I knew a guy who was a sales executive. He managed to bluff is way into getting hired as CTO, even though he was not technical. Figured he could just bone up on stuff as he went along. I checked in on him maybe 6-9 months later. CTO no longer mentioned anywhere on his LinkedIn. A CTO shouldn't necessarily be super technical, but they should understand technology in ways that maybe a regional sales director wouldn't. And don't get me wrong, he was a smart guy in his own way, but just not as smart as he was dead sure that he was.
