Background: I have a web app idea in mind that I have started developing for fun. As I started seeing potential for revenue, I realized that a lot of other competitors have already started this product a few years ago, and have successfully raised funding. These competitors seem to be focused only in one market, when two or three can possibly benefit greatly from it. Most tech-savvy internet users already know this product exists, but average users have no idea that this is available to them. Most average users I have spoken to, mostly strangers, have loved the idea, and wanted to pay to use it already.
EDIT: It would be a low cost service, probably would charge $1 a month, but I legitimately see many millions of users in the other markets. I have spoken to about 30 people, out of which 25 are ready to sign up today for $1/month.
Here is my question: Is my competitors' lack of marketing to this group something I should try and take advantage of? With millions in funding, these competitors are barely startups, but, for whatever reason, have decided not to jump into other markets. Instead of beating them with a far superior product, I am wondering if marketing a similar product to a different niche is worth pursuing? What are the benefits/drawbacks of hitting this full-time?
