Creating custom hardware (instead of white label) is even harder and requires a significant amount of cash up front.
The main alternative to private funding is crowdsourcing, and I can say from personal experience that there are many problems with that approach as well.
I don't have a good solution, but I do have empathy for people who are trying to find one.
