Single Source of Truth: How Southern Air's Team Built a 20-Year Software Stack — Then Supercharged It with Claude

Paul Denham is the CEO of Southern Air, a mechanical contracting company founded in 1946 with roughly a thousand employees across three states. They rank near the top 50 mechanical contractors in the country. Their team also builds custom software — has for 20 years — layered on top of enterprise platforms like Viewpoint and Acoro through strong API integrations. The founding principle: if a piece of data exists somewhere, you reference it, you never recreate it. That obsession with a single source of truth drove the team to build a custom interface layer that mirrors how their people actually work. Then Claude supercharged the whole thing — closing the language gap between IT and operations, and powering an AI nameplate reader that identifies equipment at 98–99% accuracy where OCR failed at 60%.
