hopkins, Minnesota.
