Painkiller or vitamin: a five-minute test for any idea

The oldest piece of startup advice is to build a painkiller, not a vitamin. It is also the least actionable, because nobody tells you how to tell the difference before you build. Here is a rubric you can run on any idea in five minutes.

The one question that predicts sales

Ask: what happens to this person if they do nothing. If the honest answer involves lost money, a missed deadline, a compliance problem, an angry boss, or hours of dreaded manual work, you have a painkiller. If the answer is “nothing much, life goes on,” you have a vitamin. Pain with a consequence gets bought. Pain without one gets a nod and a closed tab.

The five-minute rubric

Score the idea on five quick checks. Is there a real cost to inaction. Is the problem urgent or on a deadline. Are people already paying to work around it. Can you name the specific person who feels it. Would they buy this quarter, not “someday.” Three or more yeses and you are likely holding a painkiller. Mostly maybes and you are holding a vitamin dressed up as one.

A painkiller (pass)

A tool that files a small business's sales-tax returns automatically. Do nothing and you risk penalties and a stressful scramble every quarter. It is on a hard deadline, people already pay accountants to handle it, the buyer is easy to name, and they will pay the moment the deadline looms. Every box checked. This gets bought quickly and renews without a fight.

A vitamin (fail)

A prettier dashboard that shows a founder their metrics in a nicer layout. Do nothing and absolutely nothing bad happens, they keep using the ugly one they already have. No deadline, no real cost to inaction, no urgent buyer. It might get a “that looks nice,” and a “maybe later” that never arrives. Nice to have is where good products go to starve.

How to turn a vitamin into a painkiller

Sometimes you can. Attach the idea to a consequence the buyer already fears. The pretty dashboard is a vitamin, but “alert me the moment my burn rate says I have under six months of runway” is a painkiller, same data, real consequence. If you cannot find a genuine consequence to attach, that is your answer: keep the tool, change the idea.

Every idea in The Eureka Database is scored on urgency and existing spend for exactly this reason. We would rather show you ten painkillers than a hundred vitamins.
