You follow the advice properly — market research, differentiation, compliance, brand, 300 bars of stock. Eleven orders come in the first month, nine of them from people who already knew your name. The step that would have told you something was in the guides all along, sitting at the wrong end of the running order.

In 2023 I wrote a product description that was entirely accurate and explained nothing. 100% cotton, 50 x 70cm, machine wash at 30. What I'd never decided was what time of year anyone was supposed to buy it, or why. That decision sets almost everything upstream of it.

A podcast quote about running a business as a proof of concept sent me back through three years of my own trading history. I'd spent two hundred hours making and six telling anyone the business existed. There are only four things that can be wrong when a product business isn't selling, and most people fix the wrong one.

A viral pitch promises print-on-demand will pay your bills while the platform takes a small cut. I checked both claims — one against the published fee schedules, one against five years of my own sales data. The numbers point the other way round.

There's one stack of plates in my cupboard. The John Lewis ones at the bottom are all chipped. The Denby ones on top are older than I am and perfect. Denby entered administration in March, and the reason is written on the price tag.

In fashion, newness is the business model. Small product businesses copy the collection calendar without any of the conditions that make it pay. Here's what that reflex actually cost me.

Someone asked me what they could make with £500. I told them they were starting with the wrong number. The budget can't choose your product — only the objective can.

I found three businesses successfully selling calendars, decided the demand was real, and ordered 25. I sold one. Here's the difference between demand for a category and demand for your product — and why mistaking one for the other leaves you with a spare room full of stock nobody wanted.

I built a product business around an invented customer called Hannah. She never bought anything — because the standard ways of finding a customer don't work when you're selling something nobody needs. Here's what does.

The hardest businesses to walk away from aren't the ones that fail — they're the ones that almost work. Why you can't diagnose a stalled business from your own desk, and the call no spreadsheet makes for you.

Most operational chaos isn't designed — it accumulates, one workaround at a time. The clearest sign is where the work stops: at the one person everything waits on. Why hiring doesn't fix it, and what does.

The most uncomfortable kind of feedback is the one you can't argue with. Which is why founders keep choosing the validation methods that produce the blurriest signals. Blurry signals delay grief — and they delay decisions.

Most founders add new products because they want more to say, not because the business has told them it's ready. Before you brief a supplier or sketch a design, there's one question worth answering honestly: how many strangers have actually bought what you already make? The answer changes everything.

Pip & Nut and All Things Butter spotted the same kind of gap in the food market — and validated it in completely opposite sequences. One sold peanut butter from a weekend stall in 2013. The other built a million-follower TikTok audience before the product existed. Here's how to tell which route fits your product business.

Nobody needs a £38 ceramic bowl. But desire isn't about need — it's about the weight in your hands, the uneven glaze, the feeling that this one was made by a person. Most product businesses reach for the cost sheet when something doesn't sell. The real problem is almost always somewhere else.
