I'd say yes, but it's harder. It's actually what I plan to do very soon.

He's not exactly an introvert, but one good example is from the founder of my client. He wanted to stay doing the technical work he enjoyed, so he recruited a CEO above him (although he actually still shares a lot of that role and now they nominally share the role), and also hired others the lead the development teams, leaving him to focus on the one specific area of tech that he really enjoys. I'd say his job is about 80% tech and about 40% CEO (and total 120% load because he never seems to sleep!)

I guess the point is to try to fight the urge to do everything yourself. If you're not an extrovert, you'll need to hire a good sales and marketing team to take that side of the business, or you'll end up hating it and/or having no customers no matter how good your product is.

In some industries, older entrepreneurs have a big advantage over younger entrepreneurs, so it kind of depends on what you've been doing and what you're good at.
