Chiltern Advisory · Fractional Finance & Operations

A Fractional CFO for the decisions that move the value of your business.

A senior CFO partner to the CEO and Board — shaping capital strategy, value creation and the path to the next round or exit. The forecasting, cash discipline and Board reporting that make the strategy credible run underneath, with COO depth included where the numbers need an operator behind them.

Why Chiltern

CFO leadership shaped by real-world scale — not just the theory of it.

  • Operator, not accountant

    Multi-$Billion P&L ownership inside AWS and Amazon — not a career spent observing growth from the audit side.

  • CFO + COO on one engagement

    Operational depth included on the same mandate, not billed as an extra or handed to a separate consultant.

  • One operator end-to-end

    No bench, no handovers, no junior delivery team. The person you meet is the person doing the work.

What we do

A Fractional CFO — with an operator's instinct.

Chiltern leads with strategic CFO work — capital strategy, value creation, M&A and Board partnership — and brings the forecasting, reporting and operational discipline underneath it. Where finance and operations meet, a former COO leans in on the same engagement.

Fractional CFO — core offer

Forecasting, cash, board reporting, FP&A, fundraising and exit readiness, led by a senior finance operator.

CFO+ with embedded COO

When finance issues are operational at root — pricing, productivity, cost-to-serve — COO depth is included, not bolted on.

Diagnostic sprints

Two-to-six-week CFO-led reviews that surface where margin, cash and growth are leaking.

Value-creation programmes

18–24 month CFO engagements for PE-backed value plans and founder-to-CEO transitions.
