I Ordered 25 Calendars. I Sold One.

I once ordered 25 calendars because other people were successfully selling calendars.

I sold one.

That was an expensive lesson in the difference between category demand and product demand.

Before I launched, I’d done what every validation framework tells you to do – research your market and competitors. So, I found businesses already selling similar products I wanted to sell. They looked successful. They seemed to be making money. Demand, therefore, existed.

The logic was solid.

But it wasn’t.

What I’d actually proved was that people wanted their products.

I had proved absolutely nothing about whether anyone wanted mine.

And that is the difference between building a business and stocking your spare room with a product nobody wants.

Category demand and product demand

The mistake I made was assuming these were the same things.

And yes, sometimes they are.

If your boiler breaks in December (true story, it happened to me!), you need someone to fix it. You don’t particularly care which heating engineer turns up. You care that the boiler works again.

That’s why competitor research works so well for problem-solving businesses.

If three local heating engineers are fully booked, you’ve learned something useful. People need heating engineers. The demand already exists. If you’re competent, reliable and reasonably priced, some of that demand can become yours.

The competitors are all drawing from the same pool of broken boilers.

A candle, however, is different.

The fact that people buy candles from Diptyque doesn’t mean they’ll buy yours. The fact that people buy pyjamas from Toast doesn’t mean they’ll buy yours. The fact that people bought illustrated calendars from The Printed Peanut didn’t mean they would buy mine.

All it proved was that those businesses had managed to create demand for their specific products.

That’s the distinction I missed.

I validated demand for the category. I never validated demand for my product.

Why desire businesses work differently

A premium candle isn’t solving an urgent problem.

The £6 jasmine candle from Tesco F&F Home makes the room smell nice too.

Pay £63 for the Jasmine Classic from Diptyque and you’re buying taste, identity, status — the reason a gift feels like a gift. Different customers will describe it differently, but the point is the same.

The purchase is driven by wanting, not needing. And when a purchase is driven by wanting, competitor success becomes much harder to interpret.

Three successful plumbers tell you people need plumbing.

Three successful candle brands tell you people wanted those candles.

Those are not the same thing.

One proves the demand was already there. The other proves the product created the demand.

The signature isn’t proof

The usual response is: but mine will be different. My style, my story. I’ll put my signature on it and people will come.

And that might be true. In a desire business, your signature matters. It’s often the entire reason someone buys from you instead of someone else. But distinctiveness is not the same as desirability. You can be unmistakably yourself, completely original and still leave every stranger cold.

A signature might create demand for your product. It is not proof that it will.

The gap between those two is where the money goes.

What competition actually proves

None of this means you should ignore competitors. It means you should read them for what they can actually tell you.

Three thriving candle brands tell you people are willing to pay premium prices for candles. That’s valuable information. It tells you the category is commercially alive.

You can learn even more by looking at what sells, not just who's in business.

What’s consistently sold out? What gets restocked? What keeps selling despite price increases? What is just as valuable second-hand?

That’s real evidence because it’s based on real people spending real money. What competitors still can’t tell you is whether anyone wants yours. That evidence doesn’t exist in their sales figures.

It only exists once your own product is in front of real strangers — and then it comes from what they do, not what they say. Anyone can say ‘I’d definitely buy that.’ Far fewer will actually pay. The actual price paid, not a polite hypothetical. The person who comes back. The person who chooses yours with three alternatives sitting right next to it.

That’s the only validation that’s ever counted for a desire product. And it can’t happen before the product exists — which is exactly why no amount of competitor research gets you there first.

So the question was never whether three other people are doing this. In a desire business there are always hundreds. The category is rarely the thing in doubt.

The real question is whether anyone wants your specific version of that thing. Competitors can’t answer that. Only the product itself can.

24 unsold calendars taught me the difference.

I had the category. I never had the product.
