While I agree that salaries can be a pain, especially all the compulsory stuff like health care, social security and so on, for the employer a company that is unable to generate enough revenue or attract enough capital (loans, investment whatever) sounds more like a hobby to me than a viable enterprise. Sooner or later you will have to pay all that anyway, so better get used to it rigzjt of the bat.
Many successful businesses started up as a hobby. The issue with all the compulsory stuff is that you either do your hobby on the "black market" or you have to risk subsidising it.
At least these days some sort of sanity starts to be restored in Poland. New businesses can pay 50% of the minimum rate for first 2 years (if the founder didn't have any other business in last 5 years). And shockingly! there is even talk of possibly allowing people under 30 years of age to make their own decision whether they pay for the pension insurance or not. (Please bear in mind that the money paid for the pension insurance has little relevance to how much you'll actually receive in pension later.)
There is also another thing called non-registered business. Basically anyone can run a non-registered business if the income doesn't exceed approximately $300 per month. Profit is taxed as any other earnings on a personal annual tax return. It is in my opinion a really good thing that allows many hobby-stage businesses to avoid any paperwork whatsoever and still not feel like they operate illegally. Of course good luck trying to find any serious company that will use such a non-registered business as a subcontractor, but if you're in very early stages of starting up it is a very useful construct.
