I agree 50/50 split is best, I agree with most of this [1] article (recently posted on HN) about founder equity.
I also agree that choosing non-profit will most likely help our cause, it would take the company in a different direction. This is something we'd prefer to discuss with smarter folks (hence the desire to delay some of these decisions).
I'll keep dissenting: 50/50 is usually not the right solution. Please google founder equity calculator, and use it to start a conversation about who does what and who is committed.
For the YC application, just say that you are not incorporated yet and that you are thinking of splitting 50/50, that should be good enough for them to review.
