Dermot Campbell — Fractional finance and operating leadership

Finance and operating leadership for companies that are scaling.

Fractional CFO and COO support for founder-led and investor-backed businesses: senior capacity that actually delivers, not advice from the sidelines, working alongside the CEO on the numbers, the execution and the governance beneath both.

The same disciplined finance mind, whether you need it pointed at the finance function or at operations. Available fractionally, on a defined project, or in a full-time role.

One discipline, two ways in.

Underneath both roles is the same thing: a rigorous, evidence-led way of thinking applied to whichever part of the business is under most pressure, and the capacity to act on it rather than just diagnose it. Governance is built into both, not sold as an extra.

Fractional CFO

The finance function

Senior ownership of the finance function, so the business stops lurching from one cashflow crisis to the next and gets a clear read on which numbers actually drive it. Fractionally where a full-time CFO is more than the stage needs, or permanently where it is not.

Budgets, forecasting and rolling cashflow against burn
Management accounts, board packs and investor reporting
Fundraising support, valuation and capital allocation
Financial modelling and business planning
Financial controls, risk and regulated-sector discipline

Fractional COO

Operations and execution

Senior operating capacity that picks up real project and delivery work: turning strategy into priorities, coordinating work that has no clear owner, and building the rhythm that keeps delivery moving. Not facilitation from the sidelines.

Cross-functional priorities across product, sales and operations
Leadership rhythm, decision rights and accountability
Customer discovery, product focus and go-to-market clarity
Commercial execution and client-service discipline
Where it helps, AI and workflow automation to remove manual drag

Governance is not a separate line of work. It is the decision rights, delegation and reporting rhythm that let a business run itself properly: who decides what, how information reaches the people who need it, how progress gets tracked. Done well it is not compliance for its own sake but the fabric that underpins good leadership, and it is built into the CFO and COO work rather than added on top. Where a company wants that judgement from outside the executive, I also take independent chair, non-executive and board-adviser roles.

These are growth signals, not problems.

We need finance run properly, but a full-time CFO is more than the stage justifies.

The board and investors need cashflow, forecasting and reporting they can actually rely on.

We have outgrown informal founder-led ways of working and need clearer ownership and rhythm.

We know what needs to happen, but nobody has the bandwidth or objectivity to run delivery.

Sales conversations are not landing, and we need sharper customer pain and route to market.

The business is becoming more complex. That is what success looks like, and it is the point at which finance, execution and decision-making need experienced support to keep moving.

Grounded in the realities of building and running organisations.

I have founded and led three ventures, owning the finance function in each with no separate CFO, and raised over £3m across them from angels and VCs. Kuber Ventures, an investment platform serving wealth managers and advisers, which I took from an Excel model to a full online platform and built the team around it. Board Originator, a governance SaaS business built around board workflows, investor reporting and management systems. Augentic, working on how AI agents could carry routine governance work while leaving judgement with people.

Before that, seven years in senior roles at UBS Wealth Management, latterly as a director leading a team serving professional intermediaries, with responsibility for around £500m of client assets, substantial collateralised lending exposure, and a restructuring that halved headcount while improving returns.

Alongside, I have been treasurer and a trustee of a public-interest organisation, taking it through charitable conversion and a finance-function rebuild that started with reconstructing the accounts from raw records. And I advise a smaller listed company on governance reform, board effectiveness and reporting cadence.

Earlier still, I flew commercially. It taught me more about structured decision-making under pressure than anything since.

Most of this work has been in founder-led and growth-stage businesses, because that is where the need is greatest. The discipline does not change with size: the same structure, decision rights and financial rigour that keep a small team running well are what keep a larger one running well too, which is what the UBS desk and the listed-company advisory work drew on at a materially bigger scale.

Start with a conversation.

The first step is a short, no-obligation conversation about where the business is under pressure.

We work out whether there is a clear value case and, if there is, define a focused first piece of work. If there is not, I will tell you. Email is the surest way to reach me, and I answer personally.
