Literally one of the situations I had to deal with was a non-technical founder who was trying to create a platform for the industry he DID work in.
Had no idea what a "stack" even was, no idea tools or languages would benefit him, got seed funding from a small accelerator, hired a designer to make interactive mocks and chucked them over a fence to a contracting firm in Bangladesh.
Ended up with an unsustainable trash pile of a .NET codebase that was very hard to debug, contractors took the money and ran and refused to fix anything or maintain it. Couldn't litigate or find them because all communication channels were cut off.
We rewrote it completely in Nextjs 🤷♀️
