What Stuppy Greenhouse does

Stuppy Greenhouse is a North Kansas City, Missouri-based manufacturer that designs, engineers, and fabricates custom greenhouse structures and integrated growing systems, founded in 1873 by L.J. Stuppy and operated through five generations of family ownership until its February 2026 acquisition by Atlas Greenhouse. The company sells primarily to commercial growers, educational institutions (where it self-describes as the leading provider for schools and universities), nurseries, retail garden centers, and research/botanical gardens across the United States, with named installations spanning tribal agriculture (Osage Nation $13M facility), municipal gardens (Dallas Arboretum), zoos (Riverbanks Zoo), seed producers (Keithly Williams Seeds), citrus growers (Saxon Becnel & Sons), and K–12 and higher-education programs.

The core product portfolio comprises six structural lines (CS3 A-frame, Rainbow Super, Rainbow Plus, PowerHouse, Pro-Line AeroMax, Polar Series) scaled from roughly 2,000 to over one million square feet, the proprietary Heat2O hydronic heating line (Heat2O-BT bench tube, Heat2O-UBF under-bench fin, floor heating using EPDM tubing and aluminum fins), Mor-Space benching systems, motorized in-house-engineered shade/energy curtains with documented 20–50% heating/cooling savings, and diffused polycarbonate coverings. A construction services line coordinates partner installers and provides as-built drawings and O&M manuals, while an online shop sells accessories and supplies at a $25 minimum order, now hosted on the Atlas commerce platform.

Revenue is generated primarily through one-time project-based sales of custom-engineered structures on a quote basis, supplemented by hardware sales of heating, benching, and accessory products, third-party-financing referral, and installation-services coordination. The go-to-market relies on a five-region US field-sales organization of Regional Sales Managers (Southeast, South Central, North Central, West/Southwest + Pacific Northwest, Great Lakes + Northeast), a dedicated VP of Sales & Marketing, in-house engineers, and dedicated Project Managers per engagement, augmented by presence at ten or more major industry trade shows (MANTS, Cultivate, Farwest, TPIE, World Ag Expo, TNLA, etc.) and a content-marketing program targeting educational and commercial horticulture buyers.
