I'm not sure exactly what you mean by 'born' but insofar as people are 'born hackers' people are also born idea people. The special ones are people who are both.
People are born creative, sure, but not necessarily as someone who simply applies their creativity to startups / startup ideas. Both idea and product development can be learned over time thankfully. Just one year ago I was a business guy, and I knew no code. Now I'm learning machine learning, have built several web applications, LOVE the unix shell, etc. All in under a year.
