The AARRR model, growth vs marketing, picking a north-star metric.
Funnels leak. Loops compound. Modern growth thinking shifts from funnel optimization to loop design.
One metric that captures the core value your product delivers. Everything aligns to it.
Retention is the most important metric. Without it, acquisition just fills a leaking bucket.
Growth marketing is systematic improvement of acquisition, activation, retention, revenue, referral across the full customer lifecycle.
