Module 5 · Prototyping

Prototyping Studio

Choose the cheapest experiment that can kill your riskiest assumption, then let Bea stress-test the plan before you build.

You're in preview mode. The method picker, assumption canvas, MVP scope, and success-metric fields all work in your browser. Bea's AI stress-test requires a free account.

1. Pick your prototype method

Every method here can be built in 48 hours or less. Pick the cheapest one that still tests your core assumption.

2. Behavioral hypothesis & metrics canvas

Every field should be so specific that another founder could run your test tomorrow.

Core assumptionWhat specific belief about user behavior are you testing? (e.g. 'Busy parents will pay $19 for a weekly meal-plan PDF')Minimum viable prototype (MVP) scopeAbsolute bare minimum needed to test this assumption TODAY — not next sprint.Success metric (behavioral)Exact user action that proves or disproves your hypothesis — e.g. '5 pre-orders', '10 completed signups', '50% CTA conversion'.

3. Bea's prototype stress-test

Bea will push back on 48h+ scope, opinion-based metrics, and nice-to-have features.
