    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
