    Root Causes

    Full-stack vertical integration in construction
    Serial acquisitions without integration
    SoftBank enabled decade of losses

    Katerra raised $2B from SoftBank promising to industrialize construction end-to-end — design, manufacture, and assembly. It made a series of expensive acquisitions (KEF Infra, Michael Green Architecture). By 2020 it faced project delays, quality issues, cost overruns, and a fraud scandal at Indian subsidiary Katerra India. SoftBank injected another ~$200M in December 2020 as a lifeline. Katerra filed Chapter 11 on June 6, 2021, one of construction tech's largest failures. Volumod and other creditors bought divisions.

    Key Lessons Learned

    1. Vertical integration compounds risk

    Every layer you own is another way to lose money — pick the layer where you can win.

    2. Acquisitions don't fix strategy

    Katerra bought companies faster than it could integrate operations.
