The fact that they plan to keep things running indefinitely if possible seem to indicate that servers and bandwidth are not the bulk of the cost

So I guess most of it is on paying developers and maybe some office space. 25,000 won't go a long way, even taking in to account cheaper salaries in Greece.

Edit: Their team page says they have 6 employees, so 25,000 probably doesn't go a long way.
