Builder.ai, a UK-based technology startup backed by Microsoft, is facing a collapse following internal investigations that found evidence of potentially fake sales. The company, which has raised over $500 million from investors including Qatar’s sovereign fund, had to revise its revenue estimates to just a quarter of its previous figures. The revelations have cast a shadow over one of the UK’s most funded startups, raising questions about the due diligence practices of its high-profile backers.
