It really depends. And there are some huge advantages to being a non-technical founder. Two are that a) you are a domain expert, and that expertise is more valuable than technical expertise, and b) you are less susceptible to analysis-paralysis (generalizing I know as that's more a personality trait)

My friend and colleague is non-technical and launched a very successful app. I acted as a virtual CTO and recruiter contract developers. My total hours on the project is <100. While non-technical, my colleague is a professional designer and has domain expertise.
