Ask HN: Whose problems would you like to solve, and why?

I've been doing a rethink on how to approach a product, and it came down to this question. When I go through my personal network, I either don't know or adequately understand the real problems of the people I like, and in the security field, it's very easy to fall into the trap of pursuing the counterfactual case of, "if only people would just do xyz..." So outside my field, it would be really helpful to read about, as creators, who specifically do you really want to help? More accurately, who would you be really happy to bring some relief to, empower, or get an "I love this product!" e-mail from, and what is it about them that makes it important to you?
