As far as I know, there are no EMIs in Poland that offer these types of services (there's only one and it doesn't seem to offer accounts) and not being a Eurozone country (plus local banks being pretty good at technology/product), there probably isn't much demand or market opportunity.
Some Polish banks have historically been quite easy to open personal accounts with even remotely: Alior, mBank, Pekao, Bank Millennium, but I don't know if that's still the case. Company accounts used to always require a personal visit and regulations have tightened since, but if you can prove local economic activity it might be enough to satisfy them.
