I'm thinking innovative tech that relieves people's pain could be promising.
I'm talking in a literal sense, not the marketing lingo "find the pain!" sense. For example, I stand a lot at work and my feet are throbbing right now from working over the weekend. I would pay good money for an elegantly designed device of some sort that would soothe this pain without me having to really do anything. No matter what walk of life you come from, every single day you will hear someone complain about some kind of pain they're feeling -- e.g. "Ahh, my x is killing me right now!"
