ESTABLISHED 1998 · MADRID · LONDON · MARBELLASTRATOS
A private advisory partnership

Strategic counsel for owners with too much to lose.

We work, very quietly, with founders, families, and closely-held boards on the handful of decisions that compound over a lifetime: succession, capital allocation, cross-border structure, and the rules that hold a family together after the founder is gone.

PP. 002 — 005A letter from the partnership

On what we do, and why it does not look like consulting.

We are a small partnership. There are three of us, three associates, and twelve clients at any given time. We do not take a mandate we cannot finish ourselves, and we do not sub-contract to a network.

Our work is the work nobody else wants to do quickly: the succession plan that takes six years, the family constitution that takes three drafts, the cross-border restructure that touches four jurisdictions and outlives two governments.

We do not sell products. We do not earn commission. We are paid by the hour and by the year, on fixed retainers, with no contingent fees of any kind. Our partners are the third generation of an industrial family, a tax barrister in private practice, and a former family-office CIO.

Most of our clients arrive on referral, on a recommendation from a private banker, a notary, or another client. We have never advertised.

If you have arrived here intentionally — please write. We will read it the same week.
