You can’t really unless you have done it before in which case you would not be asking here as you would already have the network that would give you the money. There are a few ways you could manage this. 1. Find a single rich individual who will back you. This is not going to be easy, but it is possible. 2. Raise less and move the development team to a low cost country. A tight team of a half a dozen smart people can get a lot done if they have time on their side. 3. Work on something else first, sell, and try when you have money and credibility.
