What KNTRCTR is
KNTRCTR is subcontractor management software for heavy civil and general contractors, focused on organizing bids and tracking subcontractor performance. Prime contractors can post job dates, scope, requirements, and attachments once for invited crews, then compare bids while keeping each original visible. Rex AI scans bids for outliers, missing answers, and past reviews, and can read attachments before an award. It surfaces analysis but leaves the award decision to the user. Invited subcontractors can open a job, ask questions, and submit a bid at no charge. After an award, the job workspace supports contacts, insurance, and a shared checklist. Performance reviews remain double-blind until both sides submit them. KNTRCTR works alongside existing estimating and project management systems, but does not handle estimating takeoffs, project scheduling, or cost control. The first prime-contractor seat is $250 a month, with the first 30 days free; each extra seat is $50 a month. Rex is described in the terms as a beta decision-support feature whose output may be incomplete, inaccurate, outdated, or misleading.
