What STACK Construction Technologies does
STACK Construction Technologies is a cloud-based construction software company founded in 2010 and headquartered in Cincinnati, Ohio, serving the preconstruction through project closeout lifecycle for the construction industry. The platform is organized around two core solutions—Takeoff & Estimate and Build & Operate—delivering digital quantity takeoff, cost estimating, plan and specification management, document control, field collaboration, and project management, with a companion mobile field app available on iOS, Android, and Windows. Underlying technology includes AI-powered OCR for construction plans, AI-assisted takeoff measurements (AI Takeoffs), an Advanced Plan Search retrieval feature, and STACK Assist as a generative AI assistant, complemented by integrations with construction platforms (Procore, Autodesk), ERP/accounting systems (Acumatica, Sage, QuickBooks), CRM, and a partner marketplace (STACK Exchange). STACK monetizes primarily through tiered subscription licensing (freemium trial, paid monthly subscriptions, enterprise annual contracts with SSO and API access) supplemented by training and professional services, and acquires customers via product-led growth, direct enterprise sales, and a channel network of VARs and technology partners. The customer base spans thousands of specialty contractors, general contractors, suppliers/distributors, and owners/developers across the US and Canada, including enterprise accounts such as Kiewit, Siemens, PCL Construction, Tetra Tech, HydroQuebec, and NYPA. The company is privately held, has raised roughly $29.3M in disclosed funding led by Level Equity Management and CincyTech, acquired SmartUse Solutions in 2021, and appointed Viyas Sundaram as CEO in March 2026 to lead the next phase of AI-driven innovation.
