Most scaling businesses reach a point where the founder is making seven-figure decisions on instinct, and the numbers can no longer keep up. You do not yet need a full-time CFO, but you have outgrown bookkeeping and spreadsheets. That gap is where Momentum CFOs lives.
We are a specialist Fractional CFO firm supporting ambitious UK startups, scale-ups, and investor-backed businesses. What sets us apart is simple: you are not hiring a lone consultant, and you are not paying a recruiter to place a contractor. You get a dedicated Fractional CFO embedded in your business, backed by an entire Office of the CFO: the systems, financial models, reporting frameworks, fundraising expertise, and wider team that sit behind them.
That means institutional knowledge rather than one person's habits, proven operating models rather than reinvention every time, and far less key-person dependency. Your CFO leads the engagement day to day, but is never on their own. When a specialist skill is needed, it is already in the building.
Across our CFOs our clients gain the benefit of a track record that includes £900m in M&A deals, £600m of fundraising, financial control of businesses ranging from £1m to £400m in turnover, leading finance teams, starting finance teams, and implementing turn arounds.
A bootstrapped business and a PE-backed one face completely different problems, so we do not treat them the same. We match the right CFO, the right framework, and the right priorities to where you actually are.
If you are bootstrapped, the work is cash discipline and unit economics: the numbers that decide survival. From seed to Series A, it is the rush of firsts, your first board, your first raise, and your first forecast that has to stand up to scrutiny. Through Series A and beyond, the job is professionalising the finance function so it keeps pace with growth. And once you are PE-backed, reporting rigour and value creation move to the front.
And when the goal is a sale, we prepare the business for exit: clean numbers, a defensible valuation, and a financial story that holds up under a buyer's scrutiny, so you realise the value you have built.
Good businesses understand cause and effect. Most early finance functions only describe the past. We build driver-based financial models that answer the question that actually matters: if we change X, what happens to Y? Hiring, marketing spend, pricing, the timing of a raise: we model the consequences before you commit, so you make the call with clarity instead of crossing your fingers. The output is not a prettier report. It is better decisions, made with confidence and visibility.
We have been through these journeys many times, across venture capital, private equity, and debt. We build investor-ready models, prepare the materials and data room, and shape the financial narrative that ties a round together, then stay close through diligence. This is practical experience from real raises, not theory.
We work with founders and leadership teams across a broad range of sectors, including deep-tech and climate technology, agtech, B2B SaaS, consumer brands, engineering, and asset-backed ventures. The common thread is ambition: businesses scaling fast enough that finance has become too important to leave to chance.
As part of the HSBC Innovation Banking rewards programme, we are offering exclusive terms to fellow clients, because these are exactly the businesses we are built to serve.
You already know what a good finance function is worth. The question is who to trust with it? Most founders are choosing between three bad options: stay on instinct and patchy spreadsheets, hire a full-time CFO you cannot yet justify, or take a punt on a solo contractor and hope they are the right one. We built Momentum CFOs to be the option that actually fits a scaling, investor-backed business.
A solo fractional CFO gives you one person's knowledge, one person's bandwidth, and one person's blind spots. A recruiter just hands you a contractor and walks away. With us, a dedicated Fractional CFO leads your engagement day to day, but is never working alone. They are backed by the full Office of the CFO: our models, reporting frameworks, fundraising playbooks, and the combined experience of the wider team. When your situation needs a specialist, whether that is a complex raise, a cross-border structure, or an exit, the expertise is already in the building. You carry far less key-person risk, and you never outgrow the person in the room.
The realities of seed are nothing like Series B, and a business heading for sale needs something different again. So we start by understanding where you are and where you are going, then put the right CFO in front of you: the one whose experience fits your stage, sector, and the decisions coming down the line. The match is deliberate and personal, because the relationship is the product.
Founders do not lie awake worrying about month-end. They worry about the real questions. Can we afford this hire? How much should we raise, and when? Is that new channel actually working, or just busy? Most finance functions answer with a backward-looking report. We answer with driver-based models that show cause and effect: change this input, and here is what happens to runway, to margin, to the raise. You walk into the board meeting or the investor room knowing your numbers cold, with the narrative to match. Every report we produce ties back to a decision you have to make.
This is where experience stops being a buzzword. Across our CFOs our clients gain the benefit of a track record that includes £900m in M&A deals, £600m of fundraising, financial control of businesses ranging from £1m to £400m in turnover, leading finance teams, starting finance teams, and implementing turn arounds. Add 25 years of group finance leadership across regulated, high-volume, and international environments, and FCCA and ACMA qualifications behind the work. We have sat on your side of the table through the raises, the board fights, and the exits. We know what is coming next, because we have been there.
You do not have months to wait for someone to find their feet. Within weeks of starting, you will have a clear cash and KPI baseline, a model that reflects how your business actually works, and the sense that a senior finance partner is genuinely part of the team. Whether the trigger is a raise that has to close, a board that needs convincing, a runway date on the horizon, or a buyer at the door, we get you ready in time, not after the fact.
We speak founder, not jargon. We are direct about what the numbers say, decisive about what to do next, and we prioritise so nothing important slips. No corporate consulting theatre, no decks for the sake of decks. Just senior people who have solved these problems before, helping you make better calls with confidence.
It starts with a conversation. You book a call, meet your proposed Fractional CFO, and we visit you on site (where it helps). From there we agree a clear, simple engagement, a retainer, a model build, or fundraising support, with no surprises on scope or cost. We are a premium service and we are not the right fit for everyone, so we would rather be straight with you up front than sell you something you do not need.
As fellow members of the HSBC Innovation Banking community, we are offering exclusive terms to clients on the programme. If you are scaling fast enough that finance has become too important to leave to chance, this is exactly the moment to talk.
