I’d worry about talent pool being too small (Estonia has a population of only over a million people). It might not be easy to get people from outside to relocate there, as no one else in EU (expect apparently some Finnish people) speaks Estonian, the weather is grim and wages aren’t that enticing. That’s probably why the government is trying very hard to attract foreign startup investors, as otherwise Tallin is at a disadvantage vs say Warsaw.
Yes but Estonia has https://ccdcoe.org/ as well as numerous IT companies and startups already (most famously, Skype, now a Microsoft office). Plus I don't think you would have any issues having an English-speaking software development office.
Honestly Poland's far-right is a big turn off for me and if I were an ethnically Indian/Pakistani/Turkish software engineer I wouldn't want to live there. It also just doesn't seem like as nice of a place to live. Admittedly, I haven't done much research in terms of what I would need to do as a non-EU resident to get temporary residence there though. I would love for my notions to be proven wrong.
I’ve worked with a number of Indian and Arab people in Poland. I’ve never heard them complain, and some have settled here for good. I am sure there is some level of latent racism here, but that’s true of any society.
Regarding tech companies, Poland has Google, Amazon and some pretty good game studios (CDPRed). It is not an innovation hub by any means though and most people just do regular corporate programming (frontend, backend) or maybe some not terribly innovative startups. If you want to create something based on existing tech, Poland will be fine, but if you want to develop new one, you might have trouble finding the people for it (that’s true for 99.9% places in the world though, Tallin included most likely).
As for Poland being a nice place to live - just come to Wroclaw or Krakow for a weekend when you have a chance and see for yourself. IMO there’s very little difference in living in Warsaw vs say London or New York. The air quality is a worse in the winter - on the other hand, there are no drugs/drug dealers on the streets, no homeless people (or very few), no guns/murders and no terrorism.
Regarding the temp visa, sadly I don’t know anything about it.
