What happened
It was reported that Builder.ai, a London-based company formerly called Engineer.ai, marketed a platform that it said could assemble most of a software application automatically, fronted by an assistant named Natasha that captured a customer’s requirements. Its founder said the system could build a large share of an app on its own. The company raised around $445 million from investors including Microsoft and the Qatar Investment Authority, reached a valuation of about $1.5 billion, and integrated with Microsoft’s Azure.
It was then reported, as the company collapsed, that the building attributed to the platform had been carried out substantially by human engineers, an estimated 700 of them, working in countries including India and Ukraine, who wrote customers’ software manually. Accounts of how far this went vary, and at least one detailed analysis has argued that the popular “faked AI with 700 engineers” description is overstated, noting that the engineers did real work and that the collapse was driven more by finances than by the human-versus-machine question. What is not in dispute is the money. In late 2024 Builder.ai borrowed from a lender, Viola Credit, which later seized about $37 million from its accounts, and in May 2025 the company entered insolvency proceedings across several jurisdictions. An independent review put its 2024 revenue near $50 million against a figure of about $220 million the company had used, and reporting described allegations of arrangements that inflated the accounts, which were the subject of further scrutiny. The founder had stepped down as chief executive earlier in 2025. Both of the claims the company was built on, how much of the work its software did and how much money it made, turned out to be far smaller than it had said.
What an auditable version would have shown
Builder.ai sold two ideas: that its software could build most of an app, and that the business was earning around $220 million a year. Both turned out to be much smaller than that. Neither had to be taken on faith. A company can record, project by project, which parts of an app its software wrote and which parts a person did. It can tie each sale to a specific invoice. An investor or an auditor can then check both for themselves instead of believing them. Builder.ai’s backers were going on what the company told them, and the real numbers only surfaced once it collapsed and someone went through the books.
Where the gap was
Both of the things that mattered here, what the software did and what the company earned, were things you had to take Builder.ai’s word for. A MetricRecord turns a number like that into a signed figure tied to the events underneath it, so an investor or an auditor can check it themselves. A ConductRecord ties each project to what the software actually did on it, so that “the AI built it” is something you can look up.
What governance should have looked like
If nobody writes down what the software did, there is no way to measure the difference between what it claims and what it delivers. The same goes for the money: a revenue figure that cannot be traced back to individual sales can be stated, but not checked. Best practice would be for a company selling an automated capability to be able to show, from signed records, how much of the work its system really does and how its revenue maps to real invoices, so that the people putting money in can check the numbers instead of trusting them.
Failure Pattern: a company’s claims about what its automated system did and what it earned were taken on its own word, and both were later put far below what it had said.
Governance Principle: a claim about what an automated system does, and the revenue attributed to it, should be verifiable from signed records rather than taken on the seller’s word.
The reference implementation of MetricRecord and ConductRecord is open source. It lives at github.com/saffronandindia/headlights-oss, Apache 2.0 licensed and free to install. The repository is public now.
