Validating Product-Market Fit (Phase 2)
Target: $ARGUMENTS
Phase 2 of the GTM pipeline. Depends on Phase 1B. Scores PMF across multiple
dimensions using evidence from prior phases.
Mode Awareness
Read config/mode.md before starting:
concise — Overall PMF score + top 3 evidence points + top 2 risks
detailed — Full per-dimension scoring, evidence matrix, risk register with mitigations
conservative — Weight negative evidence heavily; set high evidence bar
ambitious — Weight leading indicators and analogous market signals; accept proxy evidence
Inputs
results/phase-1b/market-analysis.md — Market sizing and buyer personas
results/phase-0/capability-profile.md — Technical capabilities
results/phase-1a/competitor-map.md — Competitive context
config/validation_criteria.md — Phase 2 quality gates
config/mode.md — Style and approach settings
PMF Scoring Dimensions
Score each dimension 1-10, then compute weighted average:
| Dimension | Weight | Description |
|---|
| Problem severity | 25% | How painful is the problem for buyers? |
| Solution fit | 25% | How well does the product solve it? |
| Market timing | 20% | Is the market ready? |
| Competitive moat | 15% | Can differentiation be sustained? |
| Distribution path | 15% | Is there a clear route to customers? |
Workflow
- Read all Phase 0, 1A, 1B outputs
- Score each dimension with evidence justification
- Compute weighted PMF score (0-10)
- Identify PMF risks — What would invalidate each dimension?
- Propose mitigations for top risks
- Validate against criteria — Check
config/validation_criteria.md Phase 2 gates

# Product-Market Fit Assessment
## PMF Score: [X.X] / 10
## Dimension Scores
| Dimension | Score | Evidence |
|-----------|-------|----------|
| Problem severity | [X]/10 | [evidence] |
| Solution fit | [X]/10 | [evidence] |
| Market timing | [X]/10 | [evidence] |
| Competitive moat | [X]/10 | [evidence] |
| Distribution path | [X]/10 | [evidence] |
## Evidence For PMF
- [evidence point] — Source: [phase output or URL]
## Evidence Against PMF
- [counter-evidence] — Source: [phase output or URL]
## PMF Risk Register
| Risk | Likelihood | Impact | Mitigation |
|------|-----------|--------|------------|
| [risk] | H/M/L | H/M/L | [approach] |
## Recommendation
[Proceed to GTM / Iterate on product / Pivot hypothesis]
Rules
- Both supporting and contradicting evidence are mandatory
- Score deflation is preferable to inflation — honest assessment protects GTM investment
- Mitigation suggestions must be actionable, not generic
