Building the Forecasting Infrastructure That Secured Investment
How do you build a financial model that can withstand investor scrutiny? A case study in turning raw numbers into a compelling, defensible investment case.
A SaaS Founder Ready to Raise — But the Model Wasn't Ready
The Situation
The client was a SaaS founder who had been trading for a few years and was preparing to raise. They had established revenue with new products in the pipeline — but the financial model wasn't investor-ready. The numbers existed; they just couldn't tell a clear story.
What Was Missing
No structured revenue forecast
Costs not aligned to how the business would actually scale
No narrative connecting historical performance to the forward-looking plan
What Investors Need to See
Investors need to see that you understand your own business. That means a model where every assumption can be explained, every growth driver is grounded in evidence, and the path from today's numbers to tomorrow's targets is credible.
Explainable Assumptions
Every number has a rationale that can be defended under pressure.
Evidence-Based Drivers
Growth projections grounded in historical performance, not wishful thinking.
Credible Path Forward
A clear, logical bridge from current results to future targets.
The Approach
Rebuilding the Financial Model From the Ground Up
Four interconnected workstreams — each designed to make the model more credible, more defensible, and more compelling to investors.
1
Revenue Forecast
Key growth drivers identified, targets set for the financial year. Every assumption backed by historical performance — no hockey-stick projections without evidence.
2
Cost of Sales
Gross margin drivers reviewed to reflect what would actually happen as revenue grew. A cushion built in where costs were harder to predict.
3
Vendor Audit
Every software cost and subscription reviewed for redundancies and unused licences. Spend not generating clear value was flagged and addressed.
4
Headcount Plan
Restructured around profitability. Every new hire tied to a specific milestone — efficient, milestone-driven growth, not premature scaling.
Deep Dive
Revenue Forecast: Evidence-Led, Not Aspirational
The Approach
We reviewed the existing revenue model and identified the key growth drivers that had actually moved the needle historically. Targets for the financial year were set based on what the business had already demonstrated it could achieve. We didn't project hockey-stick growth without evidence — we showed what was realistic based on what the business had already proven.
Why This Matters in Due Diligence
Investors will stress-test every assumption. A forecast built on historical evidence doesn't just look credible — it is credible. When challenged, the founder could point to the data behind every number.
This transforms the fundraising conversation from defending projections to explaining a well-reasoned plan.
Deep Dive
Cost Structure, Vendor Audit & Headcount
Cost of Sales Aligned to Growth
Gross margin drivers were reviewed to ensure they reflected what would actually happen as revenue scaled. Where costs were harder to predict, a cushion was built in — better to under-promise and over-deliver than to present margins that fall apart in due diligence.
Full Vendor Audit
Every software cost and subscription was reviewed for redundancies and unused licences. Spend like online ads not generating leads or clear value was flagged. This showed investors that every pound of spend was intentional.
Headcount Restructured Around Profitability
Tough calls were made on roles that needed to change or go. Where hiring was planned, each new role was tied to a specific milestone — demonstrating efficient, milestone-driven growth rather than scaling before the proof was there.

Who This Is For
Is This Engagement Right for You?
This engagement is designed for SaaS founders at a specific stage of growth who are preparing to go to market for investment.
Stage
SaaS founders between £0.5M and £10M ARR preparing for a seed or Series A round.
Your Numbers Need Work
You know your numbers need to be stronger before going to market and want to fix that before investor conversations begin.
Investor Feedback
You've had investor feedback that your model isn't detailed enough and need a qualified partner to help address it.
Finance Partner
You want a qualified finance partner alongside you during the fundraise — someone who knows what investors will ask.
Preparing for a raise is one of the most common reasons SaaS founders bring in a fractional CFO. Having someone who has done this before — who knows what investors will ask and how the numbers need to be presented — makes a material difference to the outcome.
From Messy Numbers to Investor-Ready Model
A structured engagement that takes your existing financial data and transforms it into a model that can withstand the rigour of investor due diligence — with every assumption grounded in evidence.
Pattern Recognition
Having seen multiple fundraises, a fractional CFO knows the questions investors ask and the red flags they look for.
Credibility in the Room
A qualified finance partner alongside you signals to investors that the numbers have been properly scrutinised.
Speed to Market
Rather than iterating on your model through investor feedback, arrive investor-ready from the very first conversation.
