The difficulty with using humans is that it's harder to scale and even then humans can also be wrong.
So we're thinking of how to improve on it. It's a bit mind recking to be honest.lol
One way of scaling it that has already been done is to use the customer's humanness, by selling a book. That scales. Now, if the price point is $500 for a small but high quality business idea validation, what can you do that's better than selling a book on how to do it? Could you train coaches, who then can bill over $100/h and let the customer execute on it? Willing customer right here.
