BTW, obviously all startups handle money in some way, but for these 3 it's a bit more complicated, as they're providing financial services to third-parties. (Ebay+Kickstarter to sellers/buyers, Stripe to sellers.)
You have a small team, often located in the valley or major US city, that expects to spend years working on developing their business model, product and infrastructure. Even if they are fabulously funded all efforts seem to be US centric because there's no way you can split so few people across so many countries when you're still developing the foundations of your business.
Instead of the typical startup organization that all but guarantees that you will expand too slowly to other markets, startups should look into more flexible forms of organization that allows them to set up partnering organizations in other markets. Imagine if your startup from day 0 has co-founders that are solely responsible for offshore markets development, pr and marketing. These co-founders would be an interface between your business and a specific country or region that actively engages with his market so that customers knows what is happening and what your startup's plans are for their market.
What you pay in equity and title you get back in a vibrant presence and a highly skilled and competent person that can guide you through each country's customs, laws and regulations, and bureaucracy.
That said, it is an interesting idea, I know of at least one startup founder that's trying to do just that.
Ultimately it is a question of persuasion, to rally up interest and support for your cause and we've been doing this as long as we've been walking upright.
to address the point more generally, the IFC (private investment arm of the World Bank) does a report ranking the ease of doing business across countries: http://www.doingbusiness.org/rankings
