A lot depends on the field of activity, for example for IT business or high-tech projects it is easier to find public or private financing than for young law firms.
Today, there are quite a few options to get funding for a startup:
grant funds from private and state foundations, such as the Ukrainian Startup Fund, the Ukrainian Cultural Fund, and other foundations.
There are programs of subsidies and assistance to certain types of businesses, mainly in the agricultural sector.
Loan programs, e.g. 5-7-9.
However, it is better not to rely only on state support and diversify funding sources.
