Memory
Knows your business before you ask.
Your notes, decisions and open tasks, read first, every time.
OwnOS, the business operating system built around a founder
Your whole business, run from one place built around you.
One private workspace that knows your business, drafts in your voice, protects your clients and waits for your yes. It comes preset, so you skip months of setup.
Built with you in four sessions, on your own computer. You go from typing prompts to an AI that runs whole jobs for you.
45 minutes with me, live on my own system. We sketch yours together.
“Best decision I’ve made all year.” Melinda Mayne, founder, Pet Let
ChatGPT here. Claude there. Prompts everywhere.
Folded into one place.
Old chats, prompts, notes and documents, gathered once and sorted.
Filed in order, so it knows your business.
Nothing sends without you.

Watch it work
A sales call in. A proposal out.
From my own system. The proposal is anonymised.
Real recording of a 16-minute run, sped up and cut to 12 seconds. OwnOS was then called Chief of Staff.
Named his chief of staff Marty
“It keeps track of where every lead and job is at, drafts emails and proposals in our actual voice, and remembers the details I’d normally lose between sessions.”
Founders
In their own words.
Built with founders at

Tried building her own first
“Then I found Arek and his fully resolved, beautiful system, and his Do It With You approach. Best decision I’ve made all year.”
For him, not with him
“Arek really unlocked how to connect it all together and make it work for me, not just with me.”

I built OwnOS to run my own two agencies. I build yours with you, so you can run it without me.
What it is
One workspace, not another pile of skills.
Most AI setups are a handful of prompts and skills that don’t know about each other. OwnOS is one workspace around you: your business, voice, rules and clients in plain files on your computer, with the system that uses them already set up.
The tools you use, held in one layer around you.
A morning
Say “morning”.
One word, and your connected inbox and calendar come back sorted.

Hi Priya, thanks for getting in touch. Thursday mornings are open in November. Want me to hold one for you?

An illustration. The names are made up.
What it does
Your AI can already do the work.
OwnOS is what lets you trust it to.
Voice
Writes the way you write.
OwnOS studies your writing and drops the words you’d never use.
Learning
Learns from your edits.
Change a draft and OwnOS takes note. Corrections you repeat become rules.
Reviewers
A second pair of eyes, built in.
One reviewer reads all that goes out. Another checks money and dates, a third what OwnOS builds.
Portable
Plain files on your computer.
Runs on Claude, and works with ChatGPT through Codex. Built for the much smarter models coming, and your records go with you.
A normal day

A passing thought

Responsible by design
Four values OwnOS works by.
Kept on your own computer, secure, trusted and honest, and built to protect your clients. You can only hand work to something you trust.
- SecurityOwnOS is told to treat emails and documents as information, never as instructions.
- TrustedSeparate checks for your standards, for money and dates, and for its own work.
- HonestyOwnOS is told to push back rather than flatter, and to say it’s done only after checking.
- Being usefulOwnOS gets the work ready. Your one job is to decide.
These are rules, not magic. AI can still get things wrong, which is why the yes stays yours.
What does OwnOS do without asking?
Tap one to see who decides.
Waits for your yes
Once sent, nobody can take it back, so you decide.

Questions.
What happens to my ChatGPT and Claude work?
It comes with you. Gather it in one folder and your chief of staff reads it, then sorts it. Projects that already work can stay.
Do I need to be technical?
No. You won’t write code. You need a Mac or Windows PC, a paid AI plan (I suggest Claude at about US$100 a month; the US$20 plans run out) and two free tools the setup walks you through.
What about my data?
Your AI provider sees the text it works on. Setup covers whether your plan lets them train on it. The OwnOS kit has no tracking and reports nothing back.
What if I stop?
Nothing switches off. The licence doesn’t run out, your data stays yours, and a build with me includes 12 months of updates.
What does it cost?
It costs more than a course or a pack of prompts, because you get the whole system, preset, and the training to run it yourself. Two ways to get it, with prices on one page: built with me over four sessions and two follow-ups, or on your own from the OwnOS kit. Teams and companies are scoped on the audit, then quoted in writing. See both, with prices
Doubts welcome. Bring them to the audit.
You talk first: what you use today and what you’re unsure about. Then I show you my own system running, and we sketch yours. If OwnOS isn’t right for you, I’ll say so.
45 minutes with me, live on my own system. No slides, no pressure.
