Start with a gogle sheet, and then leverage that to get to the next step. Find your first customers before you have any code at all. Then build in public. This one is not in the normal place. Tor art a a, build in pubblic. It's like an open angel form for start-up companies. And don't be afraid of being transparent about what you're doing. You'll make more money from it than anyone else who has ever done it.
