Stupid Business Ideas

Every business idea has a moment where somebody should have said no. These twenty never had that moment. We made them up on purpose, fed them to the same judge that scores ideas on the homepage, and sorted the results from the merely silly to the truly magnificent.

Read the scores as well as the verdicts. A high stupidity percentage usually comes from one dimension collapsing to zero, most often Need, and the notes under each idea point out which part of the plan the machine refused to forgive.

We wrote all twenty ideas for this page and ran each one through the live judge on 10 October 2026. The verdicts, percentages, roasts and scores are its unedited output. Checks used: Is My Idea Stupid?.

The top tier (85% and up)

The top tier. These ideas don't have one flaw; they are the flaw.

• A taxi service that drives you to exactly where you already are. GLORIOUSLY STUPID. 91% stupid

  Technically viable. Emotionally unnecessary.

  Biggest problem: Weak customer need. · Need 0/10 · Clarity 3/10 · Money 0/10 · Originality 5/10 · Difficulty 3/10

  The highest score on the page at 91%. Need and money potential both scored zero, which is the judge’s way of saying the journey has no destination and the business has no customers.

• A restaurant that serves your food in the order you ordered it, but a week later. GLORIOUSLY STUPID. 90% stupid

  People will love it right up until the checkout page.

  Biggest problem: Weak path to making money. · Need 1/10 · Clarity 4/10 · Money 1/10 · Originality 8/10 · Difficulty 3/10

  90% stupid, and the judge flagged it as low confidence, perhaps because it couldn’t decide whether this was a restaurant or a prank. Originality 8/10; nobody else is willing to do this.

• A dating app that only matches you with people who have already rejected you. GLORIOUSLY STUPID. 85% stupid

  Solves a problem nobody has. Efficiently.

  Biggest problem: Weak customer need. · Need 1/10 · Clarity 6/10 · Money 2/10 · Originality 8/10 · Difficulty 2/10

  Need scored 1/10. The app guarantees a match and also guarantees the match already knows they’re not interested, which is efficient in the worst possible direction.

• A gym that charges you more every time you actually show up. PRETTY STUPID. 85% stupid

  People will love it right up until the checkout page.

  Biggest problem: Weak path to making money. · Need 3/10 · Clarity 5/10 · Money 1/10 · Originality 7/10 · Difficulty 1/10

  Money potential collapsed to 1/10, and the roast says customers would love it right up until the checkout page. A gym that punishes attendance has invented a very expensive way to stay home.

• A moving company that only moves furniture one room to the left. PRETTY STUPID. 85% stupid

  Technically viable. Emotionally unnecessary.

  Biggest problem: Weak customer need. · Need 1/10 · Clarity 4/10 · Money 2/10 · Originality 9/10 · Difficulty 1/10

  Originality 9/10, need 1/10. It is a genuinely new service, in the sense that nobody has ever wanted it. The judge called it technically viable and emotionally unnecessary.

Solidly stupid (70–84%)

Solidly bad, with the occasional score that almost makes sense.

• A doorbell that only rings when nobody is at the door. PRETTY STUPID. 84% stupid

  Great hobby. Tough business.

  Biggest problem: Weak path to making money. · Need 2/10 · Clarity 5/10 · Money 1/10 · Originality 9/10 · Difficulty 3/10

  84% stupid, with 9/10 for originality. A doorbell exists to tell you someone is outside; this one specialises in the opposite, which makes it less of a product and more of a haunting.

• A dry cleaner that only cleans one sleeve of a shirt, for people who roll up the other one. PRETTY STUPID. 83% stupid

  Solves a problem nobody has. Efficiently.

  Biggest problem: Weak customer need. · Need 1/10 · Clarity 8/10 · Money 1/10 · Originality 9/10 · Difficulty 2/10

  Clarity scored a strong 8/10: everyone understands exactly what this is, and that is the problem. The roast says it solves a problem nobody has, efficiently, which is exactly right.

• A car wash for bicycles that requires you to drive the bicycle through inside a car. PRETTY STUPID. 82% stupid

  People will love it right up until the checkout page.

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

  82% stupid. Execution difficulty was only 4/10, which is generous for a process that starts by fitting a bicycle into a car. The biggest problem was money: who pays twice to get their bike wet?

• A bookshop that sells only the last page of every novel. PRETTY STUPID. 81% stupid

  Technically viable. Emotionally unnecessary.

  Biggest problem: Weak customer need. · Need 1/10 · Clarity 4/10 · Money 3/10 · Originality 9/10 · Difficulty 4/10

  Need 1/10. It is the purest form of spoiler, sold at retail prices. The judge’s originality score of 9/10 is a reminder that new and good are different things.

• A podcast where the host reads their own grocery receipts out loud, every episode. PRETTY STUPID. 81% stupid

  Solves a problem nobody has. Efficiently.

  Biggest problem: Weak customer need. · Need 0/10 · Clarity 2/10 · Money 3/10 · Originality 8/10 · Difficulty 0/10

  Need scored zero and clarity only 2/10, because it is genuinely unclear who the audience is. The difficulty score of zero is accurate: anyone with a microphone and a fridge could launch this tonight.

• A cookbook where every recipe says to order takeout, with different photos. PRETTY STUPID. 78% stupid

  Solves a problem nobody has. Efficiently.

  Biggest problem: Weak customer need. · Need 1/10 · Clarity 6/10 · Money 4/10 · Originality 6/10 · Difficulty 1/10

  78% stupid. As a joke gift it might sell a few copies, which is why money potential reached 4/10, but as a cookbook it fails the one test cookbooks have.

• A wall clock that permanently shows the time it was when you bought it. PRETTY STUPID. 76% stupid

  Solves a problem nobody has. Efficiently.

  Biggest problem: Weak customer need. · Need 0/10 · Clarity 6/10 · Money 4/10 · Originality 7/10 · Difficulty 1/10

  Need scored zero. It is technically correct twice a day, which is more than some of the other ideas on this page can claim, but the judge was not won over.

• A subscription service that cancels all your other subscriptions and then itself, every month. PRETTY STUPID. 75% stupid

  Great hobby. Tough business.

  Biggest problem: Weak path to making money. · Need 6/10 · Clarity 7/10 · Money 3/10 · Originality 9/10 · Difficulty 5/10

  The most interesting result in the section: need scored 6/10, because forgotten subscriptions are a real annoyance. It lost points for money potential; a service that cancels itself has a short future.

• Glow-in-the-dark sunglasses for wearing at night. PRETTY STUPID. 74% stupid

  Solves a problem nobody has. Efficiently.

  Biggest problem: Weak customer need. · Need 2/10 · Clarity 7/10 · Money 5/10 · Originality 5/10 · Difficulty 0/10

  Clarity 7/10, need 2/10. Sunglasses that make the dark brighter would at least be an invention; these just make the wearer easier to find.

• Waterproof teabags that keep the tea leaves perfectly dry. PRETTY STUPID. 70% stupid

  Technically viable. Emotionally unnecessary.

  Biggest problem: Weak customer need. · Need 3/10 · Clarity 6/10 · Money 3/10 · Originality 5/10 · Difficulty 1/10

  70% stupid and flagged as low confidence. The product works flawlessly at preventing the one thing a teabag is for.

Under 70%: the judge hesitated

The judge found something here worth arguing about. We are as surprised as you are.

• An umbrella with holes in it, marketed as breathable. PRETTY STUPID. 69% stupid

  Solves a problem nobody has. Efficiently.

  Biggest problem: Weak customer need. · Need 3/10 · Clarity 6/10 · Money 4/10 · Originality 6/10 · Difficulty 0/10

  Only 69% stupid, partly because execution difficulty scored zero: making this umbrella is easy. Selling it twice to the same person is not.

• Scented candles that smell like a candle that has just been blown out. PRETTY STUPID. 69% stupid

  Solves a problem nobody has. Efficiently.

  Biggest problem: Weak customer need. · Need 3/10 · Clarity 4/10 · Money 5/10 · Originality 5/10 · Difficulty 1/10

  69% and low confidence, with 5/10 for money potential. Novelty candles are a real category, which kept this one out of the top tier despite smelling like the end of a birthday party.

• A bakery that sells bread already toasted, buttered and dropped butter side down. QUESTIONABLE. 65% stupid

  Technically viable. Emotionally unnecessary.

  Biggest problem: Weak customer need. · Need 4/10 · Clarity 8/10 · Money 5/10 · Originality 6/10 · Difficulty 1/10

  65% stupid, questionable rather than pretty stupid. Need reached 4/10, possibly because pre-toasted, pre-buttered bread is half of a reasonable idea. The dropping is the other half.

• Pre-melted ice cream sold by the litre, for people in a hurry. QUESTIONABLE. 63% stupid

  Solves a problem nobody has. Efficiently.

  Biggest problem: Weak customer need. · Need 3/10 · Clarity 8/10 · Money 5/10 · Originality 5/10 · Difficulty 2/10

  63%, and the judge rated clarity 8/10. Melted ice cream is mostly a sweet milk drink, which is a product people already buy, just not under this name.

• A hotel with no beds, for people who just want to be away from home. QUESTIONABLE. 60% stupid

  Already exists. Probably with a better logo.

  Biggest problem: Already exists, with little to set it apart. · Need 5/10 · Clarity 5/10 · Money 6/10 · Originality 4/10 · Difficulty 3/10

  The least stupid idea on the page at 60%, and the biggest problem was not need but competition: Already exists, with little to set it apart. Cafés, libraries and long walks have been offering this service for free for centuries.
