London-based startup Builder.ai, once valued at $1.5 billion, filed for bankruptcy after it was revealed that its 'AI-powered' platform was operated by human developers from India pretending to be AI.
The startup had raised over $445 million from investors like Microsoft and the Qatar Investment Authority, claiming to make software development as easy as ordering pizza through its AI assistant, 'Natasha.'
In reality, the company was not using AI technology; Indian engineers manually wrote code based on customer requests, while the output was marketed as AI-generated.
The collapse of Builder.ai came in May 2025 when lender Viola Credit seized $37 million due to inflated revenue projections. The company's founder, Sachin Dev Duggal, promised $220 million in sales, but an audit revealed actual revenue was only $50 million.
