Most of the entrepreneurs I've met over the years didn't fail because they were lazy. Quite the opposite. They worked day and night, invested their savings, built a product they'd dreamed of for months. The problem was simpler and crueller than that: nobody ever asked them whether anyone wanted what they were building — and they themselves never dared to ask that question early enough.
That's the most expensive kind of mistake. Not because the idea wasn't good, but because it was never really checked.
There's a widespread belief that market analysis is something you write. A chapter in a business plan, a document for the bank, a table to satisfy a clerk at a grant competition. In that logic, market analysis comes after the decision — when the idea has already been made, the money already mentally spent, and all that's needed is a paper confirmation. That's how analyses get written that convince no one, least of all the entrepreneur themselves.
Real market analysis isn't a document. It's a process by which you check whether real demand exists before you invest money. It isn't a paper confirming you're right, but a test trying to prove you're wrong — while it's still cheap to find out.
This article isn't theory. The aim isn't for you to learn definitions, but for you to start asking better questions after reading it. Because an entrepreneur who knows how to ask the right question before investing is worth more than one who knows all the definitions but asks them too late.
What quality market analysis actually means
I've already said that market analysis isn't a document, but that claim is worth clearing up fully, because of all the misunderstandings in business planning this one costs the most.
In the most common perception, market analysis is a chapter. Something you write because you have to — for the bank, for a competition, for a clerk who wants a table with the market size and a list of competitors. In that logic, the analysis comes at the end, once the decision is already made, and serves to justify it. Those are the analyses that sound convincing yet convince no one — least of all the person who wrote them.
Quality market analysis does something completely different. It isn't a chapter, but a process. A series of concrete checks by which the entrepreneur, before investing, tries to find out whether real demand exists: who would pay, how much, why they'd choose you of all people, and whether it pays off in the numbers. It isn't written to dazzle anyone, but so the entrepreneur themselves makes a better decision — and while changing one's mind is still cheap.
The difference is in the direction. Bad analysis starts from a conclusion and looks for data to confirm it. Good analysis starts from a question and lets the data steer it, even if they lead to the conclusion that the idea should be abandoned. The first protects the ego. The second protects the money. All the methods in this text — searches, conversations, reviews, test sales — are tools of that second kind of analysis.
Why good business ideas fail anyway
When you look at analyses of why new ventures fail, the same causes go round in circles: a lack of real demand, running out of money, the wrong team, competition too strong, prices set wrongly. CB Insights analysed hundreds of failed startups and the absence of a market need appears just as often as financial problems. What's important to understand: "we ran out of money" usually isn't the cause. It's the consequence. Money usually runs out for those who spent months pouring it into something the market wasn't asking for.
Harvard Business Review named it well — a "false start" — pushing a product onto the market before anyone seriously dealt with the customer. The team starts building a solution before checking whether the problem exists. And then they're surprised when no one is interested in the solution.
Here it's important to separate two things that are often confused: bad execution and a bad market.
Bad execution — a weak product, disorganised sales, chaotic operations — accelerates failure, but is rarely the cause in itself. When real, strong demand exists, the market tolerates imperfections surprisingly well. I've seen businesses that function despite improvised processes and a mediocre product, simply because they solve a problem that genuinely hurts someone. And the reverse — I've seen impeccably executed products that died in silence because no one needed them.
A good product can fail in a bad market. A bad product in a good market sometimes survives.
That brings us to two concepts worth understanding, but without a textbook tone. Product-market fit is the moment when a product genuinely satisfies strong demand — when customers don't choose you out of politeness, but because they need you. Before that comes something simpler, problem-solution fit — proof that the problem is painful enough and that your solution makes sense to the customer, even before you've fully built everything. Entrepreneurs who skip that first check and immediately build a full product most often hit empty space.
There's also a part of this story that's talked about less, and that's decisive: psychology.
People rarely fall in love with a market. They usually fall in love with their own idea. And falling in love has side effects. The first is excessive optimism — the conviction that, in our case, everything will go faster and easier than the statistics suggest. The second is confirmation bias, the tendency to look for information that confirms what we already believe and avoid that which refutes us. An entrepreneur in love with an idea unconsciously chooses interlocutors who will support them, reads articles that prove them right, and rationalises bad test results: "customers haven't understood yet", "it just needs a bit more marketing".
The third bias is perhaps the most dangerous — sunk cost, the feeling that we mustn't give up because we've already invested too much. The more money and months go into an idea, the harder it is to admit it should have stopped. And that's exactly why you have to check early, while the stake is small and the ego hasn't yet fused with the project.
The first question isn't "Is the idea good?"
Most conversations about business ideas start from the wrong question. "Is my idea good?" sounds reasonable, but is almost useless — because everyone answers it in the affirmative, the idea's owner most loudly of all.
The real question goes: Are there enough people willing to pay for it?
The difference isn't cosmetic. "A good idea" is a judgement about the idea. "Who will pay" is a fact about the market. The first can go round in your head indefinitely. The second can be checked.
This is where beginners most often break. They show the idea to friends, family, a few people from work, and receive praise. "Great idea!", "I'd definitely use that!", "That's exactly what I'm missing!" Those sentences feel like validation, and are actually the worst kind of false security.
A compliment isn't an order. A person who tells you the idea is great risks nothing. A person who takes out their wallet risks something. That's why the only serious confirmation comes from behaviour, not from words — from a subscription, a pre-order, a deposit, a signed trial contract. Everything else is courtesy.
The same goes for a sentence I hear at least once a month: "Well, people would need this." Maybe they would. But "they would need it" isn't market analysis — it's a hypothesis, and yours at that. As long as it rests on your feeling, rather than on what people actually look for, spend and do, it remains merely a nice assumption.
The strongest signal of demand isn't what people say, but what they already do. If your potential customers already pay for an imperfect, improvised solution to the same problem — that's gold. It means the problem exists, that it's painful enough for money to be set aside for it, and that there's room for you to solve it better. A workaround people use is worth more than ten enthusiastic conversations.
If no one is willing to pay, the problem isn't marketing.
Do you know who your real customer is?
We won't do buyer personas and demographic tables here. That turns into an exercise of imagination that looks professional and helps nothing. What you really need to answer is simpler and harder.
First: who exactly are you selling to? Not "everyone who might need it", but a concrete, recognisable group you can describe and, more importantly, reach. Because "everyone" in practice always means "no one". When you try to speak to everyone, your message becomes so general it hits no one, and the marketing budget evaporates into thin air.
Second, and this is often overlooked: who makes the purchase decision, and who uses the product? With small purchases it's the same person — a sole trader buys a tool for themselves. But the moment the business becomes more serious, those roles separate. In a company, the one who uses the product (say an engineer or production manager) is often not the one who signs the order (a director, procurement). If you build your offering only for the user while the decision is made by a third party with completely different criteria — ROI, risk, alignment with procedures — you can have delighted users and not a single order.
That's why a serious check has to involve talking to both sides. The user reveals where it really hurts. The one who pays reveals what it takes to convince them to open their wallet. Those are two different conversations and two different stories, and the deal closes only when both work.
How to check whether real demand exists
This is the part everything else exists for. Now we'll move from questions to methods — but not as a list of tools, rather as a logic. Each of these approaches answers a different question, and it's worth understanding why you're doing something, not just how.
The digital traces the market leaves
Google searches are the cheapest first step. If people are actively looking for a solution to your problem, it leaves a trace in the search engine — there are queries, there are ads, there's competition. The mere presence of ads is a good sign: no one pays to advertise for a term no one searches. A search won't give you an exact number, but it shows you the landscape — who's already there and how they speak to the customer.
Google Trends goes a step further and shows the dynamics over time. Is interest rising or falling? Is there seasonality that can help (or hinder) your launch? For small, specific niches Trends tends to be blind because there isn't enough volume — but for broader topics it gives a useful sense of direction.
Competition is probably the most misread signal of all. We'll come back to it separately, but remember already now: if there are several firms that have lived off the same problem for years, that isn't a reason to panic. It's proof that the market exists.
Reviews — and competitors' reviews, not your own — are the most underrated source of truth on the internet. Positive reviews tell you what you have to deliver at least as well. Negative ones are even more valuable: in them, customers literally write what annoys them about existing solutions. Slow delivery, poor support, hidden price increases, inconsistent quality. Every such complaint is a potential hole through which you can enter the market.
Conversations with customers are worth more than assumptions
Conversations with customers remain the foundation. But there's one rule that separates a useful interview from a waste of time: ask about the past, not the future. "Would you buy this?" is a useless question — people predict they'll be better than they are. "How did you solve this problem last time? How much did it cost you? What annoyed you most?" reveals the truth, because past behaviour is a far better predictor than good intentions.
LinkedIn, Reddit and forums give you something interviews can't — raw, unfiltered language with which people describe their own problems. That's doubly useful: you validate demand and at the same time capture the exact words you'll later use in ads and on your page. A caveat: the extremes are always louder, and silence doesn't necessarily mean the problem doesn't exist — perhaps it's just being solved off the internet.
When interest becomes real demand
Everything listed so far checks whether interest exists. But interest isn't a purchase. So comes the second, more serious level — checking the willingness to pay.
Here a rule applies that sums up this whole story: the best way to check an idea isn't to ask people whether they like it, but to try to sell it to them. Everything else is guesswork with good intentions.
A landing page is the cheapest way to measure this. A simple page that clearly says what you offer and asks for a concrete action — a sign-up, a pre-order, a waiting list. A good sign-up rate is a signal, but caution: a sign-up isn't a purchase. The strongest version is the one that asks for a small, symbolic payment or a deposit, because only then do you measure the willingness to part with money, not just curiosity.
An MVP — the simplest version of a product that lets you learn something with minimal stake. It needn't be a product in the real sense. Dropbox validated its idea with a simple video before building anything. Zappos started with the founder manually buying shoes in a shop and sending them to customers — no warehouse, no system, just to check whether people would buy shoes online at all. That wasn't technology, but an experiment.
A pilot project and test sales lead you to the real truth: the whole path from interest to a paid invoice. A small batch, a limited number of clients, a single trial month. There you see things no survey shows — how much it really costs to acquire a customer, where the process gets stuck, what people do when it's time to pay.
Pre-orders and crowdfunding close the circle because they ask for money up front, which is the most honest test of all. If people pay for something that doesn't yet exist, the demand is real. Just be aware that this also comes with an obligation — a public promise that has to be kept.
The logic behind all of this is the same: you climb a ladder from the cheapest signals (searches, conversations) toward ever more expensive but ever more reliable ones (payments, orders). The aim isn't to gather proof that you're right. The aim is to find out, as cheaply as possible, if you're not.
Competition isn't always bad news
Beginners fear competition. The experienced look for it.
There's a widespread misconception that the ideal market is one where you're alone — "we're first, we have no competition". In nine cases out of ten that isn't an opportunity, but a warning. An empty market usually means one of two things: either there's no demand, or there's a hidden obstacle — regulatory, cultural, technological — because of which no one has succeeded. Entering completely empty terrain is riskier, not less risky.
Competition isn't always a problem. Sometimes it's the best proof the market exists. If several firms have lived off the same problem for years, someone is clearly paying. Your task isn't to avoid them, but to understand where they're weak.
And to understand that, you have to stop looking only at prices. Price is the easiest to compare and therefore the least useful. A serious competitor analysis looks at the wider picture: how the offering is structured, what the terms and guarantees are, what after-sales support is like, how high the level of trust and reputation is. In business with companies, it's precisely those "soft" elements — trust, delivery reliability, the quality of communication — that often decide more than the price list.
That's where the opening for a market gap appears. You'll find it precisely in what the competition does badly. If everyone ignores small clients, there's a niche. If everyone has poor support, there's your advantage. If everyone competes on price and no one communicates quality, there's your positioning.
And here comes a rule worth framing: don't try to win by being the cheapest. There can always be someone cheaper, and a price war is a war won only by whoever can sustain losses the longest. Differentiation — being different in a way that means something to the customer — is far more sustainable than trying to be cheaper.
How big is the market really?
There are three terms used to measure market size, and they sound more complicated than they are. I'll explain each in a single sentence.
TAM is everything — the total revenue if you served absolutely everyone who might need the product. SAM is the part of that you can realistically serve, given where you are, what you offer and how you operate. SOM is what you can actually win in the foreseeable future, with your resources and with all that competition around you.
In pitch decks, TAM is the favourite because it's the biggest and looks the nicest. "The market is worth three billion euros!" It sounds impressive and means almost nothing. The question is never how big the market is in theory, but how much of it you specifically can reach, and at what price.
A large market has a hidden trap: it's almost always both saturated and expensive to enter. To be noticed at all in an enormous market, you need an enormous budget, and a customer is expensive to acquire because you're fighting everyone. A small, well-chosen niche does the opposite — you can tailor the product precisely, speak the language of exactly that group and spend less to reach a customer.
It's almost always better to be a big fish in a small pond than invisible in the ocean. Dominance in a narrow niche gives you margins, loyalty and a starting position from which you can later expand into adjacent segments. An attempt to conquer the ocean straight away usually ends with no one noticing you.
Can you actually make money on that idea?
Demand is necessary, but not sufficient. There are ideas with clear demand on which you simply can't make a decent living. That's perhaps the hardest lesson, because it lets you down precisely when you think you've won — customers come, orders arrive, and too little is left in the account.
It all starts from willingness to pay — how much the customer is really willing to set aside, which depends on the value they see and on what alternatives they have. This is where the most guessing happens. People set a price by feel or by looking at the competition, with no testing at all. And price can be tested — with different offers, different bundles, watching where the customer says "yes" and where they have second thoughts.
What's most often completely overlooked is the full cost per unit. Not the purchase price — the full cost. Material, labour, packaging, delivery, platform commissions, marketing per customer, the discounts you gave to close the deal. Only once you add all that up do you see how much is actually left for you. And only then can you calculate where the break-even is — the point at which revenue covers all costs and after which you start earning.
There's a temptation, especially at the start, to sell with almost no margin — just to "get going", to gather a reference, to enter the market. As a short, clearly limited test that sometimes makes sense. As a business model — never. Sales that barely cover costs aren't growth, but a postponement of the problem. The more you sell without a healthy margin, the deeper you sink, just faster.
A high customer acquisition cost isn't necessarily a problem in itself — if it's matched by a sufficiently large long-term value from the customer. The problem arises when you pay more to bring in a customer than you'll ever earn on them. That's arithmetic that can't be made up for with willpower or with marketing.
Test the idea before a big investment
If you remember only one sentence from this whole text, let it be this: it's better to lose five hundred euros on testing than fifty thousand on the wrong investment.
The most expensive mistakes arise when an entrepreneur skips the check and immediately invests seriously. They buy equipment, sign a long-term lease, hire people, launch a big campaign — all of it before anyone has confirmed that the solution solves a real problem for a real customer at a price that pays off. When things then go badly, on the table is a heap of fixed costs and no way to get out quickly.
Testing reverses that order. Instead of investing and then seeing, first check and then invest. The tools are the same ones we talked about — a landing page, an MVP, a pilot, a small batch, test sales, pre-orders, advertising with a small budget to measure how much it really costs to bring in a customer. The difference is in the intent. You're not building a product, you're buying information. And as cheaply as possible.
There's an old saying from operations I love, because it maps perfectly onto this topic: Excel will put up with almost anything. The market won't. In a spreadsheet, every idea looks profitable. The numbers obediently rise, the margins fall into place by themselves, customers arrive on schedule. The market is less polite. It will tell you the truth, but only if you ask it — and testing is exactly that question, asked while the answer is still cheap.
Red flags you shouldn't ignore
There are signals that, if you're honest with yourself, tell you to stop or at least pause. The trouble is that an entrepreneur in love rationalises them most easily. Here are the most important and why they're dangerous.
No one is willing to pay. If you've gone through conversations, a landing page and an attempt at test sales, and no one has taken out their money — that isn't a communication problem. That's the answer.
You don't know who your customer is. If, to the question "who buys this", you answer "well, everyone who needs it", you haven't started yet. That's a sign the idea exists only in your head, not on the market.
There's no differentiation. If you differ from the competition only in being new or in being cheaper, you have no reason for existence the customer would recognise.
The margins are too thin. If even on paper you barely break even, reality will be worse — it always is. A business without breathing room in its margin has no reserve for error, and there's always error.
The acquisition cost is too high. If every new customer costs you more than you earn on them, growth doesn't save you — it accelerates the failure.
The initial investment is too large relative to what's been verified. The more you have to invest just to start, the more important it is to validate beforehand. A large stake in an unverified idea is the most expensive kind of hope.
There's serious regulatory risk. Certificates, permits, standards and regulations can kill an idea that's otherwise perfect. Better to find that out before investing than after.
Everything hangs on one customer. If a single client brings most of your revenue, you don't have a business — you have a dependency. The day they leave, the business is gone.
None of these flags is necessarily a death sentence on its own. But each demands an honest answer, not an excuse. A rule worth adopting: first look for the reasons the idea won't succeed. Only if you don't find them, start looking for the reasons it might.
The most common entrepreneur mistakes
Over the years the same mistakes repeat so predictably they could almost be written out in advance. Here are the ones that cost the most.
Being in love with the idea. The biggest of all, and the source of most of the others. When you love an idea too much, you stop checking it and start defending it.
Looking for confirmation instead of the truth. You show the idea to those you know will support you and avoid those who might tear it down. That way you collect compliments and call it research.
Analysis that never leaves the screen. The internet is a great start and a bad end. Articles, forums and competitors' pages can keep you in the "research phase" for months without ever talking to a real customer or trying to sell anything.
Checking only with friends and family. They love you and wish you well, so they'll say what you want to hear. Their opinion is warm, humanly valuable and, in business terms, almost worthless.
A focus on the product instead of the customer. Months on features, technology and perfecting details, and almost no time with the people who are supposed to pay. The product thus becomes ever better at solving a problem that perhaps troubles no one.
The belief that marketing will solve everything. Marketing is an amplifier. It amplifies what already exists. If clear value and demand exist, it will accelerate growth. If they don't, it will only spend money faster on letting more people find out they don't need the product.
Investing before validation. The root of all the expensive mistakes. Everything listed above becomes bearable if you invested little. It becomes a catastrophe if you invested everything.
Frequently asked questions
How do I check a business idea before investing? Start from the question of who will pay, not whether the idea is good. Check whether people are looking for a solution (searches, forums), what competitors and their customers do (reviews), then test the willingness to pay through a landing page, pre-orders or a small test sale. Climb from cheap signals toward more expensive but more reliable ones.
How do I know whether a product will sell? You'll know for certain only when someone actually pays. Everything before that is a signal — interest, searches, conversations — that raises or lowers the probability but doesn't replace it. The strongest early signal is if people already spend money on a weaker solution to the same problem.
How do I do a market analysis for a small business? Without academia. Define a concrete customer, check whether demand exists through searches and conversations, analyse the competition (especially their weaknesses from reviews), estimate the size of the part of the market you can realistically reach, and check whether it pays off in the numbers. The aim is to make a better decision, not to fill in a document.
How much money do you need to validate an idea? Often surprisingly little — a few hundred euros for a simple page and test advertising, plus your time for conversations with customers. The whole point of validation is precisely that it's cheap relative to the investment you're avoiding.
What is an MVP and do I have to build one? An MVP is the simplest version with which you check something at minimal stake. It needn't be a finished product — it can be a video, a manually delivered service or a landing page. It's often smarter to start with that than to build a full product.
Is competition a bad sign? Most often it's a good one. It means someone is paying and the market exists. The bad sign is an empty market, because it usually hides either a non-existence of demand or an obstacle others failed to clear.
What if everyone says the idea is great, but no one buys? That's a clear answer, not a riddle. Praise costs nothing, buying costs something. When there's a gap between words and behaviour, believe the behaviour.
How do I set a price for a new service or product? Start from the value to the customer and the alternatives they have, not only from your costs. Test the price with different offers and bundles. And always first calculate the full cost per unit so you know the limit below which you lose.
How long should I validate before launching? Long enough to check the key assumptions — whether the problem exists, who pays, whether it pays off — but not so long that you hide in analysis. Validation has a shelf life: the moment you have enough to decide, the decision is made.
Can I validate an idea if I'm in a niche with few people? Yes, even more easily. In a small niche you can often talk directly to a large share of all potential customers. A few serious conversations and one test sale are worth more than any table.
Conclusion
Market analysis isn't a tool for convincing a bank or satisfying a clerk at a competition. It is, above all, a tool by which an entrepreneur tries to prove to themselves that their idea makes sense — while it's still cheap to find out.
The aim of this text wasn't for you to learn the definitions of product-market fit or the difference between TAM and SOM. The aim was to change the order of questions in your head. So that before you invest, you first ask who will pay. So that before you build, you first check whether the problem exists. So that before you fall in love with a solution, you take an honest look at the market you intend to sell it to.
The biggest risk is never having a bad idea. A bad idea is quickly recognised and abandoned. The biggest risk is investing time, money and energy in an idea you never seriously checked — because it looks just as good as a good one, right up until it's too late.
So, before everything else: look for the reasons the idea won't succeed. If, after an honest check, you don't find them — only then start looking for the reasons it might.
And if you want to develop the individual steps of this check in more depth, it's useful to continue with two related topics: what product development looks like in practice I've described in the text Private label for beginners — from idea to shelf, and when it comes to the numbers, it all comes together in the article How to prepare financial projections for a business plan.
It's precisely on that question — checking business ideas and analysing markets before investing — that I work with entrepreneurs through Meridian Consulting. But whether you do it on your own or with help, the most important thing stays the same: that in the end you honestly know whether you're checking your idea or merely believing it will succeed.
