The way to tackle a small opportunity is very different from how to tackle a massive opportunity.
In a late-stage environment, there's only small opportunities.
If you have a thing 1x better than the alternative, you need to have a precise, meticulous, wedge use case that precisely uses the entire gradient with no wastage.
That requires micro-targeting one sub audience and hitting it square on.
If you have a thing 1000x better than the alternative, it can be sloppy, a shotgun approach to a much larger surface.
If you do micro in that world, you'll be very behind, you'll over-target when you could have been good enough for many more people much more cheaply.
