Sorry to say this is bad advice and essentially misleading.

"You have sold your previous business or already own a very successful one."

This is of course very true, and probably the #1 factor which will help you raise money, but that's an authentic reason to invest in someone.

No serious fund will give you money because you 'know them' or are the 'son of an important client of some investment bank'.

Graduating from a Top School will be beneficial but it's neither sufficient nor necessary.
