The ROI of Estimating Accuracy: How STACK Customers are Winning More
Consistent estimating accuracy builds confidence, speeds up bidding, and drives more profitable wins. STACK customers are proving this every day with higher win rates and revenue growth.
Your AI Gateway in Preconstruction.
Takeoffs. Estimates. Project data... Just ask.
STACK IQ works inside the AI tools you already use, like Claude, ChatGPT, and more. Just ask and let STACK do the work.
STACK IQ
Your AI. Your workflow. Your data. STACK is already there.
STACK IQ connects the AI you already use and trust to operate STACK. Modify a takeoff, check an estimate, analyze project data, or connect the rest of your tech stack — all from a single prompt in AI tools like Claude, ChatGPT, and more!
Measure and bid more work in less time
Tasks that took an afternoon now just take a sentence, so the jobs you used to pass on are back on the table.
Price from history, not your memory
Your last 50 projects become the numbers you bid with... down to the line item.
Connect all your tools seamlessly
Word, Excel, PowerPoint, Monday.com — your numbers land where the rest of your team already works.
Get answers from anywhere in seconds
Your AI is already on your phone, so STACK is too — ask from the truck or the jobsite and have the number before you reach the trailer.
How it works:
Connect your AI
Connect the STACK MCP in the AI tool you use most — Claude, ChatGPT, and more!
Type your prompt
Open your AI and ask STACK for whatever you need.
Watch it work!
Answers, suggestions, automations... no limit to what you can accomplish.

AI can't read the room.
STACK IQ can read your cost history, your quantities, and your last bid — in seconds.
AI can't replace the estimator who's been doing takeoffs for 20 years.
STACK IQ can enable them to do the work of three people.
What STACK IQ Insiders are saying:
"We've been transitioning our bids from Excel to building them directly in STACK. We're creating master proposals, which is now possible through STACK IQ. It takes things to the next level and I'm excited to see what comes next."
"STACK IQ has taken our estimating to a whole new level. It allows us to produce estimates, proposals, and budgets off one prompt. We are able to identify discrepancies in estimates and revamp our document formatting from "similar" to identical and repeatable."
"STACK IQ has been a great addition to our estimating toolkit. It has allowed our estimating department the ability to further hone and refine our process. We are grateful to the whole team at STACK for helping put better tools at our fingertips."
