Across every industry, organisations invest significant time, money and expertise developing products they believe customers will want. Yet one of the biggest challenges in product development remains, how do you know when you’ve found genuine product-market fit?
The difficulty lies in separating signals from noise. Markets are constantly changing, customer expectations evolve rapidly and new technologies create waves of excitement that can be difficult to interpret. Businesses often receive encouraging feedback during the early stages of a product’s development, but understanding whether that feedback represents genuine demand or simple interest is an important distinction.
Many products don’t fail due to poor execution; they fail because organisations mistake market curiosity for evidence that they have solved a meaningful problem. It’s an understandable mistake, early signs can be incredibly encouraging – prospective customers book demos, investors ask questions, industry peers share positive feedback, website traffic grows and social posts gain engagement. The market appears interested. However, while interest can open the door, product-market fit requires something much deeper.
This curiosity is often driven by novelty. People are naturally drawn to new ideas, emerging technologies and innovative concepts. They want to understand what something does and how it works. The current AI-driven environment is amplifying that curiosity further. Organisations are exploring possibilities, investigating opportunities and seeking to understand how new technologies could affect their businesses. The challenge is that curiosity creates noise and many products fail not because the idea was poor, but because the signals were misread.
True product-market fit occurs when a product solves a meaningful problem for a specific group of people and they actively seek it out because they need it. Customers are willing to pay, they return repeatedly and they recommend it to others. Growth becomes increasingly driven by the value of the product itself rather than the effort required to promote it.
One of the most useful questions to test product-market fit is what would you do tomorrow if this product didn’t exist? The answer will give you a concrete workflow which reveals whether you’re replacing something painful or if you’re just offering something that is a nice to have. It will also help you to understand where your real competition is.
Businesses pursuing product-market fit should focus less on collecting positive feedback and more on uncovering evidence of real behavioural change. Are customers changing their processes because of the product? Are they investing time and budget? Are they returning without being prompted? Are they disappointed when the product isn’t available? These are far stronger indicators than expressions of interest alone.
This is particularly important in uncertain economic conditions. Organisations have less tolerance for experimentation and are increasingly focused on measurable outcomes. Products that solve genuine problems will continue to find buyers. Products built around assumptions or market excitement will struggle once the initial curiosity fades.
For leaders developing new digital products, the lesson is clear. Treat curiosity as an invitation to learn, not proof that you’ve succeeded. The goal is not to build something that captures attention, it is to build something customers would genuinely miss if it no longer existed. That is the point at which curiosity becomes traction, and traction becomes sustainable growth.
At Leighton, we work with product leaders and technology teams to reduce uncertainty around product-market fit. Through structured product discovery, strategy and iterative delivery we help organisations validate whether a problem is commercially meaningful before committing to large-scale build.
