AI Construction Software

Bid Faster, Win More & Build Smarter with the Power of AI.

STACK is the premier AI preconstruction platform where estimating teams complete faster takeoffs, build sharper estimates, and turn every project into measurable revenue, profit, and win-rate growth.

Real Contractors. Real Results.

Revenue Growth

Faster, more accurate estimates mean more bids won and in the pipeline.

Increase in Bids Won

Sharper estimates build client confidence, and confidence wins bids.

Faster Takeoffs

More speed means more bids, and more bids mean more wins.

Thousands of contractors, suppliers and owners trust STACK to bid faster and win more work.

From first takeoff to final build. AI all the way through.

Whether you're evaluating a new bid or working to keep your field crews on track, STACK solutions accelerate your workflows and drive efficiency throughout the construction project lifecycle.

Evaluate

Upload plans and specs. STACK AI reads every sheet, auto-names pages, and flags revisions the moment they land.

Takeoff

Measure linear, area, count, and volume in clicks — with AI auto-counting symbols and suggesting scope you might miss.

Estimate

Quantities flow straight into live estimates. AI pressure-tests pricing while your team works the same numbers in real time.

Build

Carry the same scope and budgets into the field — RFIs, daily reports, photos, and markup keep the build on track without rekeying a thing.
