What the Early Adopters are Saying About Downtobid

"We have used Downtobid for our ITBs and so far our experience has been very positive. It has saved me time on the initial page turn and I really like the number of responses we're starting to see from our subcontractors!"

Robyn LynnMRI Builders

"The first time our company was able to travel outside Atlanta! Bidding in a new market and wasn't getting any hits on Drywall. Requested a boost and with 5 days I had 2 committed bidders and 1 submission. Using them on my next project."

Zalmy KavkaFounder, ZK Builders

""I love, the personalization of it. You get it more directed towards the contractors that we need. You, make it a little more personal than putting it on Blue Book or Planhub or anything like that. You let us communicate with the subcontractors, so we can narrow it down from what you've already narrowed it down from. We get more, more specific, more detailed quotes, more the correct quotes that we're looking for from you guys as opposed to maybe other places.""
