Problem
Commercial construction bidding has fragmented across dozens of portals and hundreds of emails, leaving GCs blasting generic invites and subs unsure if they are pricing the right drawings. This breakdown in communication creates confusion, missed deadlines, and a general sense that the process feels like spam, eroding the trust that once defined GC-sub relationships.
Solution
Downtobid provides an AI-powered construction bidding platform that rebuilds the GC-sub connection digitally. GCs upload plans and the AI reads every sheet, identifies trade packages, and drafts clean scopes and notes automatically. The platform then sends personalized ITBs from the GC's own email, ensuring each sub receives their specific scope with clear notes rather than a generic blast. Subs get a unified board showing every invite, deadline, and RFI, so they can reply before competitors even open theirs. Real-time tracking shows who has opened bids, who is bidding, and who needs a nudge, bringing clarity and trust back to the process.
Target Audience
Primary users are commercial general contractors who need to build bid packages and send ITBs efficiently, and subcontractors who need a single board to track and respond to bid opportunities.
