brainstorm-experiments-new designs pretotype experiments and XYZ hypotheses to validate new product demand.
About
The brainstorm-experiments-new skill helps teams validate new product concepts using lean startup pretotypes instead of large builds. It forms XYZ hypotheses in the format at least X percent of Y will do Z, then proposes two or three low-effort experiments such as landing pages, explainer videos, email campaigns, pre-orders, waitlists, or concierge MVPs. Principles follow Alberto Savoia with skin-in-the-game commitment over stated interest and Your Own Data collection instead of relying on market reports alone. Each experiment specifies the hypothesis tested, method, metric, and success threshold. Agents read any supplied research or mockups first, think step by step, and save substantial output as markdown. Use when validating new product ideas, designing pretotypes, or testing market demand before engineering investment.
- Creates XYZ hypotheses: at least X% of Y will do Z.
- Suggests landing pages, videos, email, pre-order, or concierge pretotypes.
- Prioritizes skin-in-the-game signals over opinion surveys.
- Defines method, metric, and success threshold per experiment.
- Encourages Your Own Data experiments instead of third-party market analogies.

How do I test a new product idea cheaply before building the full solution?
Design lean startup pretotype experiments with XYZ hypotheses, skin-in-the-game tests, and low-effort validation like landing pages or pre-orders.
Who is it for?
Founders and PMs validating new concepts with lean startup methods.
Skip if: Optimizing experiments on shipped products with existing user bases.
When should I use this skill?
User wants pretotypes, XYZ hypotheses, or lean validation for a new product.
What you get
XYZ hypothesis plus two or three pretotype experiments with metrics and success thresholds.
- XYZ hypotheses
- pretotype experiment plan
Files
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
1. 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
2. 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
3. Key principles (Alberto Savoia, The Right It):
- Skin-in-the-Game: Test willingness to pay — not just interest. Real commitment (time, money, reputation) is the only reliable signal.
- Your Own Data (YODA): Collect your own data through experiments rather than relying on Others' Data (ODP) like market reports or analogies. "The market for your idea does not care about the market for someone else's idea."
- Measure actual behavior, not users' opinions
4. For each experiment, specify the hypothesis being tested, the method, the metric, and the success threshold.
Think step by step. Save as markdown if substantial.

FAQ
What is an XYZ hypothesis?
At least X% of a defined target market Y will take action Z in your experiment.
Why emphasize skin-in-the-game?
Real commitment through time, money, or reputation beats stated interest alone.
What pretotype types are suggested?
Landing pages, explainer videos, email campaigns, pre-orders, waitlists, or concierge MVPs.
