Which of the following is an example of a validation experiment?

Measuring willingness to pay is an essential validation experiment because it directly assesses potential customers' readiness to purchase a product or service at a certain price point. This type of experiment provides critical insights into how much value customers attribute to a product or service, which helps entrepreneurs adjust pricing strategies and refine their value propositions accordingly. Understanding willingness to pay allows startups to gauge market demand more accurately and ensures that they position their offerings effectively to attract the right customer base.

In contrast, creating a product demo, while useful for showcasing features, does not specifically validate whether customers will actually purchase the product. Surveys can provide valuable feedback but often fail to capture actionable insights regarding actual purchasing behavior or willingness to pay. Testing marketing channels is also important for understanding where to reach potential clients effectively, but it does not directly address how much customers would be willing to pay for the product.
