A Problem Worth Paying For
A problem is worth building on only when people already spend money, time, or clumsy workarounds trying to escape it. · 10 min
An idea can feel valuable while it sits in your head, because nothing there argues back. A problem is different. A problem worth building a business on leaves evidence in the world before you arrive: people already spend money, lose time, or rig up clumsy workarounds trying to escape it. This folio is about reading that evidence honestly — and about resisting the problems that only sound worth solving.
Guess before you learn
A friend says your idea is great, a stranger keeps a bucket by the door to catch a roof leak, and you personally find parking annoying. Which is the strongest sign of a problem worth building on?
The bucket. It is a workaround — a complaint written in action — and it cost the stranger real effort to set up. Praise is free, and your own annoyance is a sample of one. If you picked the friend, that instinct is common: encouragement feels like evidence. The next section separates the two.
9–12
3–5
A real problem leaves marks you can see. People already spend money on a clumsy fix, or waste time doing it the hard way, or build little workarounds to get by. A problem with none of those marks might be one that nobody truly cares about — yet.
So before you fall in love with a solution, go looking for the marks. Where are people already paying, waiting, or patching things together? That is where a business can stand.
6–8
Three signals tell you a problem is worth building on. First, money: people already pay for something to escape it, even a poor substitute. Second, time: they lose hours to it and would value those hours back. Third, workarounds: they have rigged their own clumsy fix, which is a complaint written in action. One strong signal beats a dozen people saying the idea sounds nice.
9–12
The signals share a root: revealed preference. What people already do with their money and time is stronger evidence than what they say they would do. Stated interest is cheap; a receipt, a wait, or a home-made workaround costs something, and that cost is the proof. A problem backed only by agreement in conversation has not yet been tested against anyone's real budget.
K–2
Your crayon keeps rolling off the desk. You catch it, put it back, catch it again. That catching is a problem. If a friend paid you a sticker to make it stop, the problem was real.
A problem people already try to fix is a real one. A problem nobody bothers with is just a wish.
Undergrad
Frame the problem as a job people are trying to get done. When a job is important, frequent, and poorly served by current options, people already hire something imperfect to do it — a rival product, a manual routine, another person. That existing spend is both your evidence base and your benchmark. The size of the problem is bounded by what people currently pay, in money or effort, to accomplish the job today.
Postgrad
Distinguish stated from revealed preference rigorously. Surveys of purchase intent are notoriously weak predictors; observed prior behavior around the job — spend, substitution, effort — carries the signal. Beware founder confirmation bias: the people you interview and the answers you notice are both filtered toward your hope. A problem is validated not when people admire it but when their past allocation of scarce money and time already treats it as worth solving.
problem worth solving
A problem people already spend money, time, or workarounds trying to escape. The spending is the evidence.
Why is this true?
Why trust what people already do more than what they say they want?
Because doing something costs money, time, or effort, and people spend those only on problems they truly feel. Words cost nothing, so agreement in conversation can be pure politeness.
The most expensive mistake in early business is building for a problem people only say they have. In conversation people are generous: they agree, they encourage, they imagine they would buy. None of it costs them anything, so none of it is proof. What you are hunting for is behavior that already happened — a payment, a wasted hour, a workaround built without you. Behavior has a price, and a price is what makes it evidence.
So a problem earns your time when people already spend to escape it. Before the next folio, find one problem where money, time, or a workaround is already changing hands — that is the ground the rest of this course builds on. Next, you will learn to confirm a problem by talking to the people who live it, without accidentally selling them your solution.
Practice — new ink and old, interleaved
1.A cafe owner throws out unsold pastries every night and grumbles about the waste. Which signals are present?
2.A shop loses about $15 of spoiled stock every day it is open, 6 days a week. How many dollars does the problem cost over a 4-week month?
3.In one sentence, why is your own enthusiasm weak evidence that a problem is real?
4.Name the three signs a problem is worth paying to solve.
People already spend money on a poor fix, lose time to it, or build a workaround.
