IPO's are not public in the sense that they make public who gets what (except at the top levels), they are an initial public offering of stock. How many % is allocated to employees is a very complicated process depending on how much dilution happens and if any down-rounds have happened, or funding needed to be done in a rush (look at say Box ...)
