I wouldn't start with funding. If you haven't already started, I would begin by creating a basic function MVP product and introduce it to 35-50 or so potential buyers and get initial validation. They might give you the necessary feedback to improve and focus or pivot into a winner. By keeping them in the conversation you can draw them into funding the new business. That's how Quibb - and so many others - got started. If you already have your business up and running, I'd consider bringing in a respected industry co-founder (and ask that person to fund), or ask friends/family to help out with a reasonable rate loan.
