If you are curious about the market reaction before making the product, please check if it is applicable below.
- I want to make sure it's really sold before I make the product
- It's hard to know the real demand from surveys alone
- I made the MVP, but I'm curious about the market's reaction
- I want to verify an idea without risk of failure
Is there a way to check if it will be sold before making the product?
You can also make the product first and then check the market reaction, but if demand is lower than expected, the production cost and inventory burden may increase. That's why many brands go through a market verification process that checks the market reaction first before launching! In this article, we will compare representative market verification methods such as MVP, in-depth customer interviews, SNS tests, surveys, and crowdfunding, and introduce ways to check demand with actual payment and success stories.
1. Why market verification is needed before product launch
When preparing a product, the first thing that comes to mind is, 'Will this product really sell?' This is because it's hard to know until the launch whether an idea will lead to a real customer's purchase even if it's good! So, many brands first check actual customer reactions and purchase intentions through market verification before product launch in order to reduce the risk of starting a business.
2. Compare 5 Market Validation Methods Before Product Launch
There are five main ways to verify the market. Each method has a different level of market response. In particular, if you look at how far you can check the actual demand together, you can understand the difference between each method at a glance.
| Way | Advantages | Weakness |
| MVP Launch (Beta Service) | You can check the actual user feedback. | We need to secure product development and production costs first, and it's hard to confirm the actual intention to purchase. |
| In-depth Customer Interview | You can check the inconvenience and needs of the product for a quick and low cost. | If you ask biased questions, you will get induced answers, and the content of the interview and the actual demand may be different. |
| SNS Response Test | You can quickly grasp trends and customer interest. | It's affected by the size of the followers and it's hard to check whether they actually bought it or not. |
| Survey | You can gather the opinions of many people. | The quality of the response may be low. |
| Crowdfunding (pre-order based market verification) | You can verify your purchase intention and marketability together through actual payment. | We need to prepare for the project opening (story and reward design). |
3. Why Crowdfunding Is Best for Market Verification
Crowdfunding is a way to check marketability through actual payment among many market verification methods. The other four methods help us to confirm the customer's interest and opinions, but it's hard to know exactly if it will lead to an actual purchase. On the other hand, crowdfunding is a pre-order and post-order production method that releases ideas first, receives orders, and then produces them, so you can check your actual purchase intention, not your approximate interest. Preparing for the project is not as difficult as you think. Wadiz AI partner WAi proposes what I need to prepare for the project, such as story writing and reward design, according to my project.

5. A good idea to validate the market with crowdfunding
- Ideas with MVPs and prototypes (specimen, sample) that are still before they are completed: Wadiz can fund with just core functions or prototypes, so you can check the market reaction first before you complete the product.
- Ideas to check actual purchase demand: Funding is marketable through actual payment, not just interest or opinion.
- The idea of minimizing risk even if you fail: It's a pre-order, post-production method, so you can test the market response with relatively little risk while reducing the initial capital and inventory burden. In addition, if the target amount is not reached, there will be no supporter payment and platform usage fees, so you can reduce the burden of the results and verify your ideas.
- Ideas to verify the market not only for products but also for services and apps: You can check the market response based on actual payment in various fields such as apps, AI services, contents, and online classes as well as real products.
