Two things from my view:
  1. Try touristy areas as these places will naturally get people around the world to go their good examples of this is Dubrovnik, Split, Montenegro and Athens
  2. Make it stupid simple to get started. Many of these people are not technical at all, they just want to make their products and sell, they don't want a headache. If a 85 year old grandma can't figure it out, its too technical and complicated.
