SaaS Metrics That Matter: Activation, Churn, Agentic Margins

SaaS metrics that matter are five numbers - not pageviews, not signups. This episode is the instrumentation guide: the exact Supabase schema for tracking AI costs per user, the Stripe Sigma queries, the PostHog event setup, and the alert thresholds that tell you something is wrong before it becomes a crisis. Covers activation rate, time-to-value, NRR, MRR churn, and agentic margins - with real benchmarks so you know what good actually looks like.
