About

On3 builds an AI-enhanced mobile learning and knowledge platform for frontline workers in construction, homebuilding, and manufacturing. Field crews get short instructional video tutorials, step-by-step visual guidance, and an AI assistant that answers questions using the employer's own documented processes, all from a phone on the jobsite. The company was cofounded in 2020 by Paul Cardis and homebuilder Keith Anderson and ships a shared library of more than 1,200 construction learning videos alongside custom video production for subscribing customers. It is based in Madison, Wisconsin.

It is built for jobsite reality rather than desktop LMS use: microlearning video delivered to a worker's phone, plus tooling that captures a veteran tradesperson's expertise on video and turns it into searchable, AI-answerable company knowledge.
