Hi Product Hunt! I'm Brad, a data engineer by trade, and my brother Shawn built Mason Excavating from the ground up with 35+ years of excavation and site work experience. I watched him run jobs where everything looked fine on paper until closeout. One demolition job turned into a significant loss with no real-time visibility to catch it before it was too late. That's why I built GroundMargin. I brought the data engineering, Shawn brought the industry knowledge. The result is job costing software that actually speaks contractor. It understands mobilization, cut yardage, and soil classification instead of generic accounting buckets. QuickBooks tells you what happened. GroundMargin tells you what's happening. The AI estimator is live right now at groundmargin.com. Type any excavation, demolition, or site work job in plain English and get a full cost breakdown in seconds. No login, no credit card. Happy to answer any questions whether you're in construction tech or just curious how AI estimates a demolition job. Would love your feedback. Thanks, Brad
