Measure, Keep, and Grow

Start here — Becoming a product-led growth team

What product-led growth actually means, why it's an operating model any startup can adopt, the evidence it works, the five ways teams get it wrong, and the map of the system the rest of this course builds — in nine short pieces.

In this chapter: what product-led growth means in practice, why it's a way of operating rather than a tactic you bolt on, how it applies to any startup (not just self-serve SaaS), what the evidence says, the five ways teams get it wrong, and the map of the machine the rest of this course builds. No setup yet — this is the mindset the tools serve.

How this chapter works. It's nine short pieces — most a one- to three-minute read, two with a talk worth watching (read the digest and transcript if you'd rather read). Work through them in order, or jump to what you need:

  1. The shift this course is about — growth as a system your team builds, not a thing marketing does.
  2. What "product-led growth" means — the strict definition, and the go-to-market motions around it.
  3. Product-led as an operating model — the universal part, whatever your startup is.
  4. Growth is an engineering discipline — hypotheses, not tactics.
  5. Who owns growth on a small team — assign the hat, make the ritual cheap.
  6. The machine you're going to build — three layers, one loop, on one page.
  7. How teams get this wrong — the five failure modes.
  8. The one rule: measure → keep → grow — the order that never reverses.
  9. Before you move on — three things to settle, then check yourself.

Words you'll meet in this chapter.

  • North Star — the single metric that best proxies the value your product delivers; the number the whole team steers by.
  • AARRR — Acquisition, Activation, Retention, Referral, Revenue: the five stages of the growth funnel (the "pirate metrics").
  • CAC / blended CAC — customer-acquisition cost, what it takes to win one customer; blended CAC averages that across every channel, paid and organic.
  • Holdout — a slice of users deliberately left un-messaged, so you can prove a journey caused the lift rather than assuming it.
  • Incrementality — the extra outcome an action actually caused, above what would have happened anyway.
  • Identity graph — the record that ties one person's many identifiers (email, device, Discord) to a single profile, so you never pay to reach them twice.
  • ARR — annual recurring revenue: the yearly run-rate of a subscription business.
  • Dunning — the sequence that recovers failed subscription payments (expired cards, retries) before they become churn.
