THE HIDDEN MATH OF CHURN: WHY YOU CAN'T SCALE PAST $1M

Summary from the TLDR Marketing newsletter

Subscription businesses often fail to scale because they prioritize growth over retention, not realizing that churn mathematically caps their total user base and revenue potential. At a 20% monthly churn rate, a company will lose 100% of its users within a year, making sustainable scaling impossible without continuous and expensive customer acquisition. Companies that optimize retention benefit from extended growth cycles, greater valuation multiples, and increased profitability, while those that ignore churn struggle to maintain a growth trajectory.
