Yes, it may or may not happen. It is more about being in control, being your own boss, being creative. If it pays well - it is a bonus, but not a requirement.
YMMV
For a founder the big pay out can happen in year 6 or year 10 or may never happen..
And there's no guarantee of revenue going up.. ive seen plenty of examples of founders making less money than last year because their business shrank..
maybe because of the market, or competition, or because they got complacent..
Uncertainty is the only certainty in business..
Try at your own risk..
Dont believe everything you see on X
