Yes, I've seen a number of ways in other companies. Brian's salary as CEO might be $1 but he might have other roles where he's paying himself out of company funds. Consulting is a popular one.
Also Brian said he didn't sell a share. Was he talking about not selling series B shares as the flow of his grammar would indicate?? He didn't say he didn't convert and sell common. Maybe he's just bad at grammar.
Either way I agree with you. Money which investors invested into Humbl is finding its way into Brian's bank account in some way.
