Churn

In Product Led Growth — The End User Era, churn is the dark mirror of retention — and the metric the book argues most SaaS companies misread. The notes lean on OpenView’s benchmarking: the fastest-growing SaaS companies hit 89% logo retention and 109% net-dollar retention, with the top decile retaining ~20% better than the median. The critical finding is when churn is decided — most of it happens in the first week of use, which makes Onboarding the highest-leverage lever against it.

The book also reframes why customers leave. From their own churn survey: “a lot of our churn isn’t actually due to customers being unhappy, but rather from people successfully completing a project and not knowing what to do next.” The remedy is Jobs to Be Done-based content that inspires customers to do more, rather than feature-based help docs. On measurement, the notes are skeptical of Net Promoter Score as a churn predictor (10 NPS points ≈ 0.9% logo / 0.55% NDR) and argue for tracking actual referrals and product stickiness instead.

Context: Churn rate is the percentage of customers (logo churn) or revenue (dollar churn) lost over a period; in subscription/SaaS businesses it is the key counterweight to acquisition, since a high churn rate forces a company to run faster just to stay in place.

Where this appears

• Product Led Growth — The End User Era — churn as the inverse of retention; most of it decided in the first week (making onboarding the lever), and often driven by users finishing a project, not unhappiness.
