Founded by an experienced lineman
It started with an idea…
Ralph Stinson, a lineman with a 45 year career, was tired of workers climbing to rip down vines with tools not designed to do so. So in 2011 he founded MADI and released the Deviner product. As a lineman and ultimately a crew supervisor, he was able to observe what worked and what needed improvement.
