    Root Causes

    Katerra aimed to revolutionize construction by vertically integrating design, materials, and building—essentially becoming the Apple of construction. SoftBank poured $2B into the vision. But construction is a fundamentally local, relationship-driven industry with thin margins and complex regulations. Katerra tried to do everything at once: build factories, develop software, manufacture materials, and manage construction projects. Quality issues, project delays, and massive overhead consumed cash faster than revenue could grow.
