Well my day job deteriorated to a state where the stress of staying on far exceeded the anxiety of leaving it, so the only rational thing to do is to cut it off. As for customer development, there are already multiple healthily-growing startups doing what I'm doing; there is a market, no doubt. It's a matter of reaching them now. It's an MVP, not a full-fledged product. Worst comes to worse, I'll do a major pivot or shelve it.
