About

I know what it feels like to be in your seat.

With 20+ years of experience in commercial finance, I've worked across corporate, startups and scaleups. I meet your business where it is now and get you ready for the next stage.

As an investor and CFO of ZuBlu, a VC-backed startup, I co-raised Pre-Series A funding, led due diligence, and presented to 700 investors at the Hong Kong Stock Exchange. We had fast growth, a multitude of different projects and little runway, I understand the challenges you're facing.

I'm here to support founders through exactly that process. Robust cash modelling, fundraising prep, investor relations. And building a finance function that's future proof for Series B and beyond.

Before that, a decade in large retail. Topshop, where I led the finance team through the Beyonce Ivy Park partnership. And most recently Trinny London, where I built the integrated financial models that supported fundraising and investor engagement. That contract started at 3 months, I was there almost two years across multiple fundraising projects.

I work remotely and take on a small number of clients at a time. From 2 days a month to 2 days a week depending on your business needs.

How I work

How I work with you

Engagements are always scoped to what you actually need, not a fixed package. We'll work it out on our first call.

Fractional CFO
Strategic finance leadership, without the full-time hire.

Your CFO without the full-time salary, the equity ask, or the six-month hiring process. I embed in your business, get to know your numbers, and give you the strategic finance layer that turns traction into a fundable, scalable company.

  • 2 days a month to 2 days a week, scoped to what you need
  • Integrated financial modelling (P&L, balance sheet, cashflow)
  • Fundraising preparation and investor materials
  • Cash flow and runway management
  • Board and investor reporting
  • Strategic planning and scenario analysis
  • Finance function build, ready for Series B and beyond

Day rates from £800. Monthly retainers scoped on engagement. Always transparent, always agreed upfront.

Who I work with

Built for founders at the messy middle.

Pre-Series A to Series A+. When you've got real traction but the finance function hasn't kept up.

01
You're doing the finances yourself

Or you have a bookkeeper and a prayer. You're spending time each week on something that needs a strategic layer above it and building for the next stage.

02
You're about to raise (or want to)

You need a model that holds up under scrutiny, materials that tell the right story, and someone who's actually been in that room. I've raised Pre-Series A. I know what investors push on.

03
You're in DTC, retail or consumer

I've spent 20 years in this world. I understand your seasonality, your unit economics, your margin pressures. I don't need a three-week onboarding to get up to speed.

04
You want a partner, not a report

You don't need someone to produce a deck once a month and disappear. You need someone who's actually in the business with you, asking hard questions, and telling you the truth.

Not quite right? I keep a network of trusted finance professionals across sectors and stages. If I'm not the right fit, I'll tell you and point you in the right direction.
