DeepMind was also founded in the UK and later bought by Google. Their HQ remains in London.

DeepL, who are providing a much better translation product than Google or Microsoft by many accounts, are a German company.

Spotify, which I'm sure needs no explanation, is a Swedish company.

While it is certainly true that the US pays better, I think you need to re-evaluate your position that noone else is creating good or valuable products.
