Fractional Chief Strategy Officer

Every owner needs one person
with nothing to defend.

A part-time strategy director for founders and owner-managers. Close enough to the business to be useful, far enough from it to be honest. Not a bench of consultants and not a permanent hire. One person, the same one, on the decisions that carry real risk.

Also called a fractional CSO, a part-time chief strategy officer, or simply the person a founder calls before making the decision.

Start with a diagnostic → Is this you?

The relationship

One strategy lead, retained. Not a rotating team and not a stack of CVs.

The entry point

A diagnostic first. Nothing is scoped or signed before the problem is named.

The commitment

Mutual. We agree a timeframe together, and we agree together when it has run its course.

01, The Seat You Sit In

48%

of chief executives spend less than one day a month on strategy.

It is not that the thinking is wrong. It is that there is no time to do it.

The work that decides where the business goes in three years is the work that gets moved for the thing that is on fire today. Every owner knows it is happening and cannot stop it happening.

Underneath that sits a second problem. Almost everyone qualified to help has a position. Your leadership team built the current plan and disagreeing with you has a cost for them. Your board sees a version of the business that was assembled for the board. So the calls that carry the most risk get made on the thinnest evidence, usually at pace, usually alone.

"Everyone in the room agreed, and I still did not feel confident."

"I have three versions of the same number and a board meeting on Thursday."

"I know this is the wrong answer. I do not know what the right question is."

02, The Missing Seat

Every other seat owns a slice. One seat owns where you are going.

A tech founder builds the executive team in the order the pain arrives. A CTO because the product has to ship. A sales lead because revenue has to close. Marketing because nobody has heard of you. Someone in operations once the machine starts grinding, and someone in people once the headcount outgrows a spreadsheet.

Every one of those roles is measured on its own slice, and rightly so. The CTO defends the roadmap. The sales lead defends the number. The COO defends the cost line. None of them is wrong, and none of them owns the question of whether the slices still add up to a business worth building.

That question belongs to the strategy seat, and in almost every growing company it is empty. The founder fills it themselves, in the evenings, between the things that could not wait.

A fractional CSO fills that chair for one, two or three days a month. Long enough to own the question. Not so long that you are funding a permanent executive to ask it.

03, Two Expensive Mistakes

Neither of these is a failure of intelligence. Both are expensive.

These are the two patterns that come up most often in first conversations with founders and owner-managers. They are rarely spoken about openly, because both of them feel like an admission. They are not. They are structural, and they are common enough to be predictable.

Mistake one

Hiring seniority at a specialist problem

When something important is going wrong, the instinct is to hire seniority at it. A director, a head of, a title that matches the size of the worry. It feels decisive, and it is frequently the wrong move.

Seniority is not the same as subject expertise. A capable senior hire will spend their first two quarters learning the specific problem you needed solved on day one, and you carry a permanent salary while they learn it. If the problem then turns out to be narrower than the role, you are left with an expensive person and a job that does not fill their week.

A senior hire is the right answer when you need somebody to run a function for years. It is the wrong answer when what you actually need is somebody who has already solved this exact problem, and who can be gone once it is solved.

Mistake two

Founder's syndrome

It is a real pattern and it has a name. The judgement that built the business slowly becomes the constraint the business cannot grow past. Every decision of consequence routes back through you, the team learns to wait rather than decide, and the more capable you are the more completely it happens.

From the inside it rarely looks like control. It looks like standards. It looks like nobody else understanding the business quite well enough to be trusted with it, which is usually true, because they were never given the chance to learn.

The cost is not a bruised ego. It is a business whose ceiling is one person's diary, and a leadership team that gradually stops bringing you their best thinking.

If this sounds like you

You are not alone, and it is not a character flaw.

Both patterns are the predictable cost of the thing that got you here. Conviction and a refusal to delegate the important call are exactly what a business needs in its first years, and exactly what starts to hold it back later.

Neither is fixed by advice. They are fixed by putting the right expertise on the right problem for the right length of time, and by moving a handful of decisions out of your head into a structure that can hold them. That is the work, and there is a way through it.

04, Is This You

Six signals. Two of them and it is worth a conversation.

These are the patterns that show up before a business admits it has a strategy problem rather than a busy quarter. None of them is fatal on its own. Together they compound quietly.

01

Planning takes weeks and still produces a forecast that misses by a wide margin, quarter after quarter.

02

Three or more big initiatives are running, and fewer than half of them are earning their place.

03

A handful of customers or one product carries most of the revenue, and there is no plan to change that.

04

Margins are moving the wrong way and the explanation changes depending on who you ask.

05

You are losing bids you would previously have been shortlisted for, and nobody can say precisely why.

06

An investor asks a straight question and gets two different answers from your own team on the same call.

05, How It Starts

It starts with a diagnostic, not a proposal.

Before anything is scoped or signed, we do one short, defined piece of work: establishing what the problem actually is. Not the symptom you can see, the thing underneath it that keeps producing the symptom.

You end up with a written diagnosis. If it tells you what you needed to know and you take it away and run it yourself, that is a good outcome and there is no obligation on either side to continue.

01

The problem, restated

Your problem written in a form you can act on, with the evidence that supports it separated from the parts that are still assumption. Most engagements go wrong here, before any work begins.

02

What it is costing you

The cost of leaving it alone, in money and in time, with a range rather than a single confident number. Enough to tell you whether this is worth solving at all.

03

The first move

What I would do first, who owns it, and by when. Specific enough that somebody could start on Monday without another meeting to interpret it.

06, Then, Whichever Shape Fits

The diagnostic decides the shape.

Three ways this usually continues. Which one is right is a conclusion of the diagnostic, not a choice you have to make before you have the facts.

Retained days

An agreed number of days a month, held in the diary. Best when there is a programme of work and you want one head across all of it.

Ongoing, reviewed together

Fixed scope

One defined problem, an agreed scope, a timeline and an end date. Best when the diagnostic finds something specific and solvable, and what you need is for it to be finished.

Defined start and finish

A standing seat

A call a week, plus deep work when something needs it. Best when the value is judgment on live decisions rather than a project with a deliverable at the end.

Weekly, light touch

What done looks like

Every engagement has an end condition, written down at the start.

Not a date on a calendar. A condition: the forecast holds within an agreed band, the reporting runs without me, the decision is made and funded. Advisory work that cannot say what finished looks like is how a three-month engagement becomes a three-year habit.

What I decide, and what I do not

Ambiguity about authority is the quiet killer of this kind of work, so it gets agreed in writing before the first session.

Typically: I own the planning rhythm and the shape of the analysis, and I chair the reviews where initiatives are continued or stopped. I recommend on capital and headcount; you decide. Nothing goes to your board or your investors without you seeing it first.

07, What Comes With The Seat

Where most of the value is

Problem diagnosis

Working out what is actually wrong. Most work starts from a problem statement that is really a symptom, and a perfectly executed answer to the wrong question is the most expensive thing a business can buy.

Where the decision gets tested

Financial analysis and modelling

Margin bridges, unit economics, forecasts built from the bottom up rather than from a market share aspiration, and models you can interrogate instead of admire. Every output shows its working.

Strategic options

Genuinely different routes, not three versions of the same one, each with what it sacrifices stated as plainly as what it gains.

Market analysis

Who buys, why they switch, what they will pay, and which part of the market is worth your attention. Sized from the customer up.

Operations and transformation

Turning the decision into a sequence people can actually run, with the dependencies in the right order and the resistance planned for.

08, Four Things You Can Hold Me To

You will always know what I am guessing.

Everything I give you separates what you told me, what follows from it, and what I am assuming because the data does not exist yet. You should never have to work out which is which, and you will always know exactly where your own knowledge sharpens the answer.

Every number arrives with a range.

A single confident figure built on an unverified input does more damage than no figure at all. You get the base case and you get to see what happens when the two assumptions that matter most turn out to be wrong.

Nothing ends without an owner and a date.

Advice that cannot be started on Monday morning is not finished. Every recommendation names who does it, what done looks like, and when. No document that needs a follow-up meeting to be understood.

I will tell you when you do not need me.

If the diagnostic finds a problem your own team is better placed to solve, that is what the document will say. The value of this seat depends entirely on you believing what comes out of it.

09, When This Is The Wrong Hire

Three situations where I would turn this down.

This model fails in predictable ways, and it usually fails for reasons that were visible before anybody signed anything.

If one of these describes your business, a strategy seat is not what you need next, and I would rather say that in the first conversation than four months into an engagement.

There is nobody to execute it

Strategy without capacity underneath it produces documents, not results. If the team is already at full stretch, the honest first move is capacity, not advice.

The problem is not a strategy problem

Plenty of things that present as strategy are a cash problem, a hiring problem, or one working relationship that has broken down. Naming that correctly is worth more than a plan.

The decision is not really being delegated

If the answer is already decided and what is wanted is support for it, you do not need this seat. That is a legitimate thing to want. It is not this.

Start Here

Bring me the decision you keep putting off.

One conversation, no commitment and nothing to sign. If a diagnostic is the right next step I will say so, and if it is not I will tell you that instead.
