Your company now has a cable bill for software, and it climbs every year. The Owned Office is the other option: one small server in your building, running open-source software you own. Your history moves onto it, and an independent checker proves to the penny that nothing was lost. You meet it in three moments — Move, Run, then Watch.
You own the hardware, the data and the software. Every credential is yours from day one, export is always on, and when you want a change you call the engineer who built it.
I build the software too — you can browse a captured demo suite at acme.darn-tech.com. DArnTech built it and ran it; what you see there is a snapshot taken on 18 September 2026, so the pages read but the forms don’t submit.
Not a chatbot bolted to your website. The AI in an Owned Office runs on your box, reads your own paperwork, and takes over one chore you name on the dry-run day. Each proof below is something I built and use, and two of them you can open yourself.
Your contracts, quotes, job history and the things only one person remembers, answerable in plain English. Search that reads meaning, not keywords, over your own files.
Every shop has one job people redo by hand. We pick it together on the dry-run day and automate that one first, because the chore that hurts is different in every shop.
The model sits on the box with everything else. Your documents stay in your building, there is no per-seat bill, and nobody trains on your data.
The fourth thing AI does here is watch. Machines check themselves overnight; you read one short page each morning. A check that can’t run says so instead of passing.
Three things you can open and check yourself. Each one is work already done, not a plan.
A complete company, 1,191 transactions over two fiscal years, moved from real QuickBooks Desktop into ERPNext and verified to the penny by an independent checker. Every artifact archived, the whole run reproducible.
Read the proof →Booking, job boards, quote approval and customer status pages: the front-office layer of the Owned Office. DArnTech built it and ran it; what you open is a snapshot taken on 18 September 2026, so the pages read but the forms don’t submit.
Open the demo →Darren writes up what he is building and what broke, in public. That record lives on LinkedIn. This page is the short version.
Read along →You would be buying a box that runs your company, so the question is whether the person who built it can be trusted with that. For fourteen years I designed, built and ran automated systems in buildings where stopping was expensive. Here is where that happened.
The Owned Office is for an owner-operated business with a systems deadline already on the calendar. If that is you, write and tell me what the deadline is.
Most of this work reaches a business through someone already inside it — an accountant, a broker, a consultant who knows the books. If that is you, say so when you write; the partner route is the one we build around.
No one has bought an Owned Office yet. The migration proof and the captured demo are public, so you can check the work before you talk to me.
