How much are you willing to tell us about the income source?
I’m finding it difficult to think of anything that generates a small but consistent revenue stream with no babysitting, that is also completely unresponsive to low-effort attempts at scaling it.
Usually if there’s no babysitting, that means low-effort scale. Or if it is hands-free but still can’t scale, it’s because you’ve found the boundaries of the market opportunity (but when is that ever just 1k?)
I guess my question is what niche product/service did you find that the entire world only wants $1000/mo of??
