PMF Toolkit

For when you need proof of demand before adding cost.

Time
60-90 minutes with Product + Growth + Finance.
Who
Product lead, Growth lead, Finance partner, and the team owning activation/retention.
Decide now
Choose one gate now: invest, hold, or narrow to one segment.
What it gets you
A go or hold decision backed by retention, not by top-line growth.
What you leave with
30-day PMF action memo with gate, threshold, and next review date.

What to do at each pace

  • • Do now in tighter conditions: Cut acquisition spend until retention is proven in each segment.
  • • Do now in easier conditions: Add channel spend only for segments with repeat usage.
  • • Go ahead when: Proceed when retention on the core action clears your agreed bar for two cohorts in a row.
  • • Pause if: Stop incremental acquisition spend when repeat usage drops below the agreed floor.
  • • Restart when: Reverse from invest back to hold if two consecutive cohorts lose retention quality.

By pace: When conditions say slow down, prove retention first; when they say speed up, push for repeatable growth.

Prep checklist

  • • Bring the latest 2-3 cohorts with activation and retention broken out by segment.
  • • Pull paid vs organic acquisition split so the room can separate demand from spend effects.
  • • Collect 5 recent churn and 5 retained-user interviews for qualitative context.

Run sequence

  1. Collect

    Objective: Ground the discussion in observable behavior from the last 2-3 cohorts.

    Prompts

    • • What percentage of users return in the behavior window that maps to core value?
    • • Which cohort improved naturally versus through one-off interventions?

    Deliverable: One-page PMF evidence sheet with cohort trend highlights.

  2. Stress-test

    Objective: Separate demand quality from channel spend or novelty effects.

    Prompts

    • • If acquisition spend stopped this week, where would active usage settle?
    • • Which segments show repeat behavior without high-touch support?

    Deliverable: Cohort quality score with confidence notes and known blind spots.

  3. Translate

    Objective: Convert evidence into a specific investment gate.

    Prompts

    • • What threshold upgrades this from hold to scale?
    • • What do we stop funding until that threshold is met?

    Deliverable: 30-day PMF action memo: invest, hold, or narrow segment.

Signs it worked

  • • The room leaves with one PMF gate (invest, hold, or narrow) and a date to re-evaluate.
  • • At least one low-quality segment is deprioritized to protect focus.
  • • Next-cycle budget is tied to an explicit retention threshold rather than top-line growth alone.

What's in this toolkit

  • PMF evidence checklist
  • Cohort quality rubric
  • Retention interview template

Common mistakes to avoid

  • • Treating top-line growth as PMF
  • • Scaling channels before cohort quality is stable
