Our History

LineVision is a new company built on a foundation of over 15 years of research, development, field testing and utility validation in the area of non-contact transmission line monitoring.

2005-2014 The Promethean years

Promethean Devices pioneered and patented the non-contact monitoring of transmission lines, and validated this technology through close cooperation with utilities including ONCOR, Southern Company and ConEd. Stephen Syracuse, PhD led Promethean during these years and continues to be a trusted advisor to LineVision.

2015-2017 The Genscape years 

Genscape acquired Promethean devices in 2015, refined the technology and completed several successful pilot programs with transmission line owners and regional grid operators. Genscape continues to support LineVision as a shareholder, supplier and strategic partner. 

2018 LineVision's launch 

The spinout of LineVision in May of 2018 creates a new company dedicated to improving the state of the art in Transmission Line asset monitoring and asset management for utilities worldwide.


The Founding Team Jon, Nate and Hudson share an intense foosball rivalry, a prodigious collection of bikes, and a passion for developing advanced sensors and analytics which help utilities gain valuable operational and asset management data on their transmission lines
