The Retention Metric
If your customers do not renew, you do not have a business. You have a hamster wheel.
Acquisition is Theater. Retention is Reality.
Most founders obsess over filling a Leaky Bucket by spending capital on new leads while their existing cohorts churn out the back. If your model requires constant growth just to stay flat, you don't have a business. You have a Hamster Wheel.
Predictability begins where acquisition stops being the primary focus.
The Leaky Bucket
Most founders focus on filling the bucket (new customers) while ignoring the leak (churn). If you lose 10% of your customers every month, you need 10% new growth just to stay flat. This is a treadmill to nowhere.
The Compounding Machine
When retention is high (95%+), growth compounds. Every new customer stacks on top of the previous cohort. Your revenue becomes predictable. Your valuation multiplies. The path to high retention is not "customer success theater." It is building a product that solves a real problem. If they churn, you built the wrong thing.
