Interim CFO London
When a London company needs a senior finance leader in the seat now — a departure, a turnaround, a fundraise, or cover before a permanent hire — an interim CFO fills the gap without a rushed full-time decision. Hayat Amin steps in at short notice with operator-side exit experience and dual UK/US investor fluency, stabilises the finance function, and hands over clean.
When founders bring in an interim CFO
- Sudden departure. The CFO or FD has left and the board pack is due.
- Live fundraise. A raise is in motion and the numbers need senior ownership through close.
- Turnaround or cash crunch. Runway is tight and decisions can't wait.
- Pre-hire bridge. Cover the seat while you run a proper search for the permanent CFO.
- Systems or audit event. A migration, first audit, or diligence sprint needs a steady hand.
What you get
Full-time or near-full-time presence for the length of the engagement: board and investor reporting under control inside the first weeks, a cash-flow model the team trusts, and a handover pack so the permanent hire inherits order, not chaos. On-site across Tech City, the West End, and the City as the situation needs.
Interim, fractional, or part-time?
Interim is full-time cover for a fixed window. Once the acute situation is handled, many London founders convert to an ongoing part-time CFO or fractional CFO retainer. Compare providers in the 2026 Best Fractional CFO London ranking.
