The Polish legal structure is absolutely inelastic for the formation of a holding company (in terms of intellectual property and patents), so now we are working on transferring all our intellectual property and IP of the entire firm to the jurisdiction that Common Law uses.
Apart from that, the biggest, and perhaps the only problem in Poland is the overwhelming participation of state capital in all investments and, as a result, a terrible bureaucracy, small investment rounds.
While in Ukraine, you can start working on MVP, build a minimal product, and find your first customers. After that, you should move the startup to a quiet, stable jurisdiction where investors will not be afraid to invest money (in Poland, Estonia, Great Britain). The full-fledged development of a startup in Ukraine is still absolutely impossible, there are no conditions for investment. From the banal things – in Ukraine it is extremely difficult to get a regular invoice, elementary international banking operations are also very difficult to conduct, or even impossible, without taking into account the space commission.
The only advantage is legal tax optimization. If part of the staff (engineers, programmers) works on outsourcing in Ukraine in the status of individual entrepreneurs (FOPS). Keeping RnD in Ukraine is quite a profitable strategy. I would like to do something in Ukraine, but in return, I want to have confidence in the future. Unfortunately, the country does not have the appropriate macroeconomic conditions to attract any foreign investment, the role of the national currency in cooperation with foreign clients is very limited, and its instability.
