Yeah, I'm spinning up a startup that will require about $2M in yearly sales in order for us to make a decent living off it. But, it's a marketplace app where we take a commission on each sale, so our margins are very low compared to (hopefully) what the actual sellers are making.
It's untapped, I like the subject matter, and it will be genuinely useful to the people involved. I'd rather be poor doing what I love rather than rich working on something I hate (or am indifferent to).
