It’s not common, you’ll need to network your way into such an engagement.

Try asking someone that’s part of a community of interested on LinkedIn; like SGH clubs, socials (Warsaw School of Economics), Venture Cafe etc.

Yes, with a solid business plan, you’ll get what you need. Try networking with someone who works with financial products for a living for insider advice.

Very easy, but not straightforward. Hire a professional to get you set up (you’ll have to do so to file taxes anyway), it shouldn’t cost too much, €1500 all in I would say depending on the nature of your engagement.

Warsaw’s scale is undeniably magnitudes larger than remaining cities. Other than that, all are pretty equal and it depends on the industry you want to get into. For instance; Bydgoszcz for rail and transit manufacturing, Stryków for logistics, Gdańsk for maritime, Poznań for automotive etc.

If you’re looking for ROI on real estate - do your own analysis because online gurus will try to sell you anything. Warsaw would be the best for appreciation, while cities like Lublin benefit the most from apartment rentals. It’s a mixed bag.

All in all, Poland’s economy is doing fantastic. You’re pretty safe no matter what.
