Posted on by SHAKEEL.RASHED

Builder.ai, a UK-based AI startup aiming to simplify app development, faced a high-profile collapse in 2025. Reports indicate concerns over inflated sales projections, leading to the ousting of its founder and CEO, Sachin Dev Duggal, in February 2025. The company’s failure has raised concerns about the UK’s AI sector and its ability to compete globally. Investors, including those from Qatar, reportedly realized the company’s revenues were largely artificial, contributing to its downfall. Here is a founder giving an interview with Bloomberg of their raise from the Sovereign wealth fund.
