Altherum — CGPH ecosystem
Altherum is the private-market infrastructure of the CGPH ecosystem. It exists so that selected real and alternative assets can be verified, structured, held, subscribed and administered with the same discipline an institution would expect anywhere else. The technology layer records ownership and makes it traceable. It does not create quality, and it is never the reason an asset is worth holding.
Infrastructure material — intended for professional counterparties
Definition
Private-market infrastructure is easy to overstate. The clearest way to describe Altherum is to say plainly what falls inside its perimeter and what does not.
Blockchain is not the asset, but the infrastructure that allows trust, traceability and distribution to scale.
An asset earns its structure, and a structure earns its technology. The order is never reversed.
Operating model
The order of work is deliberate and never reversed: an asset earns its structure, and a structure earns its technology. Where the first step fails, the following ones are not attempted.
01
The asset is assessed on what it is: condition, nature, verification of provenance and the references available for its valuation. An asset that does not stand on its own is not improved by being represented digitally.
02
What an owner actually holds — title, encumbrances, enforceability, the jurisdiction whose law applies — is settled in documentation first. A record layer reflects rights; it does not create or enlarge them.
03
Assets are verified and held within institutional custody arrangements before any tokenized representation exists. Custody is part of the structure, not an accessory to it.
04
In alternative assets the constraint is rarely demand. It is access: high entry thresholds, fragmented pricing dynamics and limited visibility on exit. Altherum addresses that constraint structurally, through fractional ownership and standardized, traceable records.
05
Verified provenance, secure custody, structured onboarding and clear legal frameworks are treated as prerequisites rather than refinements. Fractionalization without them is not a model worth scaling.
06
Where the asset, the rights or the documentation do not support a structure, the answer is that nothing should proceed. That conclusion is part of the discipline, not a failure of it.
Technology does not replace asset quality, legal rights, valuation, due diligence, custody, eligibility, investor protection or the applicable documentation. Everything below sits on top of those, never instead of them.
Ownership
Three pathways were demonstrated in the Monte Carlo environment of June 2026. Each leads to the same outcome — ownership structured and administered through the same infrastructure — and each is available only where the specific structure, its documentation and the eligibility rules of the reader's jurisdiction allow it.
Single-buyer acquisition
A single buyer acquires the asset outright, through traditional auction or negotiated dynamics, with the ownership record and subsequent administration carried on the same infrastructure.
Availability of any specific asset, and the terms on which it could be acquired, exist only in that asset's documentation.
The pathways describe how ownership can be structured. They are not products on offer, and nothing on this page indicates that a subscription is currently open.
Perimeter
Two families of assets sit inside the perimeter. They describe the kind of asset the infrastructure is designed for — not a catalogue, and not a statement that any category is currently available.
Tangible assets whose value rests on condition, title and a realizable cash path, and whose ownership benefits from precise records and clear custody arrangements.
Curated alternative assets where provenance and verification are decisive and where traditional ownership models have limited access rather than demand.
Presence of a category above describes the design of the infrastructure. It does not imply that an asset of that category is available, offered or open for subscription.
Seven stages, in order. Most of the work happens before anything is represented digitally.
Lifecycle
Select a stage to see what actually happens there. The sequence can stop at any stage, and most of the work sits before anything is represented digitally.
Stage 01
An asset or a structure is examined on its own merits: what it is, who holds it, what the intended path to value is, and whether the file is coherent enough to continue.
No stage of this lifecycle creates a right, an entitlement or an expectation of liquidity. What a participant holds, and what they may do with it, is defined by the documentation of the specific structure and by applicable law.
Governance
Verified provenance, secure custody, structured onboarding and clear legal frameworks are the conditions under which the infrastructure is used at all. Where one of them is missing, the structure is not built.
Participation in any structure is restricted to eligible counterparties and remains subject to onboarding, KYC/AML procedures, conflict checks, internal approvals, jurisdictional restrictions and applicable law.
Information about an asset or a structure is shared on a controlled basis, with the parties concerned and through the agreed channel. Nothing on this page constitutes information about a specific structure.
Advisory work, infrastructure services and the role of any issuer or vehicle are distinct. A party acting in one of those roles does not thereby act in the others, and none of them is a substitute for a participant's own advisers.
Where anything in this material differs from the documentation of a specific structure, the documentation prevails. This page is a description of an operating model, not a term sheet.
Personal data collected during onboarding is processed under CGPH's privacy documentation and only for the purposes of eligibility assessment, administration and legal obligations.
Roles
Altherum sits inside the CGPH ecosystem, alongside businesses with different roles. Reading them as one service, or one legal person, would be a mistake — and a professional counterparty should be precise about which perimeter they are dealing with.
Based in Monaco, Altherum provides the private-market infrastructure described on this page for selected structures originated within the ecosystem. It is not an advisory business and it is not a discretionary manager.
The independent advisory business of the ecosystem, based in Paris La Défense. Where advisory work is provided, it is provided by that entity under its own engagement, and it is a different service from the infrastructure described here.
Any issuer, vehicle or structure through which participation is offered is a separate legal person with its own documentation, governance and obligations. Nothing here states that the advisory entity, Altherum and such a vehicle are the same legal service or the same entity.
The holding level of the ecosystem. Each business line is carried by its own legal entity, in its own jurisdiction, with its own obligations; an arrangement made with one does not bind another.
Which entity is your counterparty, and in what capacity, is established in the engagement or transaction documentation — never assumed from this page.
Collaboration
Holders of a real or curated alternative asset, or sponsors of a structure, who need ownership, subscription and administration handled properly rather than improvised.
Bring the asset, the title position and the documentation that exists today. The first question is whether the asset and the rights stand on their own.
Eligible professional counterparties assessing how participation in private assets would be recorded, administered and reported before considering any specific structure.
Start with the operating model, the onboarding requirements and the documentation standard. Nothing specific is discussed before eligibility is established.
Regulated advisors and distribution professionals whose own clients ask about private-market access and who need to understand exactly where this infrastructure begins and ends.
The starting point is the role boundary: what Altherum does, what it does not do, and what remains the responsibility of the advisor and their own regulator.
Custody, legal, valuation, verification and technology counterparts whose work is part of how a structure holds together.
A collaboration is assessed on capability and on compliance fit, and is documented before any joint work begins.
A conversation is exploratory and commits neither side. No acceptance, onboarding, participation or collaboration is promised by it, and each remains subject to review, compliance clearance and written documentation.
Demonstration
13 June 2026 — Monte Carlo, Monaco
On 13 June 2026, Altherum Tokenization was presented at a private event in Monte Carlo to investors, family offices and wealth-management professionals. The event was deliberately not structured as a product demonstration but as a live environment: a tokenized private auction for fractional ownership of curated assets, through which the three ownership pathways described above were shown end to end.
The point being made was a reframing rather than a launch of a technology product: tokenization treated as market infrastructure and as a distribution design, with the asset — not the representation of it — remaining the subject.
FAQ
Altherum is the private-market infrastructure of the CGPH ecosystem, based in Monaco. It supports selected real-world-asset structures, club deals and private placement notes originated within the ecosystem, providing an ownership and records layer together with subscription, administration and reporting workflows. It is not a discretionary asset manager and it is not an investment product.
Tokenization is the infrastructure, not the asset. Records on-chain make ownership traceable and transferable in accordance with the documentation; they do not create value, rights or quality. An asset that does not stand on its own is not improved by being represented digitally.
The asset is assessed on what it is, on the rights attaching to it and on the documentation supporting it. Provenance is verified and valuation references are gathered on their own basis before any structure or record is created. Where the asset or the rights do not support a structure, nothing proceeds.
Clear legal frameworks, secure custody, verified provenance and structured onboarding are prerequisites rather than refinements. Assets are verified and held within institutional custody arrangements before any tokenized representation exists, and participants are onboarded through eligibility, KYC/AML and jurisdictional checks before any subscription workflow is opened.
Nothing here states that a secondary market exists, that a transfer will be possible at a given time or price, or that any return will arise. Transfer and exit follow the terms of the specific structure and the constraints of the market for that asset. No performance, yield or return figure is stated on this page.
This page describes an operating model. It does not state that any asset, structure or subscription is currently open or available, and it is not an offer or a solicitation. Availability, if any, exists only in the documentation of a specific structure and only for eligible counterparties.
They are different perimeters. CGPH Banque d'Affaires is the independent advisory business of the ecosystem, based in Paris La Défense; Altherum, based in Monaco, provides infrastructure. Any issuer or vehicle through which participation is offered is a further, separate legal person. Advice, infrastructure and issuance are not the same service and not the same entity.
No. The infrastructure is applied selectively, to structures where it is genuinely the right answer, and only where the underlying asset and the rights already stand on their own.

This page describes the private-market infrastructure of Altherum within the CGPH ecosystem and is intended for professional counterparties, for preliminary discussion only. It is not an offer, a solicitation, an investment recommendation, a financing commitment, legal or tax advice, or a guarantee of any outcome, and it does not indicate that any asset, structure or subscription is currently available. Technology does not replace asset quality, legal rights, valuation, due diligence, custody, eligibility, investor protection or the applicable documentation. Participation in any structure is restricted to eligible counterparties and remains subject to onboarding, KYC/AML procedures, jurisdictional restrictions, final documentation and applicable law. The entities referred to are separate legal persons in their own jurisdictions, with distinct roles; nothing here states that advisory services, infrastructure services and any issuer or vehicle are the same legal service or the same entity.
