Brainstorm Experiments New

This generates XYZ hypotheses and pretotype experiments for validating new product ideas using lean startup principles. It walks you through creating hypotheses in the "At least X% of Y will do Z" format, then suggests 2-3 low-effort validation methods like landing pages, explainer videos, or pre-order campaigns. The approach is grounded in Alberto Savoia's pretotyping methodology, emphasizing skin-in-the-game commitment over stated interest and your own data over market reports. Use it when you need to test market demand before building anything substantial. It's practical for startups or product teams wanting structured experiment design rather than just building and hoping.

Design Lean Startup Experiments (New Product)

Create XYZ hypotheses and design pretotype experiments to validate a new product concept with minimal effort.

Context

You are helping validate a new product concept: $ARGUMENTS using lean startup methodology.

If the user provides files (market research, landing page mockups), read them first.

Instructions

Create an XYZ Hypothesis in the form: "At least X% of Y will do Z"
- X%: The percentage of the target market expected to engage
- Y: The specific target market (e.g., "mid-size luxury sedan buyers")
- Z: How they will engage with the product
Suggest 2-3 pretotype experiments to test the hypothesis with minimal effort. Consider:
- Landing Page: Test interest by measuring sign-ups or clicks
- Explainer Video: Test understanding and appeal through engagement metrics
- Email Campaign: Test demand through response and click-through rates
- Pre-Order / Waitlist: Test willingness to pay through skin-in-the-game commitment
- Concierge / Manual MVP: Deliver the service manually to test value
