If these "masterminds" actually offered effective advice, then the best way for them to make money is find likely candidates, PAY THEM to take the advice, and then GET PAID a share of the success.
Sounds ridiculous? It isn't. A wide variety of businesses do some variation on exactly that. For example this is exactly what Y Combinator does. It is how coding camps work. You can find interview coaching that works on the same principle - they get a share of your first year's salary.
But if THEY ask YOU to pay THEM, maybe the advice is worthwhile and maybe not. However their business model should not inspire you with confidence.
