The house

Built for the owner who sells once.

Halstead was founded in London in 2004 by a merchant banker and a former head of M&A — on the belief that a private sale deserves the discretion of a merchant house and the rigour of a prospectus.

Reputations aren't announced. They're remembered.

Founding

Why we only ever sell.

An advisor who also works for acquirers keeps a second client in every negotiation. We removed the question: Halstead holds no buy-side retainers, protects no acquirer relationship, and accepts one mandate per partner at a time.

The discipline shapes everything else. Processes stay quiet — codenames from the first call, data rooms opened to principals only, guidance set once and held. When a sale closes, it is entered in the book and announced only when both parties want it read.

Principles

Three rules, no exceptions.

Discretion before marketing

No client list, no press without consent, no case studies with names. The work speaks in codenames.

One book, one partner

The partner you meet runs your process personally, from the first call to the entry in the book.

No buy-side retainers

We act for sellers. There is no acquirer relationship to protect and no conflict across the table.

Partners

The names on the door.

Every mandate is led personally by one of the partners below — no leverage pyramid, no hand-offs. We do not print their faces; discretion begins at home.

Marcus Halstead

Founding Partner · Sell-side

Former head of M&A at a London merchant bank. Twenty-two years of private sales; not one leaked.

Cecily Vane

Founding Partner · Capital

Built the capital and minority practice. Prices a business against the whole market, not the first bidder to call.

Oliver Rourke

Partner · Valuation & Opinions

Writes the opinions boards keep. Formerly of a Big Four valuation practice; tested in four jurisdictions.

Chronology

2004 → 2026.

Two names, one book

Founded in London to act for sellers only — one mandate per partner, recorded by hand.

First cross-border close

A family engineering group sold to a Nordic strategic — the first of many cross-border entries.

The opinions practice

Fairness opinions become a standalone practice after a decade of board work.

The capital desk

A dedicated desk for minority and growth-capital mandates opens alongside sell-side.

Forty-one entries

Forty-one closings in the book; the mandates behind them still private.

Sell once. Sell well.

A first conversation costs an hour and binds nothing. Everything after it is under NDA.
