CEOs dread “exponential” headlines—stocks, viruses, hype. But unchecked spikes crash; logistic curves explain why WhatsApp user growth flattened once almost everyone had it.
Key Differences
Exponential: J-curve, unlimited resources. Logistic: S-curve, carrying capacity. One predicts boom-and-bust; the other predicts steady saturation.
Which One Should You Choose?
Forecasting pandemics? Use logistic. Projecting compound interest? Use exponential—just remember reality eventually applies brakes.
