Why We Built These

Every tool started as a spreadsheet or a frustration. We got tired of paying for bloated software that didn't fit how subcontractors actually work.

R
From the Founder

"I spent years running masonry crews and trying every project management tool out there. They were all built for GCs. The spec analyzer came from spending 4 hours on a Saturday reading through a 2,400 page spec book. The header tracker came from my Excel sheet that I'd been using for 10 years. These tools exist because we needed them ourselves."

— Ryan, PM4Subs Founder
