We take ownership of what falls between your providers.

Independent finance, tax and compliance for the UK and Irish entities of international groups, and for funds. We work alongside the accountant, auditor and CFO you already have, run the recurring work where you need us to, and stay on each issue until it is resolved.

Senior enough to challenge. Practical enough to execute.

Where problems start

The individual parts of a finance operation often work. The problems start between them.

Two practices

International groups

For Group CFOs, Finance Directors, Group Controllers and international finance teams responsible for UK and Irish entities.

For head office: a clearer, more reliable view of what is happening locally, from someone who stays involved until it is fixed.

When groups call us. A difficult audit, a missed group deadline, a UK acquisition, a new Group CFO, or directors at head office still to verify with Companies House.

Group practice and fees

Funds & financial services

For fund founders, CFOs, COOs, boards and management teams of funds, asset managers and investment businesses.

For the board and investors: institutional finance discipline, ready for due diligence, without a full-time senior hire.

When managers call us. A first close, an investor's operational due diligence, FCA authorisation, a change of administrator, or an audit finding.

Fund practice and fees
Why clients add THOTH

Senior judgement at boutique fees, from someone who has sat on every side of the table.

The principal does the work

Big Four-trained judgement without Big Four layers. Your first conversation, and every review, is with the person accountable for the result.

No migration

We work with your existing providers and systems. Nothing to unwind, no handover risk, no switching cost.

Independent

We are neither your auditor nor your bookkeeper. Head office gets an accurate view, and the local entity is judged on facts rather than interpretation.

Every side of the table

Component auditor for subsidiaries of German and French groups, group reporting for Deutsche Börse entities, group control and executive committee at Amundi. We know what each party needs to see.

Selected experience

The situations clients bring, already handled by the principal before THOTH.
