If you say inventors, some times inventors do not usually have the capital to set the business behind their invention. So this will require investors to do that leaving the inventor with little leverage over their invention.
However some inventors/innovators like Elon musk, Steve Jobs, Mark etc are entrepreneurs giving them an upper hand in their invention /innovation where by they require little or no investors.
It makes sense for entrepreneurs to allows or accept investors for win win or for shared losses as the case may be..
On a large scale an entrepreneurs will need investors and or inventors /innovators in one way or the others
With the statistics at hand (global) it shows ordinarily that entrepreneurs profits more than the others (inventors/innovators, and investors).
Example is aliko dangote the then richest black person for years who is basically an entrepreneur and has investments but not an inventor but has inventors/innovators..
However, it's always a combination of two or all of (entrepreneurship, invention/innovation or investment)
