    Estimated time: 8-10 hours
    Semester 1/Phase 1 · Think Like an AI Founder/Week 4

    Lesson

    This week turns customer evidence into a testable offer. You will publish a simple landing page and measure whether the right people take a meaningful next step.

    What you will be able to do
    • Define a narrow customer and a clear promise
    • Choose a credible offer and price hypothesis
    • Write landing page copy in the language of the customer
    • Collect signups or preorders ethically

    A clear offer

    An offer combines a specific customer, an important problem, a useful outcome, a way of delivering it, and a price or next step. Narrow offers are easier to understand and test. Avoid broad claims such as helping everyone work better.

    Copy that earns attention

    Lead with the customer and the change they want. Explain the problem in familiar language, show how the offer works, reduce obvious risk, and ask for one action. Claims should be specific and supportable. Do not invent testimonials, customers, or results.

    A landing page is an experiment

    The first page is not a final website. It tests whether the message attracts the intended audience. Choose one primary action such as joining a waitlist, booking a call, or placing a refundable preorder. Track visits and completions so you can calculate conversion.

    Interpret the signal

    A signup is stronger than a compliment, and a payment is stronger than a signup. Low conversion can mean the problem, audience, message, offer, or traffic source is wrong. Change one important variable at a time so you can learn from the result.

    Video of the week

    Why it fits: Provides a strong framework for defining the customer, problem, urgency, differentiation and value proposition behind an offer.

    Recommended sections: “Who,” “Minimum Viable Segment,” “4U framework” and “Gain/Pain ratio.”

    Video activity

    Convert the value proposition into a landing-page headline, three benefits and one call to action.

    The video supports the lesson above — it doesn't replace it.

    Guided activities

    1. 1Write three versions of your promise and test them with peers
    2. 2Sketch the page on paper before opening a builder
    3. 3Ask five target users to explain the page back to you after a five second view
    Prompt you can adapt
    Help me draft a validation landing page for this customer and problem. Use this structure: headline, short explanation, three concrete benefits, how it works, trust section, frequently asked questions, and one call to action. Use plain language from my interview notes. Flag any claim that is not supported by evidence.

    Week 4 · Case study

    VibeMastery’s waitlist reveals the wrong audience

    Source note: Documented founder account. The audience mismatch and decision to stop come from the founder’s own project write-up. The student-sized version below is an illustrative exercise, not part of the reported case.

    In early 2026, solo founder Luis Güette created VibeMastery, a course intended to help non-coders understand and maintain AI-built applications. He built a polished landing page and opened a waitlist.

    The page attracted interest, but every lead was already a working developer—the opposite of the intended audience. Rather than spending months building the complete course, Güette treated the audience mismatch as evidence and stopped the project.

    This is a valuable validation result. A landing page is not successful merely because people submit their email addresses. The right people must respond to the right promise.

    Student-sized version

    Create a one-page offer with one audience, one problem, one promised outcome, and one call to action. Show it to 20 relevant people and record who responds and why.

    Discussion question

    What should the founder have changed first: the audience, message, distribution channel, or product?

    Assignment

    Launch a live landing page and work toward 25 waitlist signups. Submit the page link, audience and offer statement, traffic sources, visit and conversion numbers, and three lessons. If you do not reach 25 signups, explain what you tested and what you will change.
