Where CFO Excellence creates value

The right CFO setup depends on the situation. Some businesses need full ownership. Others need targeted intervention to unlock performance, improve control or accelerate transformation. Use this guide to choose the right model.

Who CFO Excellence works with

The work is built for leaders who need finance to move performance, strengthen control and improve decision quality.

PE Firms & Operating Partners

Translate the investment thesis into sharper KPIs, disciplined reporting, stronger cash control and an execution rhythm the portfolio team can actually run.

CEOs & Founders

Build visibility, control and decision quality as complexity increases, especially when growth, ownership change or underperformance expose finance gaps.

Portfolio CFOs & Leadership Teams

Add extra senior capacity for transformation, FP&A, business control, ERP/EPM, shared services, integration or performance acceleration.

Boards, Lenders & Investors

Improve the quality of the discussion around EBITDA, cash, leverage and execution readiness with a more credible single version of the truth.

Built for businesses where finance has to change outcomes.

CFO Excellence typically supports businesses between €50m and €1bn+ revenue where performance, control or complexity require a step change. The focus is simple: improve EBITDA, strengthen cash and build a finance function that drives decisions, not just reports them.

This means sharper forecasting, stronger liquidity control, clearer value drivers and a finance organisation that can support growth, integration or exit — with credibility towards boards, lenders and investors.

Core value-creation themes

  • EBITDA & Cash Performance
    Improve visibility, challenge assumptions and create an operating rhythm that drives action.
  • Finance Transformation
    Upgrade structure, planning, controls, systems and team capability as the business scales.
  • Integration & Change
    Support post-merger integration, redesign and complex transition with financial discipline.
  • Investor-Grade Execution
    Align management, board and investor expectations with sharper metrics and clearer accountability.
