An international finance leader with 25+ years across SaaS, High Tech and telecoms, spanning VC, PE and publicly listed companies.

Hands-on and commercially minded, with a track record of scaling finance functions through hypergrowth, funding rounds and trade sales.

Career built across the US, Ireland, France, the Netherlands and the UK.

Scaling Finance for Hypergrowth — Building FP&A, revenue operations and financial planning processes to support 10x business growth, from Series E scale-ups to global public companies.

Fundraising & Investor Reporting — Navigating funding rounds and investor reporting requirements, with direct experience through a Series E raise and ARR scaling to €100M+.

Financial Control & Compliance — Implementing SOx-compliant controls, group treasury and multi-entity funding structures across 10+ legal entities.

M&A & Exit Readiness — Group financial controllership through a private equity MBO and trade sale, with hands-on refinancing and post-acquisition integration experience.

Senior finance leadership without the full-time overhead — a steady hand through funding rounds, scale-up growth and board governance.

Having led finance for Mambu and Salesforce, and scaled teams through 10x growth, I bring public-company discipline to high-growth, venture-backed environments.

I focus on operational efficiency and strong financial control, without slowing the business down.
