Fractional CFO for pre-seed startups

At pre-seed the company is still mostly a thesis - early product, first paying users, founders running on conviction and a small angel cheque. The financial questions that matter are not bookkeeping; they are how big the opportunity actually is, what a credible 24-month plan looks like, and how much money the team needs to prove the next milestone.

We work alongside the founders to translate the vision into numbers - a clean operating model, a first pass at unit economics, a runway view tied to the milestones that unlock the seed round. Light-touch on process, heavy on strategic input, so founders spend their time on product and customers rather than on a spreadsheet they don't trust.

Why pre-seed startups need a fractional CFO

Hiring a full-time CFO is a huge (and costly!) decision, and most advisors stuck in the 90s do not understand how a pre-seed-stage business actually runs. We deliver actionable, no-BS advice tailored to your stage and the digital niche you operate in.

Translate the vision into a model investors believe

Pre-seed pitches live or die on whether the numbers behind the deck hold up. We build a simple bottoms-up model that connects market size, acquisition cost, conversion and pricing into a 24-month plan - defensible enough that angels and pre-seed funds will engage on substance rather than walk away on credibility.

Lock in unit economics from day one

Most pre-seed companies cannot yet prove unit economics - but they need to be precise about which ones they are betting on. We define CAC, payback, gross margin and contribution margin on day one, so every product, pricing and channel decision over the next 18 months is measured against the same yardstick.

A short list of KPIs the company actually runs on

At pre-seed every team is drowning in vanity metrics. We cut the list down to the three or four numbers that genuinely move the business - activation, retention, ARPU, week-on-week growth - and put them in front of the founders weekly, so attention flows to where the company is winning or losing.

Burn discipline before it becomes a survival problem

Pre-seed runway looks long until you accidentally over-hire. We track cash weekly, model the next hire before the offer goes out, and call out spend that does not move a milestone - so the runway you sold to angels is the runway you actually have when it is time to raise the seed.

Be the strategic finance partner founders can call

Founders at this stage need someone to pressure-test a SAFE term, a pricing change, a hiring decision or a partnership before they sign it - not a quarterly call once the deed is done. We are embedded enough to be the first call, and senior enough that the answer is grounded in what actually happens at seed and Series A.

Set the company up so the seed round is a continuation, not a restart

Seed funds will diligence the same three things every time: market, traction, and a credible plan. We make sure the financial story, the operating model and the KPI dashboard are already in a shape that a seed VC will recognise - so when the round opens, the team is presenting, not scrambling to assemble.

Different growth phase?

We provide fractional CFO services across pre-seed, seed, Series A, growth-stage and PE-backed companies.

Fractional CFO for seed-stage startups

At seed we build the driver-based operating model, stand up the monthly FP&A cycle, put cohort and unit-economics tracking in place, and prepare the company for Series A diligence well ahead of the raise.

Fractional CFO for Series A startups

At Series A we build the institutional-grade model, segment the P&L for capital allocation, run the board-pack rhythm with proper variance analysis, and prepare the company for Series B at least 12 months ahead of the raise.

Fractional CFO for growth-stage startups

At growth stage we run segment-level FP&A across multiple entities, scale planning beyond spreadsheets, manage debt and treasury actively, and keep the company optionality-ready for Series C, growth equity or strategic M&A.

Fractional CFO for PE-backed companies

For PE-backed companies we own the value-creation plan and sponsor reporting, drive EBITDA quality and cash conversion, manage debt actively, run bolt-on M&A end-to-end, and keep the company exit-ready throughout the hold period.
