PMF Toolkit
Decide now: Choose one gate now: invest, hold, or narrow to one segment.
When to use: Use this when you need demand proof before adding cost or complexity.
Operating outcome: A go/hold decision backed by retention quality, not just topline excitement.
Typical runtime: 60-90 minutes with Product + Growth + Finance.
Artifact you leave with: 30-day PMF action memo with gate, threshold, and next review date.
Bounded operating rules
- • Do now in tighter conditions: In Safety Mode, tighten spend until retention quality is proven by segment.
- • Do now in easier conditions: In Risk-On, loosen channel expansion only for segments with repeat usage.
- • Proceed threshold: Proceed when core-value retention crosses your agreed PMF threshold for two cohorts.
- • Pause if: Stop incremental acquisition spend when repeat usage drops below the agreed floor.
- • Re-open when: Reverse from invest back to hold if two consecutive cohorts lose retention quality.
Posture split: In Safety Mode, focus on retention proof; in Risk-On, push for repeatable growth.
Who should run it: Product lead, Growth lead, Finance partner, and the team owning activation/retention.
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
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.
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.
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.
Success signals
- • Leadership exits with one PMF gate (invest / hold / 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.
Included instruments
Common mistakes to avoid
- • Treating top-line growth as PMF
- • Scaling channels before cohort quality is stable
