Have You Incorporated in Estonia?

I have one company there. I'm planning a migration to a different arrangement, but depending on what you are trying to do it might be OK.

If you want to be incorporated in the EU and are from an EU country where the government UX sucks, it might be worth it.

If you are a B2B software company that frequently hires contractors in the EU it's better to have the company outside the EU as there's less paperwork involved. Also tax reasons.

I haven't and have yet to see any advantages to do so.
