Spine
AI estimator and financial OS for specialty subcontractors.
Reads full plan sets and produces a measured, provably complete takeoff and bid — then grows into the subcontractor's financial operating system covering buyout, cost control, billing, and cash. Built for electrical, plumbing, HVAC, drywall, concrete, and mechanical subs, not GCs.
