Free validation planning tool
Product Validation Experiment Planner
Turn “I should validate this” into a concrete test. Choose the riskiest pillar, your current evidence, buyer access, price level, and time window; the planner builds a focused experiment with pass signals and anti-signals.
Next step
Run the smallest test that can change your decision.
If a test cannot make you continue, change, narrow, pause, or stop, it is probably activity—not validation.
