Why you should test before you spend
Most businesses launch products backwards. They invest in inventory, branding, a website, and advertising, then wait to see if anyone buys. When the product flops, they have lost thousands of dollars and months of effort.
Smart founders test demand first. They find out whether real people will pay real money for their product before committing significant resources.
Method 1: Sell before you build
The simplest validation test is to attempt to sell the product before it fully exists. Create a landing page describing what you offer, the price, and the benefits. Drive a small amount of traffic to it and see if people try to buy.
You can use a simple "join the waitlist" or "pre order" button to gauge interest without fulfilling orders immediately. If nobody clicks, you have saved yourself from building something the market does not want.
Method 2: Commission agents as market testers
This is one of the most underutilised validation strategies. List your product on a platform like Zepys with a commission structure, and let independent agents try to sell it. These are experienced salespeople who will quickly tell you if the product resonates with buyers.
If agents apply and start generating sales, you have validated demand with zero advertising spend. If agents struggle or lose interest, that is valuable market feedback, also at zero cost.
The agents are effectively your focus group, except they are testing with real purchase decisions rather than hypothetical survey responses.
Method 3: Direct outreach to potential buyers
Pick up the phone or send emails to 50 people who match your ideal customer profile. Describe what you are offering and ask if they would buy it. Not "would you be interested?" which always gets polite yeses, but "can I send you an invoice?" which reveals actual purchase intent.
This is uncomfortable for many founders, but it provides the most honest feedback you will ever get.
Method 4: Partner with existing sellers
Find businesses or individuals who already sell to your target market. Offer them a sample of your product and a commission for each sale they refer. Their willingness to promote it, and their customers' willingness to buy, tells you whether you have something viable.
Method 5: Small batch testing at markets
For physical products, farmers markets, pop up shops, and local events are low cost ways to put your product in front of real buyers. Rent a table for $100, bring your product, and see what happens.
The immediate face to face feedback is invaluable. You learn not just whether people buy, but why they hesitate, what questions they ask, and what improvements they suggest.
Interpreting results
Do not expect perfection in a test. A 5% conversion rate on a landing page or three sales out of fifty cold calls is enough to suggest there is a market worth pursuing. The goal is to distinguish between "nobody wants this" and "some people will pay for this."
Moving from test to scale
Once you have validated demand, you scale through the channel that worked best in testing. If commission agents drove sales, add more agents. If direct outreach worked, systematise it. Test cheap, then invest in what works.
