The CoreOS method
What is CoreOS?

The short answer
CoreOS is a business operating framework built by Nick Thorpe over a decade of running his own companies. It has four elements: strategy, accountability, mindset and systems. It is applied through his Momentum coaching and Cabal mastermind, and the free CoreOS Scorecard gives you a 12-question diagnostic against it.
CoreOS is the framework that sits underneath everything Core Business does. Nick Thorpe built it over a decade of building and scaling six and seven figure companies across property and investment: a lettings and property management business in Yorkshire, a property portfolio of his own, an invite-only property network and an investment fund. Before that, he served 16 years as a British Army officer. CoreOS is what those years taught him, organised into a framework an owner can actually run a business with.
What are the four elements of CoreOS?
The four elements are strategy, accountability, mindset and systems. Nearly every problem in an owner-led business, Nick’s own included, traces back to at least one of them.
| Element | What it covers | The question it answers |
|---|---|---|
| Strategy | Direction, priorities, the plan for the next 90 days, what you say no to | Are we working on the right things? |
| Accountability | Weekly numbers, commitments made and kept, someone outside the business checking | Did we do what we said we would? |
| Mindset | The owner’s thinking: decisions, confidence, the habits that set the ceiling | Is the owner the constraint? |
| Systems | Processes, delegation, a business that runs without the owner in every room | Does everything depend on you? |
The elements are deliberately plain. There is no jargon to memorise and no certification to buy. The value is in applying them consistently, against real numbers, with someone holding you to it. Nick coaches in the morning and applies the same advice to his own businesses in the afternoon, which keeps the framework honest.
Was CoreOS always four elements?
No, and this is worth clearing up. CoreOS was originally taught as eight principles. Those principles have since been grouped into the four elements above, because four things are easier to hold in your head than eight, and easier to act on under pressure. Nothing was removed. If you have read an older description of CoreOS that lists eight principles, it is the same framework, reorganised. The current version is set out in full in the CoreOS framework post on the blog.
How is CoreOS applied in Momentum and the Cabal?
CoreOS is applied through two programmes: Momentum, a one-to-one coaching partnership, and the Cabal, a 12-month mastermind. Both are application only.
| Momentum | The Cabal | |
|---|---|---|
| Format | Monthly one-to-one coaching partnership | 12-month mastermind with capped numbers |
| Rhythm | Monthly strategy session, accountability between sessions, direct access when something urgent lands | Three in-person Cabal Days a year, monthly calls, weekly accountability, quarterly one-to-one Power Coaching, hot seats |
| Best for | Established owner-led businesses already trading, usually with a team | Owners who want peers in the room as well as coaching |
| Entry | Apply for a 30-minute call, no charge, reply in one working day | By application; it is for trading businesses, so pre-revenue owners should wait |
In both programmes the four elements set the agenda. Strategy work happens in the sessions. Accountability runs between them. Mindset gets addressed when it is the real blocker, which it often is. Systems work turns each fix into something permanent, so the same problem does not come back in six months wearing a different hat.
How do you score your business against CoreOS?
You score it with the free CoreOS Scorecard, which measures your business against the four elements. It works like this:
- Answer 12 tap-through questions about how your business runs today.
- Get an instant score and a radar showing where you are strong and where you are exposed across the four elements.
- Answer a set of optional deeper questions if you want more detail.
- Get an AI-generated 12-month plan built from your answers.
It costs nothing and there is no sales call attached. You can take the Scorecard here. Most owners find the radar confirms something they already suspected and had not said out loud.
Who is CoreOS for?
CoreOS is built for owner-operators of established UK businesses, typically turning over roughly £200k to £2m, where the owner is still central to how the business runs day to day. That is the person the framework was designed around, because that is the position Nick has been in himself.
It is just as important to say who it does not suit. If you are pre-revenue, you need customers before you need an operating framework. If you want a cheerleader, or theory for its own sake, Core will frustrate you. The framework assumes you want straight answers and are prepared to act on them.
If you want to see where your own business stands against the four elements, the Scorecard is the place to start.
