I worked with plenty of founders like this - they carry a C level title, but never stop being just an engineer or sales guy or designer.
That’s all fine when you have no employees - C titles are bullshit when it’s just two bros in a dorm - but it invariably hurts the company prospects as the team grows.
The common hack is hiring a “VP of Eng” to take care of the actual C-level work.
Mind you, there’s absolutely nothing wrong in wanting to be the guy who sits in a corner and codes. Just don’t call it “leadership” or “chief” anything, since you’re sitting in a role and not acting the part.
