Fractional CFO for AI infrastructure & semiconductors companies

AI infrastructure and semiconductor businesses sit on long product cycles, heavy capex and concentrated customers, so the finance function carries balance-sheet weight that software CFOs never see. Tape-out cost, NRE, wafer commitments and capitalised R&D dominate the asset side. Revenue recognition has to handle hardware bundled with firmware, software and support.

Cost accounting at the SKU and BOM level is where credibility is earned. We work gross margin down to component cost, sequence capex against the tape-out and qualification roadmap, and lay out the working capital cycle from supplier deposits through inventory to customer collection. Design-win pipeline tracking sits alongside the financial model, not separate from it.

Flow provides financial modelling, FP&A and fractional CFO advisory to AI infrastructure and semiconductor companies across AI accelerators, networking silicon, edge inference hardware, fabless designers and GPU cloud providers.

KPIs to track for "AI infrastructure & semiconductors" startups

We're very 'KPI-driven' fractional CFOs, and we make sure to monitor the right metrics for your startup.

Design wins booked

Design-in to design-win rate

Revenue per design win

Gross margin by SKU

Wafer / die yield

Capex vs roadmap

R&D as % of revenue

Inventory turns

DSO / DPO cycle

Customer concentration

Foundry capacity committed

Bookings to billings ratio

Financial modelling for "AI infrastructure & semiconductors" startups

As fractional CFOs, we build KPI-driven financial models that are insightful and easy to maintain.

Financial modelling is both art and science - models must be robust, but also understandable, and useful for both internal planning and VC fundraising purposes. Hire a fractional CFO who knows how to handle both sides of the equation.

SKU-level BOM and gross margin

Gross margin built from die size, package, test cost and yield assumptions per SKU, with NRE recovery modelled across the programme volume. Shows whether the next node delivers the margin uplift the roadmap promises.

Tape-out and capex roadmap

Mask costs, qualification spend and capital equipment phased against the tape-out and product introduction schedule. Ties engineering milestones to the cash they actually consume rather than the calendar plan.

Design-win pipeline to revenue

Design-in, design-win and ramp probabilities translated into revenue by customer programme over the multi-year qualification cycle. Closes the gap between the sales pipeline and what gets booked years later.

Wafer commitment and inventory model

Foundry capacity commitments, wafer bank policy and finished-goods inventory mapped against the customer order book. Surfaces obsolescence risk before it becomes a write-down.

Hardware-plus-software revenue recognition

ASC 606 allocation across silicon, firmware, software stack and support entitlements for bundled deals. Stops accounting from distorting the gross margin signal investors and boards rely on.

Working capital cycle

Supplier deposits, foundry milestone payments, channel inventory and customer DSO laid out on a single cash conversion schedule. Tells the board how much working capital each incremental dollar of revenue actually consumes.
