Fractional CFO for digital infrastructure companies

Digital infrastructure businesses are split between two very different financial models in the same sector. Edge, CDN, network security and infrastructure SaaS run on usage growth, gross margin and retention; data centres, fibre and tower assets run on capacity, power, utilisation and long-duration capex.

Mixing those two on a single P&L without the right structure produces a board pack that no one trusts. A fractional CFO who understands both sides - the SaaS lens and the infrastructure lens - can build the right model for whichever side the business actually sits on, and keep the capital story consistent with it.

We have advised founders across edge cloud, networking software and data centre operations, and we bring the right financial language to each.

Choose a fractional CFO that understands digital infrastructure

Why choosing a CFO with strong understanding of digital infrastructure is so important for your startup.

Usage, margin, retention

Software-side digital infrastructure lives on consumption growth, gross margin per unit of compute or bandwidth, and net retention. We build the usage-based revenue and margin model that ties customer behaviour to the P&L, so pricing, packaging and capacity decisions are grounded in real economics.

Capacity and capex planning

Data centre and connectivity businesses live or die on utilisation, power, cooling and capex timing - and a slip on any of them moves returns by hundreds of basis points. We model capacity build-out against contracted demand, so capex commitments line up with revenue ramp.

Blended capital stack

Digital infrastructure rarely funds itself on equity alone - project finance, infrastructure debt, vendor financing and sometimes public markets sit alongside. We help shape the capital stack and the reporting that each lender and equity investor wants to see, so the round and the facility close in parallel rather than at odds.

Two buyer pools, one company

Software-side assets sell on ARR multiples to PE and strategics; data centre and connectivity assets sell on long-duration cash flow to infrastructure funds. We make sure the numbers and the equity story fit the right buyer, and that the business doesn't get priced on the wrong template.

Financial modelling for digital infrastructure startups

We work with digital infrastructure founders to build investor-ready, KPI-driven financial models.

We dive deep into your company and sector specifics, to build a custom-made financial model driven by operational KPIs, requiring a minimal learning curve and time spent on monthly updates.

Capacity & utilisation

Power, cooling and rack space modelled against contracted demand and ramp. Ties capex commitments to revenue arrival rather than to ambition.

Usage-based revenue

Consumption, bandwidth or compute revenue modelled by customer and product. Tells the team where pricing and packaging changes will land on the P&L before they ship.

Capex & build schedule

Data centre, fibre or tower build phased against funding draws, equipment lead times and energisation dates. Reflects the cash profile of a long-duration infrastructure project, not a SaaS opex line.

Blended capital stack

Equity, project finance, vendor financing and infrastructure debt modelled into one cost of capital. Lines the round and the facility up so they close in parallel rather than at odds.

Gross margin per unit

Margin per unit of compute, bandwidth or rack delivered, with COGS attribution made explicit. The view software-side infrastructure VCs underwrite when usage is the headline metric.

Net retention & expansion

Customer-level retention, contraction and expansion measured on consumption. Separates a growth story driven by existing accounts compounding from one that needs constant new logos to clear churn.
