Complaints, not trends
An opportunity is a problem that costs someone and keeps coming back
It repeats
Many people, not one
A workaround exists
Someone already spends time on it
Money already moves
They pay for a fix they dislike
It costs something now
A deadline, a fine, lost customers
A business opportunity is a problem that costs people time or money and keeps coming back: they complain about it in public, patch it with a workaround, or pay for a fix they dislike. Look for those signs in what people write, not in trend lists. A trend tells you what is being talked about; a complaint tells you what someone would pay to stop. Our pain library sorts the problems we find into 13 topics, and on 2026-09-29 the largest held 631 sourced problems.
Four signs of a real opportunity
One complaint is an anecdote. The more of these signs a problem shows, the stronger it is, and the one it cannot do without is a cost: money, time or a deadline already involved.
Where we find them: the pain library
We search public sources for what solo operators and small businesses say is going wrong, keep the source where there is one, and group the problems into topics. The bars show how many sourced problems each topic held on 2026-09-29. Each label opens the topic, so you can read the problems themselves.
A big topic is not a better opportunity. Its count partly reflects how broad the words that match it are, so read the size as a place to start, not a ranking. The smaller topics, such as real-estate & property pains with 37 problems, can hold a narrower buyer who is easier to reach. Either way, the topic is where you start reading, not the answer.
What the largest topics look like
Each topic in the library comes with a short description of the problems it gathers. Here are the three largest, in the library's own words, as a sense of what a topic of sourced complaints reads like before you open it.
Opportunity or trend?
Trend lists are easy to find and easy to mistake for opportunities. The difference shows up in four questions.
| Question | A trend | An opportunity |
|---|---|---|
| What it tells you | What people are talking about | What someone would pay to stop |
| Who is behind it | An audience, often of other founders | A buyer with a named job and a cost |
| How long it lasts | Until the next thing gets attention | As long as the job exists |
| What to do next | Watch it | Ask the buyer for a costly action |
How to read a complaint
When you find a problem, write four things next to it before you think about a product:
- Who has it. A job title or a kind of business, not "people".
- What it costs them. Hours, lost customers, late payments, a fine.
- What they do now. The workaround or the tool they already pay for.
- How often it comes back. A problem that returns every week can carry a subscription; one that happens once rarely can.
Keep the link to the complaint next to your notes, so the idea cannot quietly rewrite the evidence later. If you cannot fill in the second line, the complaint is not yet an opportunity. The guide on where to find customer problems covers the places worth searching, and the trending page ranks sourced problems by how often our searches found them.
Mistakes when reading complaints
Complaints are the best raw material and the easiest to misread. Three mistakes come up again and again:
- Counting noise as demand. A thread with hundreds of replies may be a handful of people arguing. Count the separate people who describe the problem, not the messages.
- Listening to people who will not pay. A complaint about a free tool often means the person wants it free and better. Look for complaints from people who already pay for something.
- Hearing the solution instead of the problem. When someone writes that they wish a tool did X, the useful part is why they need X. The feature they imagine is one answer; yours can be another.
Turn one into a test
An opportunity becomes a business idea only when a buyer acts on it. Write the narrow version, one buyer with one costly job, and ask for something that costs them: a pre-order, a deposit, a paid first delivery. If nobody acts, the problem was real but the offer was not, and you learned it for the price of a message. If you are not sure which opportunities fit you, the founder read starts from your time and skills and points to directions worth reading first.
Common questions
How do you find business opportunities?
Read what people complain about in public and look for problems that repeat, that people patch with workarounds, that they already pay to fix badly, or that carry a deadline or a cost. Those are problems someone would pay to stop.
Is a trend a business opportunity?
Not on its own. A trend shows what people are talking about; an opportunity is a specific buyer with a costly problem. A trend can tell you where to start reading, but only a buyer's action can test an opportunity.
How do I know if a business opportunity is real?
Write down who has the problem, what it costs them, what they do now and how often it returns. Then ask that buyer for a costly action, such as a pre-order or a paid first delivery.
