Koldconvert Fractional CFO gives high-growth companies access to experienced financial leadership at the right cost for their stage. We build the financial infrastructure, models and investor-ready reporting that founders need without the salary, equity and overhead of a full-time CFO. Whether you are preparing for a raise, scaling quickly through a new market or building the financial discipline needed for Series A due diligence, we provide the financial command layer your business requires to grow with control.
What is a fractional CFO?
A fractional CFO is an experienced chief financial officer who works for a company on a part-time, retainer or project basis rather than as a full-time employee. They provide the full range of strategic finance capability — financial modelling, scenario planning, unit economics design, fundraise preparation, investor relations, board reporting and cash flow management — at a fraction of the total cost of a full-time CFO hire. Fractional CFOs are typically engaged by high-growth companies at Seed to Series B stage who need senior financial leadership but do not yet have the scale or budget to justify a full-time hire, or by companies at a specific strategic inflection point such as a fundraising round, an acquisition or a rapid market expansion.
What Your Fractional CFO Covers
Financial Modelling
Three-statement financial model (P&L, balance sheet, cash flow) with integrated revenue drivers, scenario planning and sensitivity analysis. Built to run the business and to share with investors.
Fundraise Preparation
Investor-ready financial model, data room build, key metric preparation, due diligence Q&A support and coaching for financial questions during investor meetings.
Unit Economics
CAC, LTV, payback period, gross margin per cohort and contribution margin analysis. The unit economic foundation that tells investors whether the business model works at scale.
Board and Investor Reporting
Monthly management accounts, board pack preparation and investor update templates. Consistent financial reporting that builds credibility with your board and existing investors.
Signs You Need a Fractional CFO
- You are preparing for a Series A, B or growth round and do not have a financial model that can withstand investor scrutiny or answer due diligence questions.
- The CEO or COO is spending 20% or more of their time on financial management, reporting and investor questions that a CFO should own.
- You know your revenue and burn rate but cannot confidently answer what your unit economics look like across different customer segments or channels.
- Board meetings involve spending the first 20 minutes reconciling different versions of financial data from different team members.
- You are heading toward an audit, acquisition or a significant contract that requires investor-grade financial records and you do not have them.
From Finance Audit to Strategic Financial Leadership
Finance Audit
Audit current financial infrastructure, reporting quality, existing models and the key financial decisions leadership needs to make with greater confidence and accuracy.
Financial Foundation
Build or rebuild the financial model, define unit economics, establish consistent metric definitions and set up management accounts that reflect how the business actually operates.
Strategic Finance
Lead financial planning and analysis, build board reporting packs, prepare investor materials and provide direct support for fundraise and due diligence processes.
Ongoing Advisory
Monthly financial review, board meeting attendance, investor reporting and continuous model updates as growth, pricing and product evolve.
The Koldconvert Financial Command System
The Koldconvert Financial Command System is built on the belief that finance at a high-growth company should be a strategic function, not a reporting function. Most companies at Seed to Series B stage have someone managing bookkeeping and preparing VAT returns. What they lack is a financial leader who can translate the numbers into strategic decisions: where to deploy the next pound of capital, which channels have the lowest CAC payback, which pricing change improves LTV without destroying conversion rate. We build the financial infrastructure, define the metrics that matter for your business model, and sit alongside leadership to apply financial rigour to every significant decision. The goal is a company that can articulate its unit economics and financial trajectory with confidence to any investor, board member or acquirer at any point in time.
Founders at the pre-Series A stage often believe they cannot afford a CFO. The reality is they cannot afford not to have one. The financial decisions made between Seed and Series A, including when to burn faster, what to charge for the product, which cohort of customers has acceptable unit economics and how much runway you actually have, are among the highest-stakes decisions a company makes. Getting them wrong with bad data is more expensive than a fractional CFO engagement. The question is not whether you can afford financial leadership; it is whether you are making million-pound decisions with the financial clarity those decisions deserve.

Fractional CFO services, answered
A fractional CFO is an experienced chief financial officer who works for a company on a part-time or project basis rather than as a full-time employee. They provide the same strategic finance capability — financial modelling, fundraise support, board reporting, unit economics — at a fraction of the cost of a full-time CFO hire.
Most companies need a fractional CFO when they are preparing for a fundraising round, experiencing rapid growth that creates financial complexity, preparing for an audit or due diligence process, or when the CEO is spending more than 20% of their time on finance and needs to delegate that function.
A bookkeeper records historical transactions. An accountant prepares financial statements and handles compliance. A fractional CFO operates at the strategic level: financial planning and analysis, fundraise preparation, investor relations, unit economics design and board-level financial communication. These are distinct roles with minimal overlap.
Fractional CFO services typically cost 60-80% less than a full-time CFO hire when comparing total compensation, benefits, equity and overhead. Engagement structures vary from a fixed monthly retainer to project-based arrangements for specific events like a fundraise or data room build.
Yes. Fundraise preparation is one of the highest-value applications for a fractional CFO. They build the financial model, prepare the data room, define and stress-test the key metrics investors will interrogate, and coach the CEO on financial questions during investor meetings.

Strategic Finance Glossary
- ARR (Annual Recurring Revenue)
- ARR is the annualised value of all active recurring subscriptions or contracts, used as the primary revenue metric for subscription businesses. It normalises revenue to a 12-month value regardless of billing frequency and is the metric most investors use to assess the scale and trajectory of a SaaS business.
- CAC Payback Period
- CAC payback period is the number of months a company needs to recover the cost of acquiring a customer from that customer's gross margin contribution. A payback period under 12 months signals capital-efficient growth. Longer payback periods increase funding requirements and indicate the business needs either lower CAC or higher margin per customer.
- Burn Rate
- Burn rate is the monthly net cash outflow of a company above revenue received. Gross burn refers to total monthly spend. Net burn subtracts revenue. Runway is calculated by dividing current cash balance by monthly net burn rate, indicating how many months the company can operate without additional funding.
- Unit Economics
- Unit economics describes the direct revenue and costs associated with a single unit of business, typically one customer. For SaaS companies, strong unit economics means LTV is at least three times CAC and the payback period is under 18 months. Unit economics determine whether a business model is sustainable at scale independent of growth rate.
- Data Room
- A data room is a secure, organised repository of documents and data shared with prospective investors during due diligence. A strong data room includes the financial model, cap table, management accounts, customer contracts, key metric analysis, legal documents and employment records, structured so investors can complete diligence efficiently.
- NRR (Net Revenue Retention)
- NRR measures how much of the revenue from an existing customer cohort is retained and grown over a period, after accounting for expansion, contraction and churn. NRR above 120% is considered best-in-class for SaaS and means the existing customer base grows revenue organically without requiring new logo acquisition.
