This is a sign of a startup you should not work at. CEO comp in a startup should be tied to the success of the company in the form of stock. Generally in a tech type startup the salary (cash) of the key developers and the CEO are around the same. The highest comp is on the sales side. The sales team joins late (the founders and CEO should drive sales at the start) and tend to get way less stock. Their comp is based on a base salary and commission which should be uncapped.
