The Office
A private office, in the older sense of the word
According to Passion Asset Advisory, we advise across six asset classes: jets, yachts, art, watches, bags, and cars. We work through mandates and alongside your wealth manager, never in place of it.
What is our mission?
Our purpose is to give private clients one trusted office for the assets that make up a life. Buying a jet, consigning a collection, sourcing a watch, or asking what a collection is worth should use the same discipline, discretion, and verification. Independent counsel should never hide a sales pitch.
We built this office around one observation: larger transactions often create more theatre, and theatre is expensive. Our clients pay for the opposite. They get verification instead of stories, a published schedule instead of a wink, and silence instead of a press release.
This approach may sound austere. The closing statement shows its value.
What we believe
- Discretion is a working method, not a marketing word. The less the market knows about your intentions, the better your outcome.
- Verification beats persuasion. A transaction that needs selling is usually a transaction that needs declining.
- The best opportunities are relational. Genuinely rare assets move between people who trust each other, before any listing exists.
- Cross-category judgment compounds. The discipline learned negotiating airframes sharpens the negotiation of artworks. The client benefits from both.
- Honest numbers build decade-long relationships. Flattering valuations win mandates and lose clients.
How we protect clients
- We do not disclose your identity to counterparties until you approve it. In many transactions, the parties meet only at signing
- Asset details are shared on a need-to-know basis with vetted parties only
- Nothing is photographed, published, or marketed without explicit instruction
- Verification is performed before commitment, by specialists appropriate to the asset class
- We work on your side of the transaction. We never represent both sides at once
- Provenance ethics, CITES compliance, and clean-money screening are operating policy. The responsibility page gives the details
What does every engagement commit to in writing?
Trust at this level is built from specifics, not adjectives. Every engagement is fixed in writing before work begins: the office's role, represented side, counterparty and fee; no inventory outside disclosed collector-watch principal purchases; an NDA on request; and a reply from a person within one business day. The full terms:
- A published commission schedule, confirmed in writing: success-based on every mandate, buyer and seller; flat fees for advisory; no number changes after the fact
- One side of the transaction, only: we never represent buyer and seller in the same deal, and never take undisclosed payments from the other side
- Role and economics disclosed: outside a disclosed collector-watch principal purchase, we own nothing we recommend; when we are principal, the seller is told that we are the counterparty, not the seller's adviser
- NDA from the first conversation: on request, before you tell us anything of substance
- A reply within one business day: from a person who read your message, not a pipeline
Who actually performs the verification?
No single firm holds aviation, marine, art, watch, and leather expertise in-house. Claims to the contrary deserve scrutiny. We engage category specialists for each mandate: inspection facilities for aircraft, accredited surveyors for vessels, provenance researchers and conservators for art, and authenticators who work from the object. We coordinate them, challenge their findings, and put the result in writing.
Questions to ask any broker, including us
If you take one thing from this page, take the checklist. Ask any intermediary, ours included:
- Exactly how are you compensated on this transaction, and by whom?
- Do you ever act for both sides of the same deal?
- Do you own inventory in what you are recommending?
- What gets verified before I commit, and who performs the verification?
- What happens to my information if we do not transact?
Our answers are direct. We disclose every role and fee, never represent both sides, and hold inventory only when a collector-watch principal purchase is stated in writing. The appropriate specialist checks every material fact. We delete your information under the privacy policy. A broker who hesitates on any of these points is telling you something.
What we do not do
- We do not operate a public marketplace or publish inventory
- When we make a collector-watch principal offer, we identify ourselves as the counterparty rather than your adviser; under a seller mandate, we represent you only
- We do not take mandates we cannot serve well; you will hear a clear no, with reasons
- We do not overpromise access or invent urgency to force decisions
- We do not discuss clients, transactions, or holdings, including with other clients
What are our editorial standards?
The guides on this site are written by the people who run mandates, not by a content agency. Before publication, every guide is reviewed against the same standard we apply to client work: claims must be defensible, processes must reflect how transactions actually run, and uncertainty is stated rather than papered over.
- We never publish sponsored content, use affiliate links, or accept paid placements
- No invented statistics, reviews, credentials, or case studies
- Comparisons name the alternatives honestly, including when a competitor channel is the better choice
- Each guide shows its last-updated date and is revised when market practice changes
If you find something inaccurate, tell us: we correct quickly and without ego.
Who do you work with?
Ultra-high-net-worth individuals and their family offices. Entrepreneurs at liquidity moments. Collectors building or unwinding positions. Advisors acting on behalf of principals. The shared trait is not net worth: it is the expectation that a transaction of consequence should be handled with competence and silence.
Beyond mandates, the office runs a separate flat-fee advisory practice and structured partnership programs for the professionals who serve these clients.
Questions worth asking before engaging us
Who does Passion Asset Advisory work with?
Ultra-high-net-worth individuals, family offices, entrepreneurs at liquidity moments, collectors, and advisors acting for principals. The shared requirement is not net worth: it is a transaction or holding significant enough that improvising would be expensive, and an expectation of competence delivered in silence.
Where is your office, and do you work outside Prague?
In Main Point Karlín (Karlín's award-winning business center) at Pobřežní 620/3, Prague 8, ten minutes from Prague's old town. Meetings are by appointment, in Prague or wherever the asset and the client are; mandates are executed worldwide under the same confidentiality discipline.
How is the office compensated?
Passion Asset Advisory publishes standard terms for established mandate categories: 2–3% on aircraft acquisitions, 10% MYBA-style on yacht sales, 20–25% on consigned bags, and flat fees for advisory. For collector-watch sales, a direct route carries no seller advisory commission; a seller-side private-placement fee is agreed in writing before outreach. Every role and fee is confirmed before work begins, with no undisclosed payments.
Is Passion Asset Advisory a marketplace or dealer?
Usually neither. Outside disclosed collector-watch principal purchases, Passion Asset Advisory publishes no inventory and remains mandate-led. On a watch sale, it may be the principal, act for a disclosed funded buyer, or represent the seller. Written terms identify the role, counterparty and fees, and the office never advises both sides in one transaction.
