Rebuilding How GCs and Subs Connect

Back then, GCs and subs walked the site together. Questions got answered on the spot. Everyone left knowing they were pricing the same work
‍
Then bidding moved online. Suddenly it's 50 portals, 200 emails, and nobody's sure if they're looking at the right drawings. GCs blast the same generic invite to everyone. Subs wonder if it's even a real job. The whole thing feels like spam.

We built Downtobid to bring back what worked—just digitally.
Real relationships, clear communication, everyone on the same page. When GCs can send clean scopes from their own email and subs can track everything in one place, that trust comes back. Bids get tighter. Projects start smoother.
