Retention
Summary
The third Distribution phase — keeping customers and compounding their value. Three mechanisms: product stickiness, the customer database, and community. Retention is the most under-instrumented and highest-value part of most businesses.
The three retention mechanisms
1. Product stickiness
The product itself pulls people back — through habit, results, or switching cost. The most durable form of retention because it needs no ongoing spend.
- Course business: curriculum that builds, certifications, updated content.
- Peptide / consumable: re-order cycles, subscriptions.
2. Customer database
The list you own — emails, contacts — grown and worked through email flows. This is the asset that survives platform changes, so it’s a genuine moat.
- Fed by website captures and purchases.
- Worked by lifecycle email (welcome, nurture, win-back).
3. Community
Retention through belonging — a group, server, or membership where customers stay for each other, not just the product.
Why retention deserves more attention than it gets
Retention is where the money compounds
Acquisition gets the glamour, but LTV is set by retention, and LTV is what licenses you to spend on acquisition. The single most valuable instrument to build is a cohort retention curve (what % of each month’s customers are still active N months later). It’s also the most commonly missing one.
Automation notes — and a deliberate limit
| Mechanism | Automation stance |
|---|---|
| Customer database / email flows | High automation (BAU) — lifecycle emails, segmentation, win-back triggers |
| Product stickiness | Mostly product work, not automation |
| Community | Automate logistics, keep humans on relationships |
Don't over-automate community
The original example is exactly right: “updating a user when they come into the community” is BAU (automate the welcome/onboarding logistics). But the relationship work — answering, recognizing, moderating tone — is what makes a community sticky, and automating it away kills the thing you’re retaining people with. Automate the doorman, not the friendship. See Worked examples.
