Fractional CFO

I help founders and executives focus on growth by building robust and scalable financial strategies. My approach is structured, tech-enabled and candid - offering clarity, not complexity.

With 20+ years of experience spanning Shell's global trading and corporate finance organisation along with advisory and board roles with startups, I bring together deep finance knowledge and a passion for automation.

I've supported multi-billion-dollar P&Ls, structured M&A transactions and built investor-ready financials for companies raising seed to Series A rounds. Now I work with growth-stage EnergyTech and FinTech companies as a fractional CFO - bringing the rigour of large-cap finance to businesses that need strategic firepower without the overhead.

Frequently Asked Questions

Answers to common questions about working together.

A fractional CFO is an experienced finance leader who works with your company part-time - typically 1-2 days per week or on specific projects. You get strategic CFO-level support without the cost and commitment of a full-time hire.

Bookkeepers and accountants focus on historical record-keeping and compliance. A fractional CFO focuses on forward-looking strategy: fundraising, financial planning, cash management, and helping you make better business decisions.

I work with companies from seed through Series B - typically those with some revenue traction who are preparing for institutional funding, need to professionalise their finance function or are navigating a complex financial situation.

My focus is on EnergyTech and FinTech. My 20+ years at Shell in trading and energy, combined with startup advisory work, gives me deep domain expertise in these sectors.

Most clients start with a discovery call. From there, we agree on either a monthly retainer or a scoped project. I work remotely and integrate with your existing team and tools.

Typically within 1-2 weeks. For urgent situations like fundraising timelines or cash crises, I can often accommodate faster.
