I've never fully committed and built a solo product, so take what I say with a large pinch of salt, but from what I understand asking your friends "would you buy this" is supposedly a notoriously poor metric for market fit. Their answer is always going to be "of course!" because it's easy and it seems supportive, but the difference between "would I spend this hypothetical money on this hypothetical product" Vs spending real money is huge.
