I worked for a "start-up" in 1994. I was employee number 600. And it had just gone public. The firm eventually had something in the range of 30,000 employees.
Anyway, at that point in 1994, the first 30-50 employees all made $$$. That included the secretaries and receptionists. They were all millionaires.
Something has changed and that is the terms that VCs and Executives have negotiated for themselves. I have not heard of any secretaries getting $$$ in a long time. There is a lot less sharing in the spoils than there used to be.
