The problem
Commissioning custom software is slow and expensive, and no-code tools rarely stretch to real products — a gap an ‘AI that builds your app’ story filled perfectly.
Why it worked (or didn’t)
It didn’t. Builder.ai raised more than $450 million, including a $250 million Series D in May 2023 led by the Qatar Investment Authority with Iconiq Capital, Jungle Ventures and Insight Partners, on claimed 2.3x revenue growth — and added a strategic Microsoft collaboration putting its ‘Natasha’ AI inside Teams. In May 2025 the company slipped into insolvency after an internal review uncovered evidence of potentially bogus sales, and reported revenues were revised down to just 25% of previous estimates. Once valued above $1 billion, it became the Gulf sovereign-backed AI boom’s biggest cautionary tale.
Challenges
Fabricated-sales allegations destroyed creditor trust and triggered the insolvency; due diligence had missed what an internal review later found; and US prosecutors subpoenaed the former finance chief, keeping the legal fallout alive long after the money ran out.
Funding
- Raised: $250M Series D (May 2023), led by QIA; more than $450M raised in total (TechCrunch).

- Status: closed — insolvent since May 2025.
Latest — October 2025
US prosecutors subpoenaed Builder.ai’s former finance chief as part of a grand-jury probe into the collapse — the saga moved from boardroom failure to criminal-justice territory, with QIA and Microsoft left among the biggest names nursing losses.
