Foster Swiss · Geneva, Switzerland
When your wealth
no longer needs you
to explain itself,
we have done our job.
International documentary wealth architecture for structures above €1M. We coordinate the documentation, the banking legibility and the continuity so that your wealth survives any review — and any generation.
The questions that determine whether your structure is ready
Most legally sound structures are not documented in a way that lets anyone else activate them. The Global Asset Map™ solves exactly that — in a document any person can follow without needing a lawyer.
Source of Wealth is no longer assumed. Swiss private banks require historical traceability of wealth. FS Banking Readiness™ prepares that file before the bank asks for it.
The new FINMA regulation, the Swiss AMLA and the VSB 20 standards have changed significantly since 2020. What was sufficient then may not be enough in a current KYC review.
Legacy Protocol™ ensures the structure can be activated within the first 30 days, with an access map, a letter of instructions and a family protocol that does not depend on the founder's memory.

Why we exist
Foster Swiss does not manage your investments.
It does not sell funds. It is not a bank.
It takes commissions from no one.
It builds the architecture that allows your wealth to
be understood, defended and transmitted
without depending on you.
Most international wealth structures are well built from a tax and legal standpoint. The problem is not the structure. The problem is that only the founder understands it. And when the founder is not there, the wealth is not lost — it is frozen.
Four services.
One single purpose.
We take no commissions from banks or financial products. The only incentive is that the work be excellent. Fees set by scope, not as a percentage of wealth.

Why Foster Swiss
and not another firm
The business owner who comes to Foster Swiss has already spoken to their lawyer, their banker and probably some adviser. The question is always the same: what makes this firm different?
Documented, proprietary methodology
The TENTÁCULOS® method, Global Asset Map™, FS Banking Readiness™, Legacy Protocol™, FS Continuity Score™. These are not generic names — they are methodologies developed over more than 15 years with Latin American structures.
A Swiss private banking perspective, from Geneva
Foster Swiss works where the banks that review the structures are. Not from Madrid, Mexico City or Miami. From Geneva. To the standard applied by tier-1 Swiss private banking.
Four experts with distinct territories
Not a generic team. Four specialists with their own editorial territories: wealth architecture, banking compliance, documentary KYC and international structures.
Complete independence
Foster Swiss does not manage assets, does not sell funds and takes no commission from any bank or financial product. Fees are fixed by scope. The only incentive is that the work be excellent.
The sector's only editorial system in Spanish
No Spanish-speaking boutique private wealth firm has four active editorial series across YouTube, Substack and Spotify. Clients arrive knowing the methodology before the first meeting.
Absolute confidentiality to Swiss standards
NDA signed before any work begins. Information protocol to Swiss private banking standards. No data about the client's structure is shared with third parties under any circumstances.
"The Foster Swiss client is not looking for one more firm. They are looking for someone who already understands the problem before they have finished explaining it."
What you need to know about your wealth in 2026
Six concepts that determine whether an international wealth structure can remain in European private banking. Regulation has changed more in the last three years than in the previous two decades.
Source of Wealth
Documentation of the historical origin of the wealth. Swiss private banks require proof of how the total wealth was accumulated — not only current income. Sale contracts, historical tax returns, professional valuations. Without this documentation, onboarding at a tier-1 bank is not possible in 2026.
UBO — Ultimate Beneficial Owner
The real natural person who owns or controls a structure, identified by name, surname, date of birth and identity document. Switzerland's new 2026 law requires the UBO to be registered. Structures with generic beneficiaries are no longer compatible with European private banking.
KYC — Banking Due Diligence
The continuous review process applied by any private bank. In 2026, KYC is no longer a one-off — it is continuous and periodic. FINMA and VSB 20 set minimum standards that have changed significantly since 2020.
CRS — Automatic Exchange
The Common Reporting Standard connects more than 120 jurisdictions. What a bank in Switzerland reports and what a client declares in Mexico or Colombia is compared automatically. Inconsistencies trigger bank reviews without prior notice.
Economic Substance
Swiss banks require companies to have real activity: offices, local employees, decisions taken in the jurisdiction. Since 2023, structures without substance are automatically rejected in onboarding processes.
Documentary Continuity
The ability of a structure to be activated by people other than the founder. The Global Asset Map™ is the instrument that guarantees that continuity: for every asset, who can activate it and with exactly what documentation.
The team · Geneva
Four experts.
Four territories.
One single purpose.
Foster Swiss works from Geneva with a Swiss private banking perspective: documentation, traceability, Source of Wealth and a coherent banking narrative. We do not manage assets. We build the architecture that allows those assets to withstand any review process by an international financial institution.

SubscribeFrequently asked questions
What we are asked before the first meeting
These are the real questions. Not the ones a firm usually publishes — the ones that determine whether Foster Swiss is the right answer for your situation.
A wealth manager administers and grows your assets. Foster Swiss does not touch your assets — it builds the documentary architecture that allows those assets to be understood, defended and transmitted without depending on you. We work with the map, not the territory. We do not manage investments, we do not sell funds, we take no commission on financial products.
The 2023-2024 revision of the Swiss AMLA and the new FINMA standards require banks to carry out continuous, not one-off, KYC. A long-standing banking relationship does not exempt you from demonstrating Source of Wealth with up-to-date documentation. FS Banking Readiness™ prepares that file before the bank requests it — or on an urgent basis if a deadline is already running.
It is a 20-35 page document that, for every asset, company, account or vehicle in your structure, answers: what it is, where it is, who can activate it and with exactly what documentation, and what happens if the holder is not there. It also identifies the critical documentary gaps and delivers a prioritised action plan. It is delivered in a secure digital format and as a bound printed version. Its distribution is exclusive and confidential to the recipient.
Fees depend on the complexity of the structure: the number of jurisdictions, the type of assets and the state of the existing documentation. We work with fixed fees by scope, never with percentages of wealth or financial product commissions. The amount is set out in a personalised proposal after the assessment conversation, which carries no cost and no obligation. Write to us describing your situation and we will confirm the scope you need and the corresponding fees.
Switzerland has passed legislation requiring companies to register their real beneficial owner with the authorities. The register is not public but it is accessible to financial institutions and regulators. Structures that relied on Swiss anonymity — nominees, multi-layer arrangements without a documented UBO — are no longer compatible with current European private banking. FS Banking Readiness™ includes a compatibility review against this new regulation.
Since January 2024, the Corporate Transparency Act has required every LLC in the United States to declare its real beneficial owner to FinCEN. Existing LLCs had until January 2025. If you did not declare the beneficial owner, your Swiss bank may detect it during the next periodic KYC process. FS Banking Readiness™ includes a review of structures with a US nexus.
Write us MAPA, GLASS or CÓDIGO by direct message on LinkedIn, or complete the form on this page. We will reply within 24 hours to arrange a 30-minute conversation in which we assess whether your situation and the Foster Swiss methodology are the right fit. No obligation. No pressure. Just clarity.
Confidential review
The first conversation is an assessment, not a sale.
If your wealth exceeds one million euros and you hold assets in more than one jurisdiction, we can assess in 30 minutes whether your structure is ready for what is coming.
This request is entirely confidential. We reply within 24 business hours from Geneva.
