The problem for the mentor is you can succeed and make no "income" but plenty of "capital gains". Or maybe your wife will on paper (nod to sister comment). A mentor would be incentivised to get you working for a high income, a job at Google for example, and not investing or running your own business. The problem for you is someone can come along for 1 hour, mentor you but not do much useful stuff. You then go away and are successful anyway by say using a normal hourly paid mentor, and the original useless mentor want's his 1%. If you are going the business route, pay the mentor per hour, then if appropriate offer them the opportunity to invest in the business once it is ready for it.
