You can never solve a problem with the same thinking that created it.

That quote hits home when a lot is at stake and you have already run through every scenario in your head.

Maybe you don't need more information. Maybe you need someone to look at your plans from the outside, spot the contradictions and ask the question you can no longer see yourself.

We often only look for help once something has already become a problem. With a US project, it's better to see the weak spots before you sign, incorporate, invest or move.

Especially with US tax, companies, visas and legal questions, one wrong assumption can get expensive later.

What do you gain from talking to a US expert?

You've probably done your research already, read the articles and run the numbers on different models. Now you want to know whether your conclusions hold up, without hiring a firm for a large engagement right away. That is exactly what this consultation is for: one specific case, your questions and a clear outside view.

That's exactly what this session is for.

You book a single consultation hour and discuss your plans directly with an experienced advisor.

Bring your preparation, numbers, ideas and open questions. Our goal is that after the call you see more clearly what works, what's missing and where you should rethink.

If we don't share your view, or think part of your plan is unrealistic, we'll tell you openly.

In our consultations we see a wide range of business models, family situations and ideas. That experience helps us spot faster where an approach works, where it clashes and which question hasn't been asked yet.
