Prior — is it worth building?

What would it do? Who pays for it? What do they do instead today? Which country first? What can you put behind it? What do you already have? Optional

Customers, a mailing list, a trade you are known in, a business that already sells to these people. This is remembered between ideas because it is about you rather than about this one.

What would count as this working?

This changes the answer, not the tone. A market worth £2m a year is a good living and a dead end, depending on which of these you picked.

How would you reach them?

The honest answer. "I don't know yet" is a real answer and changes the verdict.

Add this to the anonymous record. Your idea is never included — only the category, the verdict, and the companies and prices found. That builds a picture of which markets are filling up and how fast.

What it does

Any chat will answer “is this worth building”. None of them will go and check.

Gives you no score out of a hundred.

Every other tool in this category leads with one. A score is a number with no source, which is the one kind of number worth not trusting.

Reads every price back off the seller’s own page.

A link is only a promise that a page said something, and it is just as convincing when the address was invented. Every price here says whether the figure was still there today.

Makes what was found look different from what was guessed.

Before you read a word. Market sizes are nearly always guesses, and they are marked as guesses rather than dressed up.

Looking for who already does this… Takes a minute or two. You can switch away, but keep the tab open — closing it stops the search.
