Build and sell a vault you own.
Ten modules, 48 lessons, every template. Built in public — the numbers further down this page are real, including the bad ones.

Who this is for
- You already know something people would pay for, and you have never packaged it.
- You want one file you can sell, not a course platform, a membership or a community to run.
- You would rather publish something unfinished and fix it in the open than polish it for another six months.
- You are selling from the EU and want the invoicing, tax and withdrawal-right parts handled rather than ignored.
Who it is not for
- You want income without making anything. Every module here is work, and the early ones are the least fun.
- You have no subject yet. Module 1 helps you choose one, but it cannot give you expertise you do not have.
- You want an audience first. Nothing here builds one for you; it assumes you are willing to sell to a small one.
- You need someone to check your work. There is no coaching, no community and no reply-by-Friday promise. It is a file.

How it works
- 1
Pay
Card payment through Stripe. Nothing to create an account for.
- 2
Download
A link arrives by email straight afterwards. It is a folder of Markdown files, not a login.

Open it in Obsidian
Drag the folder in as a vault. Obsidian is free, and everything inside is plain text you can edit, rename and keep.

Work the map
Module 0 sets the order. Ten modules, 48 lessons and eight templates, in the sequence they are meant to be done in.

Checkout is not connected yet, so both buttons are inert. Stripe arrives in the next phase and the prices here will be read from it rather than from a file.
Inside a note
Excerpts from four written notes. Eight of the vault’s 48 lessons are written; the remaining 40 are outlines to be completed before launch.
How To Read The Graph
The graph view draws one dot per note and one line per link between notes. That is the whole mechanic.
Why it sells
A graph is proof of structure that works at a glance and survives compression. Someone scrolling Instagram sees a dense, coloured web for half a second and reads it as this person built a real system — before they have read a single word. No claim is made, so there is nothing to disbelieve.
Excerpt from the note
Why Most People Never Pick
The bottleneck is almost never the build. It is the picking.
The reframe
You are not looking for an untouched idea. You are looking for a crowded market you can enter from an angle nobody else has. Competition is proof of demand. The angle is where your advantage lives.
Excerpt from the note
The Knowledge Audit
A worksheet, not a lesson. Open a new note and answer these properly — in writing, not in your head.
The five questions
- What have you done in the last two years that took you more than 20 hours to figure out? Anything. A course, a move, a system, a job, a skill, a piece of software, a bureaucratic process.
- What do people ask you about? Even casually. Even once. Especially things you find boring because you already know them.
Excerpt from the note
Demand Check Before You Build
Before you write a single lesson, spend an hour proving someone wants this. The goal is not certainty, it is avoiding the obvious no.
Four checks, one hour
Search the problem, not the product. Type the pain into Google, YouTube and TikTok in your buyer's own words. Results with real engagement means demand. A dead search means either no demand or nobody phrases it that way — find out which.
Excerpt from the note
Who made this
I'm building and selling one digital product in public.
This vault is the system I'm using, and the numbers above are what it has actually done so far.
Questions
Do I need Obsidian?
Yes, and it is free for personal use on Mac, Windows, Linux, iOS and Android. The vault is a folder of Markdown files, so you can also read it in any text editor — you just lose the graph and the links.
What exactly do I get?
A folder of Markdown files: ten modules, 48 lessons and eight templates. No video, no platform, no login. You download it once and it is yours.
What is the difference between the two tiers?
Vault teaches you to build it. Build hands you the parts: everything in Vault, plus the Next.js sales page repo, Stripe checkout, webhook and delivery code, an importable ManyChat comment-to-DM flow, and the EU compliance pack. The pack contains Impressum, Datenschutz, AGB and Widerrufsbelehrung templates, checkout waiver wording and Stripe Tax configuration. Both tiers are a one-time purchase of downloadable files.
Is this a subscription?
No. One payment, one download. There is nothing to renew and no account to cancel.
Can I get a refund?
At checkout you tick a box agreeing to immediate delivery, and that waives the 14-day right of withdrawal for the download — EU law works this way for digital files, and without the waiver you could not have it straight away. If the file will not open, or it is not what this page describes, reply to the delivery email and you will get your money back.
