The Office
A private office, in the older sense of the word
What is our mission?
To give private clients one trusted office for the assets that make up a life — so that buying a jet, consigning a collection, sourcing a watch, or simply asking what it is all worth carries the same discipline, the same discretion, and the same standard of verification. And so that counsel, when counsel is all you need, is never quietly a sales pitch.
We built this office around one observation: the more money a transaction involves, the more theatre tends to surround it — and theatre is expensive. Our clients pay for the opposite. Verification instead of stories. A published schedule instead of a wink. Silence instead of a press release.
If that sounds austere, it is — right up until you read the closing statement.
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 — and the client benefits from both.
- Honest numbers build decade-long relationships. Flattering valuations win mandates and lose clients.
How we protect clients
- Your identity is not disclosed to counterparties until you approve it — many transactions complete with the parties meeting 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 — never both sides at once
- Provenance ethics, CITES compliance, and clean-money screening are operating policy — detailed on the responsibility page
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: a published commission, representation of one side of the deal only, no inventory and no spreads, 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
- No inventory, no spreads — we own nothing we recommend, so the advice has no warehouse to empty
- 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 — anyone claiming otherwise is selling. Verification is performed by category specialists engaged per 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: disclosed fee from your side only; never; no; everything material, by named specialists; it is deleted — see the privacy policy. A broker who hesitates on any of the five is telling you something.
What we do not do
- We do not operate a public marketplace or publish inventory
- We do not buy your asset cheap to flip it — we represent you, not a trading book
- 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.
- No sponsored content, no affiliate links, no paid placements — ever
- 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?
Deal-based commission, published openly: buyers pay a success commission on acquisition mandates (2–3% on jets, 10–15% on watches and bags) and sellers on sales and consignments (4–5% on jets, 10% MYBA-style on yachts, up to 25% on consigned bags) — the full schedule is on the How It Works page. Advisory is flat-fee. We hold no inventory, take no spreads, and accept no undisclosed payments.
Is Passion Asset Advisory a marketplace or dealer?
Neither. We publish no inventory, own nothing we recommend, and represent one side of each transaction under a confidential mandate. Marketplaces show what sellers choose to list; dealers sell what they own. A mandate-led office works the whole market — visible and off-market — for you alone.
