The way I am trying to do this now is to only ask for money if I can obtain at least one paying customer who is willing to vouch for me. If I can't market an MVP to at least one small shop, I don't know why a non-fraudulent business partner would want to work with me. In any case, I wouldnt feel great about that relationship.
I've done the burn someone else's fifteen million bucks thing on tech stack shiny rabbit chases. It's really not a fun time in retrospect. Mostly just a sick feeling all the way to the bottom.
