Instead of verifying how well the product addresses a genuine customer pain point, we rush straight into the execution phase. The result? We build a solution that we perceive as flawless, but which actually has no place in the consumer’s ecosystem of needs. At Yetiz, we believe in the effectiveness of delivering results, not just “doing” projects. Meanwhile, without a solid foundation in Problem-Solution Fit (PSF) and Product-Market Fit (PMF), the chances of success drop drastically.
Brutal statistics vs. overoptimism
The data is unforgiving. Startup statistics clearly show the scale of the challenge—these companies are always in the spotlight, and their failures (whether collapsing or scrambling for capital) are plain for all to see.
However, based on my experience, these insights apply just as much to new products and services developed within established firms and corporations. Research from CB Insights and Startup Genome [1] points to a stark reality: 42% of startups fail for one simple reason—a lack of actual market demand. It’s not a lack of technology, a weak team, or an empty bank account that serves as the primary business killer; it’s the fact that we are building things nobody wants.
What’s most striking, though, is the disconnect between theory and practice. Almost every founder declares that idea validation is critical, yet the statistics show that in the heat of the moment, almost no one actually does it. It is a startling dissonance between knowledge and action—a classic “escape forward” trap.
Why do we ignore the obvious? The mindset traps
There are many reasons for this state of affairs, most of which are rooted in psychology and the cognitive biases described by Daniel Kahneman, among others.
-
Confirmation bias. Instead of seeking the truth, we seek confirmation of our vision. When a client says “Great!”, we take it as validation. When they say “This is useless,” we assume they simply don’t understand our brilliant concept. This is why 80% of app features remain “dead weight”—the team “knew better,” despite data showing their lack of utility.
-
Fear of confrontation. We are afraid of the answers. We avoid market conversations to escape hearing that our “life’s work” makes no sense. Often, feedback from family and friends replaces rigorous research—which is frequently dismissed as a luxury or a whim—leading the business straight into a dead end.
-
The sunk cost fallacy. The more time and money we invest, the harder it is to pivot. We cling to the original idea even when the data is screaming: “Change direction!”. Sometimes this stems from existing commitments: to investors, employees, or early adopters.
-
Overconfidence. The “I know better” syndrome. We overestimate our ability to predict market needs, especially if we already have past successes under our belt. Remember: if no one is buying, it’s usually because we are solving a problem people don’t have—not because the world doesn’t understand us.
(However, this issue isn’t strictly black and white. There are famous examples of startups and products where the creators persisted despite everyone telling them it couldn’t work—and they won.)
The pressure that kills quality
Often, failures stem not only from the founders’ mindset but from the external business environment itself.
-
Pressure from stakeholders. Investors and executives often demand revenue “by yesterday.” Validating PSF takes time and primarily generates knowledge, not cash. In many companies, this stage is misinterpreted as a lack of progress. Funders want to invest in finished solutions, forcing startups to cut corners: they conduct 50 interviews instead of 500 because “there’s no time, we must build.” They ignore market signals because “scale is all that matters” and jump straight to MVP development because “investors want to see a product.” There is also a pervasive fear of pivoting or killing a project early. Such a decision is still often viewed as a failure—by both creators and stakeholders.
-
A lack of standards. While Go-To-Market strategies and MVP development processes are well-documented, the validation of the problem itself (the pre-MVP phase) is still often characterized by organizational chaos.
-
Rigid adherence to roadmaps. Creators often follow a predetermined roadmap (e.g., a feature list) rather than market feedback. This leads to a notorious problem: 80% of features are used rarely or not at all. Massive budgets are squandered on expanding unnecessary functionalities instead of deeply understanding the core problems customers expect the product to solve.
-
The wrong metrics. We focus on the number of features delivered or registration counts instead of looking at retention and real customer value. At the ideation stage, traditional financial indicators are blind—what matters here is interest and engagement. Traditional firms, and increasingly startup investors, analyze projects through the lens of revenue, profit, and business valuation. However, at the idea stage, these metrics say nothing about the actual value for the potential customer, making any projections highly unreliable. Before traction is significant enough to use financial data, we must rely on indicators of customer interest: retention, CAC, MRR, and ARR.
The consequences: why it matters
Even the best Go-To-Market (GTM) strategy cannot save a project built on flawed assumptions. It usually leads to “burning cash” and results in either total failure or a late-stage pivot—which carries significantly higher costs.
The “Test, Learn, and Scale” strategy: how to avoid burning capital
To avoid the trap of building solutions nobody needs, we must shift our approach to product development. Here are my recommendations:
- The 7-day cheapest test: spend one week on lightning-fast experiments. Dedicate each day to a different scenario testing your riskiest assumptions. Set hard success criteria and face the results head-on—no excuses, no relativism.
- 50 interviews is the minimum: not two, not five. It’s only around the 50th conversation that you gain statistical confidence that the problem is real and not just a “hallucination.”
- Validation by wallet. Talk is cheap. Introduce a payment element (pre-order, early access) during the conversation stage. If a customer sees real value, they will be ready to make a commitment. This approach also allows you to calculate the actual market size; TAM (Total Addressable Market) without this validation is often a delusion.
- Avoid outsourcing your MVP phase: founders should be directly involved in every stage—from customer interviews to MVP design and validation. This allows them to catch non-verbal feedback, understand customer intent, and notice nuances that never make it into a report. It’s in these moments that you spot the things that “don’t click,” the lack of “chemistry,” or where the “solution feels over-engineered.”
Conclusion: validation is not a cost—it’s an insurance policy
Building a product in isolation from reality is the fastest way to burn through resources. In a world where most startups fail due to a lack of market demand, ignoring PSF and PMF is a strategic blunder that no one can afford.
The key to success isn’t the mindless delivery of features according to a roadmap; it’s the courage to confront your vision with painful feedback and hard data. Early-stage validation is the only foundation upon which a business can truly scale. Instead of building solutions for problems that don’t exist, let’s invest in dialogue. It is the only way to win the battle for market attention.
Key Takeaways
- Validation is your insurance policy. A staggering 42% of projects fail because they solve problems that don’t exist. CB Insights statistics are unforgiving: without rigorous research, your project is nothing more than an expensive hypothesis.
- View the needs-assessment phase as an investment, not a cost. This stage protects your budget from burning out. PSF generates knowledge that is far more valuable than premature revenue.
- Beware of mindset traps. Confirmation bias and the fear of negative feedback are the greatest enemies of innovation. If a customer says your solution is useless—listen. It’s your chance for a low-cost pivot before you sink millions into a product.
- Don’t outsource market conversations. As a decision-maker, you must be directly involved in building and validating the MVP. Only direct interaction allows you to catch the nuances that no outsourced report can capture—non-verbal feedback and the customer’s true intent.
- Implement a “Test, Learn, and Scale” strategy. Replace rigid roadmaps with rapid experimentation. A minimum of 50 market interviews and “wallet validation” (e.g., pre-orders) provide the hard data you need to actually scale the business.
- Measure what matters. At the early stage, traditional financial metrics can be misleading. Focus on retention and real user engagement. If no one is coming back to your product, no Go-To-Market (GTM) strategy will save it.
