Kudteminabuan – The most common mistake in entrepreneurship is building a product before validating the market. Founders fall in love with an idea, spend months or years developing it, and then discover that no one wants to buy it. This pattern is so common that it has become a clichĂ©, yet it repeats constantly. The validation first principle offers an alternative: before investing significant time or money in building a product, validate that there is a market willing to pay for it. The principle seems obvious, but its execution requires discipline that many founders lack.
The Validation First Principle: Why Market Demand Must Come Before Product Development

Validation begins with the problem, not the solution. Founders who start with a solution are already biased; they have fallen in love with a particular approach before understanding whether the problem is real. The validated founder starts with the market, identifying problems that people are actively trying to solve. Active problems are those that people already spend time, money, or emotional energy addressing. The problem that someone has already paid to solve is the problem worth solving.
The simplest validation method is conversation. Talk to potential customers about their problems, not about your solution. Ask about their current workflows, their frustrations, what they have tried, what they have paid for. The goal is not to sell but to understand. Founders who pitch their solution in validation conversations learn nothing; they receive politeness rather than insight. Founders who ask genuine questions and listen deeply learn the information that will shape their product development.
The next level of validation is pre-selling. Before writing code, before manufacturing, before any significant investment, see if anyone will pay for the product that does not yet exist. A landing page with a purchase button, a waitlist, a Kickstarter campaign—these are validation mechanisms that provide evidence beyond conversation. Pre-sales that require actual payment are the strongest validation; words are cheap, but wallets reveal genuine interest.
The concept of the Minimum Viable Product (MVP) is often misunderstood. The MVP is not the smallest product that could possibly be built; it is the smallest product that delivers value and tests the core assumption. The MVP should be built as quickly and cheaply as possible, not because quality does not matter but because the goal is to learn, not to launch. The validated founder builds the smallest thing that can teach them whether the market wants what they are building.
The iteration cycle that follows validation is where the business takes shape. Early customers provide feedback that shapes the product. The features that seemed essential in the founder’s imagination may prove irrelevant; the features that seemed minor may become the core value. The validated founder is not attached to their initial vision; they are attached to solving the customer’s problem. The product evolves based on evidence rather than ego.
The false validation trap is dangerous. Friends and family who say they would buy are not validation; they are being polite. Interest without payment is not validation; words are cheap. Press coverage and awards are not validation; they do not predict revenue. The validated founder seeks the hardest evidence: strangers paying money for something that does not yet exist, or early customers who continue paying over time.
The validation first principle does not eliminate risk; entrepreneurship always involves uncertainty. But it dramatically reduces the risk of building something that no one wants. The founder who validates before building has evidence; the founder who builds before validating has hope. Evidence is a better foundation for business than hope. The validation first principle is not complicated, but it requires discipline that most founders lack. The ones who practice it are the ones who survive.
