Ideas That Sound Smart for 7 Seconds

Some ideas are obviously bad. These are worse: they sound good. They use the right words, they mention a real trend, and for about seven seconds you can imagine someone nodding along in a meeting.

Then the eighth second arrives. For each pitch below, the first line is the version that sounds smart, followed by the judge’s verdict and the moment the idea falls apart. It is a useful exercise for your own ideas too: if the pitch only works while nobody asks a follow-up question, it is a seven-second idea.

Each pitch was written for this page and judged live on 10 October 2026. Scores and verdicts are the judge’s real output; the seconds 1–7 and second 8 commentary is ours. Checks used: Is My Idea Stupid?.

Buzzwords doing the heavy lifting

Remove the trendy technology from these and nothing is left.

• Blockchain-verified grocery lists, so nobody in the household can dispute who bought the milk.

  Seconds 1–7: Tamper-proof records, applied to a real household argument.

  PRETTY STUPID. 83% stupid

  Great hobby. Tough business.

  Biggest problem: Weak path to making money. · Need 2/10 · Clarity 7/10 · Money 1/10 · Originality 8/10 · Difficulty 2/10

  Second 8: Money potential 1/10. The dispute about the milk is real; the willingness to pay a distributed ledger to settle it is not. The verdict was pretty stupid at 83%.

• Collectible digital certificates of ownership for every coffee you buy.

  Seconds 1–7: Digital collectibles meet a daily habit with huge volume.

  PRETTY STUPID. 79% stupid

  Solves a problem nobody has. Efficiently.

  Biggest problem: Weak customer need. · Need 0/10 · Clarity 4/10 · Money 4/10 · Originality 8/10 · Difficulty 4/10

  Second 8: Need scored zero. You already own the coffee; it is in your hand. A certificate proving it does not make it any warmer.

• An AI that writes your emails and a second AI that reads them, so humans never have to.

  Seconds 1–7: Automation on both ends of the inbox.

  QUESTIONABLE. 54% stupid

  Not stupid, not smart. Just vibes.

  No obvious dealbreaker. Now do the hard part. · Need 6/10 · Clarity 9/10 · Money 6/10 · Originality 6/10 · Difficulty 3/10

  Second 8: The judge rated this only 54% stupid and said there was no obvious dealbreaker. Look closer and the idea removes the humans from the conversation the emails were supposed to be about.

• Personalised vitamins chosen by a quiz about your favourite colour.

  Seconds 1–7: Personalisation is a growth market and quizzes convert well.

  PRETTY STUPID. 84% stupid

  Technically viable. Emotionally unnecessary.

  Biggest problem: Weak customer need. · Need 0/10 · Clarity 4/10 · Money 4/10 · Originality 5/10 · Difficulty 5/10

  Second 8: Need 0/10. The quiz is the only personalised part; your favourite colour has no opinion on your vitamin D. 84% stupid.

Solutions that undo themselves

Each of these fixes a problem by creating the same problem somewhere else.

• A productivity app that blocks every app on your phone, including itself.

  Seconds 1–7: Digital wellbeing, taken to its logical conclusion.

  QUESTIONABLE. 46% stupid

  Great hobby. Tough business.

  Biggest problem: Weak path to making money. · Need 8/10 · Clarity 9/10 · Money 5/10 · Originality 6/10 · Difficulty 4/10

  Second 8: Surprisingly only 46% stupid, with need at 8/10: people really do want help putting the phone down. The logical conclusion is an app you can never open again, which is hard to charge for.

• A meditation app that sends hourly push notifications reminding you to stop checking your phone.

  Seconds 1–7: Mindfulness nudges, delivered where the distraction happens.

  PROBABLY NOT STUPID. 60% not stupid

  Apparently this might actually work.

  Biggest risk: Weak path to making money. · Need 9/10 · Clarity 9/10 · Money 5/10 · Originality 6/10 · Difficulty 0/10

  Second 8: The judge’s favourite on this page: probably not stupid at 60%, with need at 9/10. It still sends a notification to tell you to ignore notifications, which we consider a philosophical problem the scores missed.

• A loyalty program where you earn points for every purchase you return.

  Seconds 1–7: Rewards that cover the whole customer journey.

  PRETTY STUPID. 83% stupid

  Technically viable. Emotionally unnecessary.

  Biggest problem: Weak customer need. · Need 2/10 · Clarity 3/10 · Money 3/10 · Originality 5/10 · Difficulty 1/10

  Second 8: Clarity 3/10, and 83% stupid. Rewarding returns teaches customers to buy things in order to send them back, which is a loyalty program for the warehouse.

• A co-working space for remote workers, located inside each member's own home.

  Seconds 1–7: Flexible workspace with zero commute.

  PRETTY STUPID. 77% stupid

  Great hobby. Tough business.

  Biggest problem: Weak path to making money. · Need 3/10 · Clarity 3/10 · Money 2/10 · Originality 6/10 · Difficulty 4/10

  Second 8: 77% stupid, clarity 3/10. The pitch describes a home office and then charges a membership fee for it.

Real problems, wrong answers

The judge often agreed the problem exists. It disagreed with everything after that.

• A smart fridge that locks itself after 9pm to support your diet goals.

  Seconds 1–7: Behaviour change through smart-home design.

  PROBABLY NOT STUPID. 59% not stupid

  Surprisingly defensible. Don't let it go to your head.

  Biggest risk: Weak path to making money. · Need 7/10 · Clarity 10/10 · Money 5/10 · Originality 8/10 · Difficulty 3/10

  Second 8: One of only two pitches here the judge rated not stupid, at 59%, with 10/10 clarity. We remain worried about the first night someone needs milk for tea at 9:05.

• A subscription for houseplants that are guaranteed to die, so you can stop feeling guilty.

  Seconds 1–7: Emotional design for people who kill plants.

  QUESTIONABLE. 54% stupid

  People will love it right up until the checkout page.

  Biggest problem: Weak path to making money. · Need 6/10 · Clarity 9/10 · Money 5/10 · Originality 7/10 · Difficulty 1/10

  Second 8: Need 6/10, because plant guilt is real. The verdict was questionable at 54%: people will love it right up until the checkout page, which is where the dead plants arrive.

• Dog walkers paid per step, tracked by a GPS collar on the dog.

  Seconds 1–7: Transparent, data-driven pricing for pet care.

  QUESTIONABLE. 65% stupid

  People will love it right up until the checkout page.

  Biggest problem: Weak path to making money. · Need 5/10 · Clarity 8/10 · Money 4/10 · Originality 8/10 · Difficulty 3/10

  Second 8: 65% stupid, mostly on money. Paying per step rewards walkers for long, exhausting walks and leaves small dogs wondering why every outing is a marathon.

• A premium airline seat that reclines fully into the seat behind it, for an extra fee.

  Seconds 1–7: Monetising the comfort upgrade passengers already want.

  QUESTIONABLE. 60% stupid

  Step one is simple. Steps two through ninety are not.

  Biggest problem: Hard to execute. · Need 6/10 · Clarity 8/10 · Money 6/10 · Originality 4/10 · Difficulty 8/10

  Second 8: Execution difficulty 8/10, joint highest on the page. The passenger behind has to be somewhere, and the judge noticed that steps two through ninety are hard.

• A carbon-neutral private jet service for short trips across the same city.

  Seconds 1–7: Sustainable luxury travel.

  PRETTY STUPID. 73% stupid

  Solves a problem nobody has. Efficiently.

  Biggest problem: Weak customer need. · Need 2/10 · Clarity 7/10 · Money 4/10 · Originality 7/10 · Difficulty 8/10

  Second 8: Need 2/10 and difficulty 8/10. The flight would be shorter than the airport security queue, which makes it carbon-neutral mainly in the sense that it barely happens.

Tech nobody would let into their house

Smart devices that are smart in the wrong direction.

• A self-driving shopping cart that follows you everywhere, including out of the store.

  Seconds 1–7: Autonomous retail meets hands-free shopping.

  PRETTY STUPID. 72% stupid

  Step one is simple. Steps two through ninety are not.

  Biggest problem: Hard to execute. · Need 5/10 · Clarity 9/10 · Money 5/10 · Originality 9/10 · Difficulty 7/10

  Second 8: Originality 9/10 and difficulty 7/10. The part about leaving the store is either shoplifting or the world’s most devoted pet, and the judge rated it 72% stupid.

• A smart mirror that rates your outfit each morning and posts the score publicly.

  Seconds 1–7: AI styling with social accountability.

  PRETTY STUPID. 79% stupid

  Technically viable. Emotionally unnecessary.

  Biggest problem: Weak customer need. · Need 1/10 · Clarity 7/10 · Money 4/10 · Originality 9/10 · Difficulty 5/10

  Second 8: Need scored 1/10. Private outfit feedback is a real product; the public scoreboard is a way to make getting dressed feel like a reality show.

• Surge pricing for public library books when they are popular.

  Seconds 1–7: Dynamic pricing balances demand for scarce titles.

  GLORIOUSLY STUPID. 90% stupid

  Maybe run this one past a lawyer first.

  Biggest problem: It might be illegal or harmful. · Need 3/10 · Clarity 3/10 · Money 1/10 · Originality 8/10 · Difficulty 4/10

  Second 8: The worst score on the page at 90%, and the judge flagged it as possibly illegal or harmful. Public libraries exist precisely so that popular books don’t cost more, which takes about one second to remember.

The fastest way to find out whether your own idea is a seven-second idea is to try explaining who pays and why. Our guide on how to pressure-test a business idea walks through the questions the judge asks.
