Why growth keeps costing more and keeping less. Watch the loop close, then look at your own numbers.
A product stops improving fast enough to grow on its own. Retention softens. Repeat purchase slows. Word of mouth fades.
The company compensates the only way its operating model knows how: it buys more customers.
New customers arrive, meet the same product that could not hold the last cohort, and leave at roughly the same rate.
So the company buys more. The trap is self-tightening: every year, growth costs more and keeps less.
The budget that could have made the product better is consumed replacing the customers the product could not hold.
Finance sees rising acquisition costs and flat retention and concludes the market is saturating. Marketing sees the same numbers and asks for more budget to fight the saturation. Both are describing symptoms. The diagnosis is in the questions the room asks.
"Which campaign should we run next?"
"Why do customers who arrive not stay?"
If that is your room, the trap has already closed.
Escaping the trap means the platform starts earning its own growth: learning from every interaction, so every customer marketing acquires lands on a product that gets better at keeping them. That sequence is the Compounding Platform, and it is built bottom-up.
The full argument is the essay. Whether you are in the trap, and which layer is holding you there, is the Score.
