We have considered spending some time in Thailand, but we are concerned that the fixed costs of moving (plane tickets, visa, etc.) would outstrip the month-to-month savings unless we chose to stay there for over a year.

While our project estimate could be wrong, we intend to spend much less than a year working on our prototype before we can raise.

Our potential customers are almost all in SF, NY, LA, DC, and Boston. If we stayed in America, we would not be living in any of those cities, but could travel to some of them by car.
