Honestly, even if I knew of a bunch of potential markets I'm not sure I would won't you to know. Your motivation isn't that you care about a particular market or problem. It seems your just looking for the most efficient way to 10x your profit. Dispite knowing much about the people/ product/ market you may serve.

I've lost count of the things that I have used in the past that I have stopped using because the product sucks now and is of lower quality or they have blessed me with a subscription model that only cost $5 or $10 a month. Instead of sucking it up and paying for something once I have to die by a thousand cuts and pay for something the rest of my life if I want to use it. Sure it's great for the profits of that company but not for me.

So maybe that's the underserved market. A product that respects privacy and leaves you the heck alone.
