Can you afford to hire a lawyer to assist you with this, I think your big problem here is that you desperately need a co-founder with a legal background to even pitch this thing.
Getting this to a proper v1 requires a design exercise that's at least 2/3 months long, during which time I need a full-time designer and a full-time lawyer.
I don't think that I absolutely need a lawyer as a co-founder, but I do think that having one would definitely be great. (Which is why I tried that.)
But, sadly, I have neither the energy nor the financial liberty to do so, after the nearly one year of full-time work that it took to get here. (The demo isn't just a mockup; the tech that powers it is production-ready, which is why it took so long; which might've been a mistake, but that's another story.)
