Ask HN: What is the chance of single non programmer founder getting funded?

My friend who is not a programmer is thinking of starting his own startup. He is a single founder as his friends are not willing to take the risk of going full time due to the current economy situation. He is determined to do it, so he would outsource his project.

I told him that the chance of getting accepted in an incubator program may be close to zero, not that I discourage him, but I am just reading from Y Combinator FAQ (even a single programmer founder is having a hard time getting accepted at Y Combinator). He told me that to prove that his idea can work, he will have the prototype made.

Assuming he gets to that point and able to demo it, what would be his chance of getting accepted at some incubator programs like Tech Stars, Y Combinator, etc?

What about his chance of actually getting some funding (hundred of thousands USD) and actually can go full time and hire 1-2 technical people to improve and implement new features?

I appreciate your inputs.

Thanks.
