What growth metrics should I actually track as an early-stage startup?

The short answer

Track one North Star metric that captures real customer value (weekly active users, orders shipped, revenue retained) plus the inputs that move it. Ignore vanity numbers like total signups or app downloads; measure the point where users get value and how many come back. Fewer metrics, checked weekly, beat a 40-line dashboard nobody reads.

From Reforge Blog by Brian Balfour & Reforge team ~15 min read

  • Funnels are one-directional and decay; loops feed their own output back into new-user input.
  • Every retained user should generate the next user through content, referral, or reinvested revenue.
  • Designing loops forces you to think about defensibility and compounding, not one-off campaigns.
