Every new AI chat starts from zero — it doesn't remember your last decision, your numbers, or why you're on this strategy. Day Zero OS is an Obsidian vault built as shared memory for you and your AI assistant, so it can actually help run your business instead of improvising without context every session.
### 2026-07-22 — Killed the $14/mo tier before launch
Decision: Ship one-time only; revisit subscription after real sales.
Reasoning: at $24 one-time vs $14/mo for a strict superset
of value, a rational buyer should always subscribe one month and
cancel. The $24 tier was dominated. Fix the pricing before scaling.
Reversible: Yes.
01Every founder rebuilds the same scaffolding
Your AI forgets everything
Re-explain your whole business every new chat, or watch it improvise without context.
No decision log
Six months in, you can't remember why you made the call that's now not working.
No real dashboard
KPIs live in your head, or scattered across three half-finished spreadsheets.
No SOPs
You redo the same task from scratch every time because nothing got written down.
02What it looks like
A ready-to-use Obsidian vault, structured around 8 folders that each do one job — Command, Strategy, Projects, Operations, Knowledge, Reports, Finance, Templates. Every file capped short and cross-linked, so it stays usable at 10 notes or 10,000. (That decision-log entry on the right is a real one, not a mockup for the page.)
03How you actually use it
Orient. Open the Home file. It links to your objectives, KPIs, what's active, what's blocked — point your AI at it and say "read this first."
Do the work. Building, selling, fixing — whatever today's task is.
Log the decision. Any real call (pricing, direction, a pivot) gets one entry: what you decided, why, what you considered instead.
Keep the numbers honest. One tracked KPI beats five nobody updates.
This is the literal system running the company that built Day Zero OS.

05Questions
Do I need to know how to code?
No. It's markdown files in folders — if you can use a text editor, you can use this.
What's Obsidian?
A free note-taking app that opens folders of markdown files as a linked vault. Download it here — Day Zero OS is built for it, but the files are plain markdown, so they're not locked in.
What if it's not for me?
Email within 7 days of purchase for a full refund, no questions asked.
Do I have to use AI with this?
No — it works run by hand as a well-organized way to operate a company. AI is an accelerant, not a requirement.
