Father, son, and a shop problem.
Mark Tolley runs Sanctum Screens, a metal fabrication shop in Queensland, Australia. Mark and his team build gates, fences, and screens for homes and small commercial jobs.
Every quote needed a drawing. Every drawing took hours. Numbers got missed. Jobs got remade. The same problem came back every week.
His son, Harry Tolley, builds software. They put the problem and the fix together. The result is CAD60.
