Fractional CFO for SaaS Founders — Financial Infrastructure & AI Operations
Your investors want
financial rigour.
You need it yesterday.
I embed with SaaS founders to build the financial infrastructure and AI-powered operations that make your business fundable, scalable, and genuinely efficient — without the cost of a full-time CFO.
The SaaS founder challenges a fractional CFO solves
Your lead investor wants a board pack in 30 days. Meanwhile, your ops are duct-taped together in Notion. On top of that, your finance function is a spreadsheet and a prayer. You need CFO-level thinking — but you're not ready for a £150k+ hire.
"Our reporting is a mess and the board knows it"
You're producing numbers, but not the right ones. No MRR bridge, no cohort analysis, no burn multiple — just a P&L your CFO at your last company would wince at.
"We don't actually know our unit economics"
CAC payback, LTV:CAC, gross margin by cohort — you could define these terms. But if a Series B investor asked you to walk them through the numbers in real time, you'd be improvising.
"Our ops are killing us but no-one owns it"
Sales is in one tool. Finance is in another. Customer success is in a third. As a result, nothing talks to anything. You've built a team of 30 people running like a startup of five — because operationally, you still are.
"Everyone's talking about AI but we're doing nothing"
You know AI should be embedded in your workflows. You've seen what it can do. However, between running the business and managing investors, no-one has the time — or the technical depth — to actually make it happen.
"We're burning runway faster than expected"
Your next raise is 12–18 months out. Your current burn rate has you worried. Yet you're not certain whether cutting or investing is the right call — because you haven't modelled it properly.
"I need a CFO but can't justify the salary yet"
A great CFO costs £150–200k. That's a significant chunk of your headcount budget. Nevertheless, you need the expertise now — not in 18 months when you can afford it. You're stuck.
The window between closing a round and your next board meeting is shorter than you think. Every week without financial infrastructure is a week of credibility you won't get back. Find out how a fractional CFO engagement can close these gaps — fast.
Fractional CFO thinking, without the full-time cost
Working directly with your leadership team — typically 2–4 days per week — I cover finance, operations, and technology simultaneously. Not as an adviser. As a builder.
What makes this different is the combination: the financial rigour of a Chartered Accountant, the technical ability to actually build the systems and automations, and the coaching skills to bring your team along with you. In short, you get strategy and execution under one roof.
I build, not just advise
As a full-stack developer, I don't just design your financial systems and hand them to someone else to build. I build them. That means faster execution and no translation layer between strategy and implementation.
Founder-facing, investor-fluent
Having sat in board meetings and due diligence sessions from both sides of the table, I know what investors actually want to see — and how to present it in a way that builds confidence rather than raises questions.
AI is embedded, not an afterthought
As an AI Operations Lead, I bring genuine experience designing and shipping AI-powered workflows — not theoretical knowledge. Your team will work faster and your cost base will improve.

Not sure which fractional CFO service fits?
Most founders reach out on LinkedIn first. No pitch — just an honest conversation about where you are and whether I can help. You can also see how the process works or read the FAQs first.
How fractional CFO engagement works
Working with a fractional CFO should be simple. No long onboarding. No bureaucracy. From first conversation to first deliverable in under two weeks.
First conversation
Reach out on LinkedIn for a 30-minute conversation to understand your current financial position, what's blocking you, and what success looks like in 90 days. I'll be direct about whether and how I can help.
Scoping & proposal
Within 48 hours, I'll send a clear proposal: scope of work, time commitment, pricing, and what you can expect in the first 30 days. Nothing vague, no hidden surprises.
Embedded & building
I start with a finance and ops audit, then move fast. First deliverable within two weeks. Regular standups, a shared workspace, and full visibility on everything I'm working on.
Chartered Accountant (FCA) · ICF Coach
Nadia Hossen Mamode — Fractional CFO & AI Operations Lead
A Chartered Accountant with 15+ years of experience, I'm also a full-stack developer and an ICF-certified coach. Over the last several years, I've been embedded with Series A–C SaaS companies as both Fractional CFO and AI Operations Lead — which means I understand the financial, technical, and human dimensions of scaling a company simultaneously.
Before going fractional, I worked inside high-growth SaaS businesses where I built the financial infrastructure from the ground up: the models, the board packs, the data pipelines, and the AI workflows. As a result, I know what investor scrutiny feels like from the inside — and how to prepare for it properly.
Based in the UK, I work primarily with European and US-backed founders. To ensure genuine availability and accountability, I typically take on two to three clients at a time.

Connect on LinkedInWhat does "fractional" actually mean in practice?
It means I work with your company on a part-time, embedded basis — typically 2–4 days per week — rather than as a full-time hire. As a result, you get genuine availability (not just a monthly call), a shared Slack channel, and accountability for deliverables. The difference between a fractional CFO and a consultant is that I own outcomes, not just advice. In other words, I'm part of your team for as long as we work together.
How much does it cost?
Engagements are scoped individually based on the work required and time commitment. As a benchmark: most clients invest between £6,000 and £15,000 per month, depending on the scope and days-per-week commitment. For project-based work (e.g. fundraise preparation), I offer fixed-fee engagements instead. In all cases, pricing is agreed upfront with no surprises. The first conversation is free and carries no obligation.
About fractional CFO engagements
We've just closed a Series A. Is it too early for a fractional CFO?
Series A is actually the ideal moment. You've just taken on institutional capital, your investors have real expectations, and you're about to scale your team and spend — all without the financial infrastructure to manage it safely. Furthermore, the founders who wait until Series B spend the first six months of that process fixing problems that should have been addressed at Series A. Early engagement is therefore almost always more valuable than late-stage triage.
We already have a Finance Manager / Head of Finance. Do we still need you?
Yes, and this is actually a common setup. A Finance Manager handles day-to-day transactions, payroll, and compliance. A CFO — fractional or otherwise — handles strategy, investor relations, fundraise preparation, board reporting, and cross-functional financial decision-making. These are therefore complementary roles, not competing ones. In most cases, working with me makes your existing finance team significantly more effective because they have strategic direction and clearer priorities.
How long does a typical engagement last?
It varies by type. Ongoing fractional CFO engagements typically run for 6–24 months — often until a company is ready to hire a full-time CFO, or until we've built out the finance function to a point where it can run largely independently. By contrast, fundraise-specific engagements are typically 6–10 weeks. Meanwhile, AI Ops projects range from 4 to 12 weeks depending on scope. In all cases, I'll give you an honest view on what's realistic — and I won't artificially extend an engagement if the work is done.
