Ask HN: Americans creating European startup – where to incorporate?

We're a group of primarily Americans developing an app in the US, aiming to launch in the Netherlands. Despite making lots of progress on our product, we've yet to create an actual company. We're bootstrapping it as far as possible and would like to keep costs minimal.

If we want to launch in the Netherlands, would we be at a disadvantage being incorporated in the US?

How would the decision affect us in terms of: Taxes? Equity or Debt Funding? Ease of business in Europe?

Thanks in advance!
