Head of Finance

The AI Operating System for Private Capital. Capsa AI Private capital funds have to find potential investments, research and analyse them thoroughly, monitor them over time, drive improvements, and decide when to buy and sell. Historically, these processes have run on people; we are building the AI Operating System that will run them in the future. We're focused, ambitious, and obsessed with building a category-defining company. In the last 12 months we've grown ARR 15x, achieved product–market fit with leading multi-billion-dollar PE firms, and expanded across the US, UK, and Europe. Now we're doubling down: we've raised a large Series A from top-tier VC investors to scale the team. We're hiring hyper-talented people who want to work at the forefront of AI and revolutionise an industry.

At a glance:

• Location: London, UK (Hybrid, in-person 4 days per week)
• Team: Finance & Operations
• Experience Required: 8+ years in finance including Head of Finance, FP&A or Controller leadership at a high-growth B2B SaaS or fintech startup. Qualified accountant (ACA, ACCA, CIMA, or US equivalent), with Big Four or top-startup grounding.
• Compensation: Top of market. Competitive base + OTE

The role:

• Build and run the finance function. Player‑coach today, full leader as the company and team grow under you.
• This is the senior‑most finance seat at the company. You own the model, the board pack, and the close yourself this year.
• Stand up FP&A, controls, and the financial readiness that takes us from Series A to Series B and beyond.
• You report to the CEO, work in lockstep with the founders, and partner on every commercial and capital decision the company makes.
• As you hire, develop a small finance team, and scale the function, the time you spend in the numbers shifts to time you spend building the function.
• CFO on the runway as we scale through Series B and beyond — the transition is driven by what you build.

The opportunity:

• The operating model. ARR, headcount, cost, cash, runway. The single source of truth the board and management run off, built and maintained by you.
• Board reporting and investor relations. Monthly board pack, quarterly investor updates, KPI dashboards.
• FP&A cadence. Monthly close, variance analysis, rolling forecast, scenario modelling.
• Series B readiness. Lead financial diligence prep, build the data room, support the CEO through the raise.
• Strategic and commercial partnership. Unit economics, pricing, deal structuring with PE customers.
• Controls and oversight. Manage the outsourced stack - accountancy, audit, tax, payroll, UK and US accounting.
• R&D tax credits and grants. UK and US claims captured year on year.
• Material cash. Cap table and equity administration.
• Treasury and cash management. Cash placement, GBP/USD FX, banking relationships, venture debt as Series B approaches.
• Team and systems. Hire and manage a small finance team (1–2 reports in 12 months).

Why Capsa:

• Exceptional traction. 15x ARR growth in 12 months, PMF with top PE funds managing over $1tn AUM.
• Define the function. First senior marketing hire at a category-defining AI company.
• Backed by the best. Top VCs and senior PE execs from Warburg Pincus, KKR, and Goldman Sachs.
• Major upside. Meaningful equity in a company growing 15x year on year.

Track record:

• 8+ years in Finance. Including Head of Finance, FP&A or Controller leadership at a high-growth B2B SaaS or fintech startup.
• Qualified accountant (ACA, ACCA, CIMA, or US equivalent), with Big Four or top-startup grounding.
• Operator, not just controller. You've owned the operating model and the board pack yourself.
• Series B+ raise experience. You've supported a CEO through a fundraise.
• Multi-entity, multi-currency. UK and US operations, GBP and USD reporting.
• Academic foundation. Bachelor's degree minimum 2:1 from a leading university.

How You Lead:

• Player‑coach by instinct. You're equally credible building the model on a Monday and presenting it to the board on a Tuesday.
• Strong point of view on commercial trade‑offs. You don't just report the number.
• Builder. You're choosing this role because the function isn't built yet, and that's the appeal.
• Direct communicator. You make calls, write them down clearly, and tell the team why.
• Genuinely curious about AI. Using it, breaking it, embedding it into how the finance function runs.

If this opportunity excites you, we'd like to meet you. Initial conversations are direct and substantive, going deep on the work, the team, and what you'd own in the first six months.
