Financial Controller

At fin-house, we are fuelling startups, scaleups and SMEs with awesome finance teams. The problem: The current go-to for start-ups and SMEs is outsourcing their finance function and team to accountancy firms who are very far removed from the business and often simply produce numbers without context. Our solution: At fin-house, we deliver 'in‑house'. This means our clients will have a team IN their business, providing proactive insight, advice and commercial support, enabling them to make the right decisions at the right time. We make sure our clients get the finance function they need, when they need it, seamlessly integrated into their business.

The key bits:

• Location: We are based in Waterloo (London) with a minimum of three days in the office a week.
• Salary: £70,000 to £80,000 depending on experience.

The role:

Our fin‑leads head up the finance function across their portfolio, leading teams and embedding finance at the heart of each organisation. They drive forecasting, planning and commercial insight, connecting day‑to‑day performance with long‑term strategy.
