Builder.ai, a London-based AI startup once valued at $1.5 billion and backed by Microsoft, has filed for bankruptcy after being exposed for falsely marketing its app-building services as AI-powered.
Investigations revealed that the company’s touted AI assistant, “Natasha,” was largely a façade—most of the work was done manually by 700 engineers based in India. Additionally, Builder.ai engaged in financial misconduct through “round-tripping” with VerSe Innovation to inflate its revenue figures.
The company claimed $220 million in 2024 sales, but audits showed only $50 million. The scandal has reignited concerns over AI hype and transparency in the tech startup ecosystem.
- Builder.ai filed for bankruptcy: Yes, Builder.ai has indeed filed for bankruptcy (specifically Chapter 7 in a Delaware court for its main US holding company, and also entered insolvency proceedings in the UK) around early June 2025 (or late May, depending on the specific entity/jurisdiction mentioned in reports). This occurred after creditors reportedly seized most of the company’s funds.
- London-based AI startup once valued at $1.5 billion and backed by Microsoft: This is also correct. Builder.ai was indeed a London-based AI startup that achieved a valuation of around $1.5 billion (or near-unicorn status at $1 billion+) and had significant backing from investors, including Microsoft, the Qatar Investment Authority, and SoftBank.
- Falsely marketing its app-building services as AI-powered; “Natasha” largely a façade, with most work done manually by 700 engineers based in India: This claim is widely reported and a central part of the scandal. Investigations and former employee accounts indicate that while Builder.ai marketed “Natasha” as an AI assistant capable of autonomously building apps, a significant portion, if not most, of the actual development work was performed manually by human engineers, primarily based in India. This discrepancy between marketing and actual operations has been a major point of contention.
- Engaged in financial misconduct through “round-tripping” with VerSe Innovation to inflate its revenue figures: Allegations of “round-tripping” with Indian social media company VerSe Innovation (parent of Dailyhunt and Josh) have been widely reported. This involved accusations that the two companies exchanged inflated invoices for non-existent services to artificially boost their revenue figures. VerSe Innovation, however, has publicly denied these allegations, stating that all transactions were for legitimate business services and supported by documentation.
- Claimed $220 million in 2024 sales, but audits showed only $50 million: Reports indicate that Builder.ai had to restate its past financial figures. While specific numbers vary slightly across reports, it’s consistent that the company had significantly overstated its projected or reported revenues. Some reports mention that the claimed 2024 sales projection was overstated by 300%, leading to actual figures being much lower (e.g., actual revenue closer to $50-55 million rather than the claimed $220 million).
- Scandal has reignited concerns over AI hype and transparency: This is a key takeaway from the situation. The collapse of Builder.ai is indeed being cited as a high-profile example of the risks associated with AI hype, overvaluation, and lack of transparency in the tech startup ecosystem, prompting increased scrutiny from investors and regulators.
