How to tell if your problem is worth solving
Most ideas that stall in this category stall quietly. The founder sees a real problem, builds a good solution, launches, and hears almost nothing. Nobody was angry or confused. They simply did not care enough to change what they were doing.
The problem category asks one question: does this hurt enough that people will pay to make it stop? It is the most important question in this whole library, and it cannot be answered by asking people whether they like your idea.
Common is not painful
The first trap is confusing how many people have a problem with how much it hurts. Late invoices are common among contractors. Messy closets are common in homes. Forgotten passwords are common for everyone. Being common makes a problem feel like an opportunity. It is not enough.
A painful problem changes behavior. People spend money on it, lose sleep over it, complain about it unprompted, and build clumsy workarounds to manage it. A merely common problem gets a shrug. The Invoice-Chasing teardown in our library shows what happens when a founder builds for a common problem: ten of twelve contractors said late payments were annoying and not worth paying to fix, and they had ignored the free reminder features already sitting in their software.
Why opinions lie
When you describe an idea to someone, three things push them toward a polite yes. They like you. Saying yes costs them nothing. And a hypothetical product always sounds better than a real one with a real price.
That is why "I would definitely use that" is close to worthless. Friends and family are the worst sources of all, because they care about your feelings more than your business. The fix is not to ask better opinion questions. It is to stop asking for opinions and start asking about behavior.
Ask about the past, not the future
Good problem interviews focus on what already happened. Instead of "Would you pay for an app that does this?" ask:
- "Tell me about the last time this happened."
- "What did you do about it?"
- "What have you tried? What did that cost you?"
- "What was frustrating about those options?"
People cannot easily invent a detailed past. If someone says they spent three hours last Tuesday reconciling receipts, that is evidence. If they cannot remember the last time the problem came up, that is evidence too.
Talk to at least ten people who have the problem, and try to make most of them strangers. You will start hearing the same words and stories after five or six conversations. Write down their exact phrases. Those phrases become your marketing copy later.
The three signals of real pain
When you review your interviews, look for three things.
People already spend on it. The strongest signal is money moving. They hire someone, buy a tool, pay for a course, or accept a real cost. If people are spending $200 a month on a clumsy solution, you have a market for a better one.
People already work around it. Spreadsheets, sticky notes, a relative who helps out, a weekly ritual of fixing the same thing by hand. Workarounds mean the problem bothered them enough to act, and they are often the easiest thing to replace.
It happens often. A problem that hurts every week is a business. One that hurts once every few years is a hard sale, because by the time it comes back, nobody remembers your name.
If you find none of these signals, the problem probably is not painful enough, no matter how sensible it sounds.
Painkillers and vitamins
A useful shorthand: painkillers remove a problem people are actively suffering from. Vitamins offer an improvement people agree with in principle and rarely prioritize. Painkillers sell themselves to people who have the pain. Vitamins require persuasion, education, and usually much more marketing money.
Vitamins can work. Many good businesses sell improvements. But a vitamin needs a stronger distribution plan and often a lower price, and you should know which one you are selling before you spend money.
A practical test: if your product disappeared tomorrow, would your customers scramble to replace it, or would they barely notice? Scramble means painkiller.
Who has the worst version
Pain is not spread evenly. Within any problem, some people have a mild version and some have a severe one. Find the severe group. A cleaning service is a vitamin for most households and a painkiller for a family with a newborn and two working parents. Meal planning is a vitamin for most people and a painkiller for someone newly diagnosed with diabetes.
Building for the people with the worst version of the problem gives you buyers who need you now, will pay more, and will tell others like them. You can widen later.
What a strong problem looks like
- People describe it in specific stories with dates and numbers.
- They already spend money or time on workarounds.
- It recurs often, ideally weekly or monthly.
- You can name the group who has the most severe version.
- The cost of not solving it is clear, whether lost money, lost hours, or real stress.
What a weak problem looks like
- People agree it is a problem but cannot recall the last time it mattered.
- Nobody has tried to fix it, even though free or cheap options exist.
- It happens rarely.
- Your evidence comes mainly from friends, family, or your own frustration alone.
- People say they would use your product but hesitate when you mention a price.
Your next step
Before you build anything, have ten conversations about the past. Do not describe your idea until the end, if at all. Write down what people actually do and spend. If the answers are thin, change the problem, change the buyer, or change the idea. It is far cheaper to learn this in a week of conversations than in a year of building.
