I am going to give you a different feedback. Find something else that pays you what you are worth. If you really want to help this company, find them someone else who would take $30k and when you get your big salary elsewhere invest in it.
Also it is a lot easier to go from Big co to tiny co later in your career than the other way around.

This is likely to hurt you in the long run.
