Marc Andreessen on identifying fake people:
“You ask increasingly detailed questions and people have trouble making things up and things just fuzz into obvious BS, and fake founders basically have the same problem. They’re able to relay a conceptual theory of what they’re doing… But as they get into the details, it just fuzzes out. Whereas the true people that you want to back can do it. What you find is they’ve spent 5 or 10 or 20 years obsessing over the details of whatever it is they’re about to do. And they’re so deep in the details and they know so much more about it than you ever will.”
