Specialized industrial contractor for air separation and cryogenic infrastructure
Maddox Industrial Group operates as a field-heavy industrial contractor focused on air separation, cryogenic systems, and critical infrastructure maintenance. The tech stack is traditional (Windows, CAD, Procore, Salesforce) with no cloud or modern tooling adoption visible, while hiring acceleration is concentrated in construction roles — signaling a scaling play driven by labor-intensive field work rather than software or operational leverage. Active projects around ERP implementation and scheduling system upgrades suggest the company is trying to mature operational infrastructure to support geographic expansion.
