Root Causes
Builder.ai raised $445M claiming to use AI to build custom apps. In reality, much of the work was done by hundreds of offshore human developers. Internal audits slashed 2023-2024 revenue projections by 75%. The company operated without a CFO since July 2023, and when lenders seized $37 million of its $42 million in cash, it was game over. Founder Sachin Dev Duggal styled himself as "chief wizard." The company filed for bankruptcy in May 2025.
