research process - Will a PhD help me as a startup founder?

I'm planning to get double honours in CS and Pure Math. (Link to my previous post.) But I'm very confused about getting a PhD. Will it help me as a startup founder?

The only thing that is stopping me from getting a PhD is time. I have excellent grades(almost perfect GPA). I'm very motivated to launch startup after graduating(maybe after working for a year or so). The only thing that's worrying me is that if I get stuck on a problem while working at my startup and the problem involves some sort of research, Will I be able to do research and solve that problem with my background(CS and Pure Math)? Say that problem is related to machine learning and involves creating a more intelligent machine.
