This sounds fascinating to me. I'm looking at doing the same thing - launch a product for global audience while relocating back to India.
Any idea how long your friend took to gain traction?
What do they do to find a community of fellow techies/dropshippers/SEO mavens/whatever in Greece?
Do they ever talk about moving back to north Europe?
I don't keep in that close contact, but as I understand it he hasn't precisely moved back to Greece. The business is incorporated in northern Europe and he has his legal residence there. It's just that since there's no office to go into there's no real need to be physically present most of the time, so nothing stopping him from doing much of the work remotely from Greece. It probably does help that Europe is fairly small and flying back and forth is not too difficult.
