Ask HN: US presence needed?

I'm planning to start a SaaS startup and I want it to be located in US (more business friendly that my country, access to stripe.com, easier from a marketing pov...) while staying in my country (with regular business travels to US). But to do so, I'll need an American co-founder for the non-technical side (from paperwork to social marketing and much more).

Do you think it's doomed to failure because of the non physical proximity between the founders ? If not, how to find such a partner ?
