Question
Without having to wait for public tenders because those are only few times per year. Instead, I'm looking for some form of non-payback grants, corporate purpose donations, etc. Does anyone from you have such expertise so we could discuss a bit further? I already considered KickStarter and IndieGoGo but it's near impossible to get anything there and on top of that, people there want a share of revenue if and when earned.
Answer
I would recommend looking for funding by due contribution. Depending on which country you are in, there is partial financing or funding that does not have to be repaid. To do this, you need to be educated, and your idea (idea stage) should be well-developed. Your pitch slides should also contain all the relevant information. There is also certain early-stage and pre-seed financing from government agencies that includes favorable interest rates. In order to give you more information, further details are necessary. Foundations and trusts also have startup funding as part of their objectives. You can also check here and submit applications.
