Try to phrase your worth from the perspective of the cost to replace you. Jumping from $90k to $175k is a hard pill for any CEO to swallow. Are you replaceable by some new $120k developer or are you really VPE and they would have to hire a senior manager and a couple coders to fill your shoes? How many people are you managing? Remember, you CEO is going to have to explain your raise, or termination, to the board. What story would be easiest to deliver?
