this seems like a very narrow operating space? if i understand correctly.. if you are NOT a DE C-Corp in CA, then everything needs to be reviewed again based on a different structure.
do you plan to offer base templates that better fit companies not following your DE/CA method of incorporation. i would venture to guess most startups don't have the capital nor legal advice to go this route. in fact my CA attorney told me to skip the DE C-Corp in the beginning.
