Fractional CFO · AI Companies

AI finance is different.
Your CFO should be too.

Standard SaaS finance doesn’t map cleanly onto AI businesses. GPU costs, inference economics, model training spend, and usage-based pricing require a CFO who understands the stack — not just the spreadsheet.

The AI Finance Challenge

What makes AI company finance hard.

The questions investors ask AI companies are different. Standard CFO playbooks don’t have the answers.

GPU & Compute Costs

Training runs, inference costs and cloud commitments can dominate your P&L. Most finance teams don’t know how to model them — or when to commit to reserved capacity.

Inference Economics

Cost-per-token, cost-per-call, and gross margin per customer vary wildly by usage pattern. Getting this wrong makes your unit economics look better than they are — until an investor digs in.

Usage-Based Pricing

Token-based, API call-based, and consumption pricing require a completely different revenue model to subscription SaaS. Revenue recognition, forecasting and cohort analysis all change.

R&D vs Capex Classification

Model training costs, fine-tuning, and dataset acquisition sit in a grey zone between R&D expense and capitalised development costs. Getting this right matters for EBITDA and tax.

Investor Scrutiny

AI investors are increasingly sophisticated. They’ll ask about gross margin by customer, inference cost trajectory, and your path to positive contribution margin. You need answers ready.

Regulatory & Compliance Cost

EU AI Act compliance, safety testing, and model evaluation requirements are emerging cost lines. Planning for them now avoids surprises in your Series A or B financial model.

Our AI CFO Service

CFO thinking built for the AI era.

GPU Cost Modelling

We model your compute costs dynamically — training vs inference, reserved vs on-demand, cost-per-token by model size. Linked into your P&L so the impact is always visible.

AI Unit Economics

Gross margin per customer, cost-per-query, and contribution margin analysis. Built so you can show investors a credible path to scale economics.

Investor-Grade Financial Model

3-statement model with AI-specific COGS build, usage-based revenue modelling, and scenario analysis built for Seed through Series B investor scrutiny.

Fundraise Support

Data room build, investor Q&A preparation, and term sheet review. We’ve supported AI companies raising from £500k SEIS rounds to £15m+ Series A.

Ongoing Monthly CFO

Board pack, metrics dashboard, actuals vs plan review, and cash management. A senior CFO in the room every month — at a fraction of the cost of a full-time hire.

Who This Is For

AI companies at every stage.

Seed & Pre-Seed

Building the foundation

You’re pre-revenue or early-stage, burning through cloud credits and building your first product. You need a financial model that tells a compelling story for investors — and a CFO who can talk compute costs fluently.

Pre-seed / SEIS financial model

Compute cost baseline

Runway management

Series A

Scaling with rigour

You have early revenue and you’re raising to accelerate. Investors are now scrutinising your unit economics, gross margin trajectory, and whether your inference costs will improve at scale. You need a CFO who can defend the numbers.

Series B & Beyond

Finance as a competitive edge

You’re scaling fast and the financial complexity is growing. Multi-product revenue, international operations, reserved instance commitments, and a board that needs quarterly rigour. You need a partner-level CFO without the £200k+ salary.

FAQ

Common questions.

Both. Many of our clients are traditional SaaS businesses that have started embedding AI into their product and are finding that their compute costs are now material. If AI is becoming a meaningful cost line in your P&L — whether you’re an AI-first company or a SaaS business integrating LLMs — this service is relevant to you.

Enough to build the right financial models — which is what matters. We understand the difference between training and inference costs, how to model token-based pricing, the economics of reserved vs on-demand GPU capacity, and how model size affects your cost structure. You don’t need us to understand transformer architectures; you need us to model their financial implications correctly.

Pre-revenue AI companies are common clients. At this stage, the financial model is built around your hypothesis: target customer, assumed usage patterns, pricing model, COGS assumptions, and the funding required to reach the next milestone. The model tells the story investors need to see even before revenue exists.

Monthly board pack (P&L, cash flow, KPI dashboard), actuals vs plan variance analysis, cash and runway management, compute cost review, and strategic CFO input as needed. We attend board calls where required. The service scales with your needs — it’s not a fixed template.

Project work (financial model, fundraising package) is priced on a fixed-fee basis, agreed before we start — typically from £3,500+VAT for a standalone model. Monthly ongoing CFO retainers start from £2,500/month+VAT depending on scope. We’ll agree the fee upfront with no surprises.
