Downtobid
AI construction bid management platform that reads plans and specs to automatically send personalized ITBs to subcontractors.
What it does
Downtobid is an AI-native construction bid management platform that automates the invitation-to-bid (ITB) process for general contractors - reading project plans and specifications, identifying the trades required, and automatically generating and sending personalized bid invitations to qualified subcontractors in the GC's network. AI capabilities include automated plan reading that identifies trade scopes from construction documents, AI-powered subcontractor matching that surfaces the best-fit subs based on trade, location, and previous bid history, personalized ITB generation that customizes the invitation content for each subcontractor's relevant scope, and bid coverage analysis that tracks which trades have adequate coverage and flags gaps before bid day.
Why AI-NATIVE
Downtobid is AI-native - automated plan reading to identify trade scopes and AI-driven personalized ITB generation and distribution are the core product capabilities.
Best for
Small general contractors use Downtobid to professionalize their bidding process - AI reading plans and automatically sending ITBs replacing manual scope identification and individual sub outreach.
Mid-market GCs use Downtobid for systematic bid solicitation management - AI handling the repetitive ITB process across multiple concurrent bids so estimators focus on evaluating bids rather than generating invitations.
Limitations
Downtobid's AI matching is only as good as the subcontractor database — GCs with limited sub relationships or those entering new markets see less relevant matching until their sub network is populated.
Automated scope extraction performs best on well-formatted digital construction documents — hand-drawn plans, poor-quality scans, and non-standard document formats yield less complete scope identification.
Downtobid automates ITB distribution and coverage tracking — estimators still need separate tools for takeoff, estimate building, and bid analysis after subs submit their numbers.
