Our Founding Story
Our Founding Story
“As a field inspector, I was frustrated by writing notes on paper and re-entering them into CAD—double work that often caused errors. Around that time, news of the Sasago Tunnel collapse, where nine people died, deeply struck me. A victim’s family said, ‘If just one inspector had pointed out the danger, my sister would still be alive.’ That moment made me realize inspections are not just about efficiency, but life and death. It drove me to start my own company. Today, we provide a tablet-based CAD app that eliminates duplicate data entry and reduces human error, with a clear vision: Zero Infrastructure Accident Victims Worldwide.”
