Churn is the worst reason to have slow growth. Churn means you're not just unknown, or that there's a big threshold to sign up. It means people are actually trying the product and deciding they don't like it.

Insight: When a business has slow growth, there's a temptation to blame the obvious things: not enough marketing, a crowded market, high barriers to entry. But there's something far more damaging hiding underneath—churn, the steady stream of people who try your thing and leave. It's worse because it means you've already won the hard part. Someone gave you a chance. They showed up. And then they left anyway. This matters beyond startups. In any part of life where you're trying to build something—a habit, a relationship, a skill—churn is the silent killer. You can get people interested. You can get them through the door. But if they're not sticking around, you have a fundamental problem with what you're offering, not just how you're promoting it. A gym with bad equipment won't fix its problem by running better ads. A friend group where people don't feel valued won't grow just by throwing more parties. The uncomfortable truth is that churn forces you to look inward. It's a signal that something about your core offering isn't working. Sometimes that's a relief, actually—because unlike being unknown, churn is something you can diagnose and fix if you're willing to listen to what people are really telling you by leaving.
