Offer shares publicly without a prospectus? You do realize that is illegal in most jurisdictions? Reading that made me think your somewhat naive, and likely your product would be too. I realize that this sounds harsh, but I'm not saying it to be mean.
Other than that, I assume your product doesn't solve a problem or need enough for people to pay for it. The best idea for next time is to try to establish that earlier.
