Key Concepts

Metric Categories

Metrics are organized into four families:

  1. Revenue & Growth — Top-line money (revenue, ARPU, ARPA, MRR/ARR, churn, NRR, expansion)
  2. Unit Economics — Customer-level profitability (CAC, LTV, payback, margins)
  3. Capital Efficiency — Cash management (burn rate, runway, OpEx, net income)
  4. Efficiency Ratios — Growth vs. profitability balance (Rule of 40, magic number)
