Is there a reason you're looking for an alternative?

There were 183 founders in the last YC batch. 74 were not born in the United States. That's 40%. They didn't all just come from Canada and UK, they came from 27 different countries. There were actually 17 French founders in this batch, which is the highest concentration we've ever had in a funding cycle.

If your users/customers are in Europe (or elsewhere) and it makes sense, we're not against you learning and raising the money that you need here and taking it back with you to grow.

There's http://www.startupschool.pl/ , something similar to Y Combinator. They're recruiting right now as well (29 hours left). I submitted my application a few weeks ago and got an invitation to the recruitment workshop in early September.
