The Book
A Supercase is based on the idea that when someone learns they have a problem, then they have exactly three options: they can do nothing, they can fix it themselves, or they find a partner to help them.
This book details how that works in the real world.
You can read it as a buyer or a seller, but ideally, you'll read both sides to understand your counterparty's perspective.
" My only ask is that you use this knowledge for good. Don't go ripping off the other side just because I told you what they're thinking."
