What Roberts-Hamilton Company, Hajoca Corporation does

Roberts-Hamilton Company is a regional wholesale plumbing, heating, HVAC, and industrial supplies distributor serving Minnesota contractors, plumbers, industrial buyers, and DIY customers since 1898. The company operates as a wholly-owned subsidiary of Hajoca Corporation, a large national wholesale distributor, and runs four physical branch locations in Fridley (headquarters), Eagan, Waconia, and Rochester, stocking 8,000+ plumbing and heating SKUs across categories including fixtures, faucets, fittings, water heaters, hydronic/HVAC equipment, valves, and industrial supplies. Roberts-Hamilton distributes major manufacturer brands including Kohler, Moen, Delta, Rheem, Bradford White, Rinnai, Navien, and Viega, and monetizes primarily through wholesale hardware sales with project-quote-based B2B pricing plus ancillary transactional fees from ROHACO Express, a $75/$100 metro delivery and installation service for residential water heaters and softeners.

The company's underlying technology is centered on SupplyWeb, a proprietary 24/7 B2B e-commerce platform available via desktop and iOS/Android mobile apps (SupplyZone), which supports online ordering, quotation management, spec sheet access, inventory checking, and invoice tracking. The go-to-market blends enterprise field sales through the branch network, inside sales support during business hours, and self-serve online ordering, with additional demand-generation tied to residential rebate partnerships with Xcel Energy and CenterPoint Energy. Roberts-Hamilton is privately held under Hajoca Corporation, which is itself a privately-held conglomerate; no external investors, funding rounds, or public-market signals are disclosed in the available data.
