That's an interesting point, but I think having a Founder's or Entrepreneurial mindset is the key to success here and not the founder's professional discipline.

That's an interesting point, but I think having a Founder's or Entrepreneurial mindset is the key to success here and not the founder's professional discipline. It's about the combination of ideas, execution, and money. No single profession owns that. Lots of successful businesses have been founded and run by founders with no formal engineering training. They all need some level of business knowledge, but that can to some degree be learnt on the job.
