How failure shifts by stage

A moving target.

What threatens a startup is not what threatens a $10M business. Every plateau demands a different operating model.

Stage	Revenue	Primary failure drivers
Startup	$0–$500K	No market need, ran out of cash, wrong product
Growth	$500K–$3M	Founder burnout, premature scaling, wrong hires
Scale	$3M–$10M	Margin erosion, process gaps, leadership bottleneck
Maturity	$10M+	Silo drag, failure to innovate, capital misalignment
