I think the reality is Startups are hard enough as-is and non-technical solo founders are doing something already difficult with one hand tied behind their back. The successful ones I’ve seen almost always operate in a domain where they’re subject-matter experts so while they’re not technical they have a deep understanding of the problem and can communicate it clearly to a developer.

It’s also more difficult these days to be a non-technical founder because hiring technical staff is still challenging despite all the layoffs. I’ve seen them make some really bad hires.
