We are Stax, a specialist deep tech headhunting firm. We have been retained by one of the fastest-growing AI companies in Europe to secure their foundational Chief Financial Officer (CFO).

Moving away from the fragile model of renting centralised cloud APIs, our client has engineered a breakthrough, first-principles AI infrastructure platform. Their technology allows global enterprises to deploy fully customisable, continuously learning models that remain entirely owned by the client.

Having shattered growth records by scaling from £1M ARR to £20M ARR in under three quarters, they are backed by elite strategic partners in institutional finance and are actively structuring a £50M+ Series A fundraise for this year. To support this explosive trajectory, they are executing an aggressive global roadmap with plans to expand operations into New York and Singapore within the next 12 months.

The Role

As CFO, you will act as the strategic co-pilot to the founders during a high-stakes corporate inflection point. You will instantly inherit a hyper-growth financial ecosystem, build an institutional-grade FP&A function from scratch, and architect the financial framework required to scale a multi-jurisdictional global footprint.

Key Responsibilities

  • Capital Strategy & Fundraising: Lead the upcoming £50m–£100m Series A roadshow, architect investor relations, and manage cap table mechanics for subsequent Series B/C horizons.
  • Global Expansion & Entity Setup: Establish the financial infrastructure, tax compliance, and legal entities required for rapid market entry into the US (New York) and APAC (Singapore) markets over the next 12 months.
  • Margin & Compute Architecture: Model and manage the unit economics unique to AI-native businesses, balancing heavy GPU/cloud infrastructure compute costs against high-velocity SaaS licensing software margins.
  • Enterprise Financial Operations: Oversee complex cross-border revenue recognition (IFRS 15 / ASC 606), corporate governance, and procurement cycles for blue-chip institutional finance and enterprise clients.
  • Team Scaling: Recruit, mentor, and scale a world-class, international finance and compliance team capable of supporting a multi-hundred-million-pound global valuation.

What We Are Looking For

  • AI-Native / DeepTech Pedigree: You have previously served as a CFO or VP of Finance inside an AI-native SaaS, developer infrastructure, or compute-heavy hardware/software platform. You understand gross margin pressures driven by raw infrastructure spend.
  • International Scaling Experience: Proven track record of managing multi-currency financial operations and driving corporate expansion across North America and APAC.
  • VC-Scale Track Record: Proven experience navigating a technology company through aggressive, multi-stage venture capital rounds (Series A through Series C+).
  • Hyper-Growth Velocity: You thrive in elite, high-velocity environments and have a proven history of scaling a technology business past the £50m+ ARR milestone.
