Agreed on not joining a startup for the money. Although it seems like a lot of damage has been done in setting a cultural expectation that joining a startup early will see you become a multi-millionaire, to the benefit of startups everywhere I suppose.
Correct me if I'm wrong here, but isn't another major issue faced by early employees that the math might look good when they join the company, but further rounds dilute their stake so much that it becomes meaningless?
