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.

A client emailed me this week — her long-term supplier had quoted higher than usual, and she was ready to start over. I told her not yet. There's one question worth asking before you switch suppliers, and the answer almost always changes the conversation.

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.

You sit down to write handover notes before a week off — and realise you can't explain your own job. Most product businesses run on a person, not a system. Here's what "documented" actually means in practice, and where to start.

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.

"Can we make it cheaper?" is never really about cost. It's about what changes when the price drops — and whether the product still works when you've changed it. Here's what that looks like in practice.

"Lightweight cotton, natural colour" can mean ten different things depending on who's reading it. That's not a factory problem — it's a specification gap. Here's how to write a brief that removes the guesswork before sampling begins.

Six weeks into development, that question isn't about colour anymore. It's about whether your process can handle change without turning it into delays, extra cost, and a very awkward conversation with your factory.

Nobody needs a £28 candle. And yet entire industries are built on products people want but don't need. Most business advice doesn't distinguish between need-based and desire-based businesses — and that's where founders get stuck. Here's the validation framework that actually works.

Ordering 25 units instead of 5 was the right production decision. It was also completely wrong. The MOQ wasn't the problem — the sequence was. Here's the calculation most product businesses skip before placing a production order.
