Revit's 30-Year Monopoly: Why the $13 Trillion AEC Industry Still Runs on 1997 Software

The architecture, engineering, and construction (AEC) industry, worth $13 trillion annually, remains dominated by Revit, software built in 1997 that now commands 95% market share. Despite being a monopoly tool with outdated collaboration features, Revit's entrenchment through education, proprietary file formats, and lock-in of decades of project libraries has prevented meaningful disruption. Recent advances in LLMs and vision models now present an opportunity to finally challenge the status quo.
