Sounds like you’re getting wayyy ahead of yourself and asking the wrong questions on multiple levels. (Yet another case of the naive technical cofounder.) A better question might be whether your cofounders consider you to be a founder if you are getting less than 10%.

Agree, have you gotten into YC? Do you have legal agreements? Does the title matter?

I'd pick up a copy of the book Founder Dilemmas
