I've worked at a couple of startups that have operated like this. They had vaporware products, and were focused more on getting money out of investors than they were brining a product to market. I arrive and realize that the code quality is absolutely terrible, and worse, the approach they've decided to take is simply never going to work. I report a list of problems to the CEO, tell them they won't be launching in six months, and that the fastest way for them to get a functional product would actually be to throw everything away and start again.

This makes the CEO angry, because they don't care if they have a working product. They only care about having a good story to tell investors. This makes the existing technical leadership angry, because they don't know how to do things properly, so having somebody say they're doing it wrong is obviously a big issue for them. In fact, the only reason they're in technical leadership positions to begin with is because the startup decided to cheap out and hire people with 2 years experience working in body shops as "tech leads". I realize the company can't be fixed so I leave, and the company folds once it reaches the end of it's runway.

Companies like this aren't terribly uncommon, and they exist primarily to defraud inexperienced investors. FWIW, I've seen this play out at every blockchain startup I've contracted at.

I'd love to but I've signed NDAs for the companies I've worked for.

If you like advertising that will put on the right path.
