Estonia. Tech country, advanced, lots of startups, in the capital and in tech companies most people speak English, easily understandable tax system, stable political climate, and a good standard of living including public healthcare.

I live there, happy to discuss if there's interest!

Seems like you are not native but moved there. What made you choose Estonia over anywhere else in the world?

Originally, chance. Over a decade ago I was traveling country to country a year at a time, and had never lived somewhere so far north. I booked a ticket and landed with a suitcase knowing nothing about it (no exaggeration, I had no idea.)

Once there I realised it's an amazing place. Lovely people. Peaceful and quiet. Good rule of law and stability combined with kindness (you can trust the police here.) High tech. Beautiful nature. Very clean air. Lots of forest. Big enough to have a big city; small-town living if you want.

It's very business-friendly and I started a company here. Then, married an Estonian, so I guess I'm staying here now :)

I can guarantee that there is at least one country in [geographic] Europe where you do speak the language, and you are likely to find employment. Whether you would want to accept the change in lifestyle and living standards is another question.
