As mentioned above, there are many similar platforms already that are trying to compete in your chosen field.
Do you have investors or dev funds that can push thru your developments without the need of any crowdsourcing?
Because the usual problem is that most projects are relying on public sale.
And once they can't get their financial targets, the project is either abandoned or with very slow progress of achieving their objectives.
I think apart from crowd funding/ Public sale every project must try to reach investors directly, and try to convince them for investment. There are so many legitimate projects getting not much attention just because investors are afraid of crypto scam. You are right that ICOs must not solely rely on public sale.
