Possible sure - just as it is possible my next startup could be the next Tesla. In reality, when Elon joined Tesla they had nothing but early concept prototypes of a high-end sports car with the name Roadster. Elon took it from concept, to launch, to production. Then he did the same with the Model S/X/3, sold 5 million electric vehicles, made them so compelling that it completely disrupted the ICE vehicle market and sparked a gold rush of elecrification in the car industry resulting in a Trillion-dollar company. It's possible "which Musk didn't found" is doing some heavy lifting in your statement above.
