This is the most awkward thing you could say.
Like, what value does an SRE engineer bring? Or a cyber person? For a large company; basically nothing on average, until you save them from a major incident, then potentially loads.
I would never use this sort of phrasing, that sound really painful. Have you ever actually used that in a negotiation?
Rather I'd highlight my experience in achieving results at reduced cost, identifying efficiencies, and developing new sources of revenue to highlight my own ability to bring extra value. You're the one asking for more, so you need to justify it.
I'd like to hear more about how it went for you. It seems like one of the ultra logical views which people find weird (or offensive) when spoken out loud. I mean, the principle here is clearly true, both the employee and employer must profit, if this condition doesn't exist the company soon dies.
Or maybe the more open ended question is better?
I do like Never Split the Difference, great book. The most common complaint against it is that the author is a bit arrogant, but having read a couple other negotiation books first, I found the author's approach more fair and "real" than the bag-of-manipulative-tricks I found in the other books.
Also, since it's the CTO your talking to, try to establish an (for lack of a better term) "tech people versus the rest of the world" mentality, then he will be more likely to side with you. As we've all seen, people side with their own perceived group. I don't mean this to be as aggressive as it sounds, just try to use the natural camaraderie between tech workers.
