What this is

One of our published methods, written in plain language: what it can do, when to use it, what goes in and what comes out.

Why it matters

Most methods are published as papers or code. This one is written so you can decide whether it fits your problem before you invest time in it.

How to use it

Read the page top to bottom. If it matches your question, use the online tool - or subscribe and run it on your own data.

What you get

A clear answer on what the method does and does not do, plus a live curve from our own demand series. Free to read.

What this is

A handbook of our published methods - one page each, in plain language, with a real-data curve under every one.

Why it matters

Most methods are published as papers or code. These are written so a shop owner can read them straight through and know when to use one.

How to use it

Read the short version on each card. Open the method that matches your question. Each page tells you what goes in and what comes out.

What you get

Nineteen methods you can actually apply, each with a live curve from our own demand series. Free to read.

Demand curve read by this method
A live reading from our own demand series - the shape of the signal this method works on. 570 industries are tracked daily; this is one of them.
No jargon — only "what it can do, when to use it, what goes in and what comes out, how to use it, who it is for". The goal: a shop owner can read it straight through.

📈 Every page carries one real-data curve (new)

These 19 pages now each come with a chart drawn from real data — under each chart there is one line saying "what this chart shows", and the data source and generation time are labelled so you can check them against the numbers. To see the 30 small chains that string one need from beginning to end, go to Life Chain visualisation →

1What pages exist now (19 in total, grouped by theme)

Every page follows one piece of real evidence: either a pairing produced by running an algorithm against a need, or a real number from the city × industry gap table, or measured data from an overseas campaign report. No evidence, no page.

First: does anyone want it (demand and value)

Industry, lane, risk (is this line still worth entering)

You want to do it — can you actually pull it off (landing)

How to catch traffic (putting your words in front of the right people)

People and spread (where you are now, whether others will spread it for you)

3Algorithms with no page yet (awaiting scenario / component class)

A page of its own is written only for needs where "someone will really use it" and that can be traced to one piece of real evidence. Filler pages are not written.

The ones with no page yet fall into three groups:

The complete list and the reasons are in the "awaiting scenario / component class list" in this delivery's report.
