Is there a way to check if a product will sell before creating it?
You could create the product first and then gauge market response, if demand is lower than expected, you could end up with high production costs and a large inventory burden. That’s why many brands go through a market validation process to gauge market response before launching! In this article, we’ll compare common market validation methods—such as MVP, in-depth customer interviews, social media testing, surveys, and funding—and introduce ways to gauge demand through actual purchases, along with success stories.
1. Why Market Validation Is Necessary Before Product Launch
When preparing a product, the first concern that comes to mind is, “Will this product actually sell?” This is because, even with a great idea, it’s difficult to know whether it will lead to actual customer purchases until after launch! That’s why many brands conduct market validation before launching to assess actual customer reactions and purchase intent, thereby reducing startup risks.
2. Comparison of 5 Methods for Pre-Launch Market Validation
There are five main methods of market validation. The level of market response you can gauge varies depending on the method. In particular, by examining how much actual demand each method can reveal, you can understand the differences between them at a glance.
| How It Works | Advantages | Disadvantages |
| MVP Launch (Beta Service) | You can gather real user feedback. | You must secure funding for product development and production upfront, and it’s difficult to gauge actual purchase intent. |
| In-Depth Customer Interviews | You can quickly and inexpensively identify customer pain points and product needs. | Asking biased questions may lead to leading answers, and the interview results may differ from actual demand. |
| Social Media Reaction Test | You can quickly gauge trends and customer interest. | Results are influenced by the size of the follower base, and it’s difficult to verify actual purchase intent. |
| Surveys | You can gather comments from a large number of people. | The quality of responses may be low. |
| Crowdfunding (Market Validation via Pre-orders) | You can validate both purchase intent and market viability through actual payments. | Requires preparation (Story and Rewards design) before launching the project. |
3. Why Crowdfunding Is the Most Effective Method for Market Validation
Among the various market validation methods, crowdfunding is the one that allows you to verify market viability through actual payments. While the other four methods are helpful for gauging customer interest and gathering comments, it’s difficult to know for certain whether they will lead to actual purchases. In contrast, crowdfunding operates on a “pre-order, then production” model—where you first unveil your idea, take orders, and then begin production—allowing you to confirm actual purchase intent rather than just general interest. Preparing a project isn’t as difficult as you might think. wadiz’s AI partner, WAi, provides personalized suggestions tailored to your project—from writing your Story to designing Rewards—to help you prepare.
