STACK Construction Technologies

STACK Construction Technologies builds cloud preconstruction and field software from Cincinnati, with a second office in Longueuil, Quebec. The core products are takeoff and estimating, including AI-assisted takeoff, integrated estimating, a STACK for Excel connector and ERP integrations, alongside Build and Operate tools covering mobile plan viewing, daily reports, punch lists and workflows. The customer base spans specialty contractors, general contractors, suppliers and manufacturers, and owners and developers, with firms including Kiewit, PCL, Pomerleau and Hydro-Quebec among those listed on its site. In September 2026 the company published a Censuswide survey of 500 U.S. construction workers aged 18 to 35, reporting that 75% had received no formal training.

Pricing is published on the site rather than gated behind a sales call. Three ways to buy are listed: Takeoff & Estimate starting at $249 per user per month, Build & Operate starting at $49 per user per month, and the full platform starting at $298 per user per month, with a build-your-price option for teams that mix the two. The takeoff tier has a free version, and Build & Operate includes a two-week complimentary trial for new users. Because everything is billed per seat, an estimating department of four and a field organization of sixty scale on very different curves, and the field tier is priced low enough to hand to foremen who only need plans, issues and daily reports.

The integration list is where this stops being a standalone takeoff tool. Accounting and ERP connections cover Acumatica, Oracle NetSuite, Sage Intacct, QuickBooks Desktop and QuickBooks Online. Procore appears twice, once on the preconstruction side and once for construction. Drawing sources include Autodesk Vault, BidCentral and the Dodge Data & Analytics plan room. CRM links run to FollowUp CRM and TopBuilder, BNi supplies cost data, and Nearmap contributes aerial imagery. Workpack, Ediphi and Velixo extend takeoff, estimating and the Excel connector respectively, and a developer portal offers direct API access for teams building their own pipelines.

Trade coverage is spelled out rather than implied. Concrete, masonry, drywall, electrical, framing, insulation, mechanical, painting, plumbing, roofing and site work each get their own entry, which is how a prospective buyer confirms their scope is modeled before committing to a trial.

Support comes bundled rather than sold as a tier. Customers get a help content library, live and pre-recorded webinars, in-app chat, phone support and email access to an account manager. STACK IQ sits on the product menu alongside AI Takeoff, integrated estimating, the Excel connector and the field app, so the AI work lives inside the existing estimating flow rather than as a separate purchase.

The office is at 9999 Carver Road, Suite 300, in Cincinnati. The company frames its origin as solving problems from the back office through to the field with cloud tools, and names innovation, teamwork and transparency as the principles behind how it builds products and supports customers.
