Like what crypto-projects are these as examples? Do you mean banks that created their own digital coin? I think these projects aren't really considered a crypto project* but they just used the idea of using blockchain technology.
Surely, they know how to manage it properly along the way and understand how it should be run. They are well-knowledge compare to us here and won't risk pushing the project without knowing everything. However, most investors themselves might not interested and it's hard to hype a project without a heavy advertisement or seeking potential big institutional investors and that leads to failure.
