Why Growth Runs You Out of Cash
Every new customer costs money today and repays it over months. Grow fast enough with that gap open and you go broke while the spreadsheet insists you are winning.
Acquisition is paid up front and in full. Delivery is usually paid up front too. Revenue arrives in pieces, over time. The faster you grow, the wider that hole gets before it closes.
This is the death spiral: cash gets tight, so you cut advertising, so fewer customers arrive, so cash gets tighter. The business strangles itself while its profit margin still looks healthy.
Profit is an accounting opinion about a period. Cash is a fact about a Tuesday. Money models are built around the second one.
Find the hole before it finds you
Chart cash, not profit, by week
Plot money actually in the account week by week for the last quarter, then overlay the weeks you spent most on acquisition. The dip is your exposure.
- Which weeks did cash actually dip?
- What was I spending then?
Ask what doubling ad spend would do
Run the same cohort math at twice the volume. If cash goes negative, you do not have a growth problem — you have a money model problem.
Fix the timing before the ambition
Pull revenue forward with a faster-paying offer rather than slowing growth down. Slowing down is the expensive fix.
Businesses rarely die of thin margins. They die on the Tuesday payroll clears and the money is not there.
