It's ironic how "what everyone says" is often still the right advice. Maybe this is one of the things you need to learn from experience, no matter how smart you are and how many blogs of smart people you read. I am thinking maybe the reason that there is so much more competition in these markets you listed, for a big part is that they are much more addressable. We "technology people" almost have a reflex "I have a problem, I am going to google the solution.". That reflex might be much less developed with spa owners and other small business owners. They might be more inclined to ask a fellow business owner, how they handle problem instead. Maybe you would need to run ads in spa-owner-magazines (I don't know if that exists) to reach them or something like that. EDIT: I don't know if you agree, but maybe another lesson is: just because a market is big (US), that does not mean it's the best business opportunity. Maybe you should have started this in France first and then scaled to other countries when and if you had a working business model. [I am just thinking out loud, I think if I would have worked on the same idea, it would have turned out much worse.]
