How much am I worth to my business is an archives tag for lorenweisman.com and the title of an article of the same name discussing self pricing approaches.
On a closely related question, in raising capital for the business, can I justify an investor paying me the amount I think I am worth.
With many entrepreneurs believing they should be paid top dollar right out of the gate, they end up turning away a lot of top prospects because they put too much in for the allocation to be paid. Even when you get an investor, you might still have to work another job till you can truly justify that every hour needs to be spent on this given project. It would be nice to quit everything else, drop everything else and do nothing but your dream, but take the view of another.
Are you really ready and while you will most likely be worth a great deal more to your business than what you will be paid at first, it is better, more humble and the professional thing to do to take the lowest amount possible to get the business to the profit point where you can then look to make what you are worth.
