“you've got to compound subscribed users you just have to make that compound over time that means you have to retain those subscriptions so if you're doing a one-year subscription your most important metric is year two renewals right if you're doing a three month subscription your most important metric is month four renewals”

Compound Subscriptions by Maximising Renewal Rate at the End of the First Period

Subscription apps grow like compound interest: the core metric is not trial conversion or even first-period revenue, it is renewal at the end of the first paid period (year 2 for annual, month 4 for quarterly). Everything — pricing, content freshness, social features, onboarding depth — should be evaluated against its impact on that single renewal moment. Getting that right compounds over years.
