My brother build something quick and dirty in Delphi for his company in 4 hours, back in 2016. It was supposed to be a stopgap for 3 months until the real developers (he is in infrastructure, but used to write in Delphi 25 years ago) will write a "proper" app. 3 years later the developers said it will take 3 months for 4 people to write it, so they were denied. App still running today. Company with over 1 billion in yearly sales.
