and yet groups (including Microsoft?) were still investing in it in 2023:
Between 2018 and 2023, Builder.ai secured an impressive $445 million in VC funding. Backers included high-profile investors like Microsoft and the Qatar Investment Authority (QIA).
Microsofts involvement elevated the company to unicorn status, with Builder.ai securing a valuation of $1.5bn in 2023, as well as global recognition as a leading AI innovator.

A 2019 report in the Wall Street Journal burst Builder.ais (then known as Engineer.ai) bubble by debunking its claims to use AI for software development. It turned out that the app was largely powered by an assembly line of human developers in India, responding to user requests in real-time. The promise of AI-powered app development was a gimmick.
This revelation, combined with claims of fake customer reviews and logos of companies they hadnt worked with advertised on their site, left a stain on Builder.ais reputation.
