When your situation is too complex, too personal, or simply too important to hand to a conventional advisor — you need someone who genuinely understands your world.
Someone who has operated at the same level, who understands the pressures that come with success, and who can engage with the full picture — business, family, and everything in between — without judgement and without ever leaving the room.
My clients don't fit into boxes. Neither does the way I work. I bring 30 years of real-world experience to whatever you're facing — and I stay with it until it's resolved.
For high-achieving individuals who need a trusted thought partner — someone who can hold the full context of your business life, challenge your thinking privately, and help you make decisions with confidence. Not a coach. Not a consultant. Something more personal than either.
Some situations are too sensitive, too urgent, or too complex for your usual advisors. A dispute that crosses personal and professional lines. A relationship that needs careful navigation. A deal that needs someone to walk into the room. I handle it — discreetly, decisively, and completely.
Three decades at the intersection of hospitality, property, private equity and leisure means I know the right people in the right rooms. Whether you're evaluating an investment, entering a new sector, or simply need someone to open the right door — I'm that connection.
For those who value their time above everything. Whether it's finding the right restaurant for an important dinner, arranging something genuinely memorable, or navigating a situation that requires someone with taste and discretion — I take care of it.
"He worked closely with me to find a solution I would never have reached on my own. Completely discreet. Completely trustworthy."Private client — London
Jon Yantin is not a theorist. Over three decades he has operated at the very highest levels of hospitality, leisure, property and private business — building companies, navigating complexity, and sitting across the table from some of the most demanding clients and operators in the world.
As a founding partner of The ONE Group Europe, he led the F&B operations at ME Hotel London, Milan, and The Hippodrome Casino London — generating £30 million in combined annual revenues. He has advised NASDAQ-listed businesses, private equity firms, hedge funds, and family offices. Most recently, he oversaw the repositioning of The Royal Bell, a members club in Bromley.
What sets Jon apart isn't the CV — it's the instinct. The ability to read a room, hold complexity without losing the thread, and give you the honest answer even when it's uncomfortable. His clients value him not just for what he knows, but for who he is.
Your solicitor, your accountant, your financial advisor — they're all excellent at what they do. But they operate in lanes. Jon works in the space between them: where business crosses into family, where urgency demands judgement not process, where you need someone who has genuinely been there.
Not hired to tell you what you want to hear. Engaged because you want someone who will tell you the truth — who understands the weight of your decisions and the value of getting them right.
Everything discussed stays between us — always. Jon works with individuals for whom discretion is not optional. There are no assistants, no files shared, no follow-up marketing. Just one private relationship.
The situations that matter most rarely fit a brief. Jon is equally at home navigating a complex commercial negotiation, a sensitive family matter, or a decision that keeps you awake at three in the morning.
Every engagement begins the same way — with a conversation. No forms, no questionnaires, no obligation. Just an honest discussion about whether and how Jon can help.
Reach out through the form below, or call directly. Tell Jon as much or as little as you're comfortable with. All enquiries are handled personally and in complete confidence.
A 30-minute call, at no charge, to properly understand your situation. Jon will give you a candid view of how he can help — or be equally candid if he believes someone else is better placed.
Every engagement is different. Some clients need a single focused session. Others want ongoing, retained access. Fees and scope are agreed clearly upfront — nothing hidden, nothing open-ended.
From the moment you engage, Jon's full focus is on your situation. You'll have direct access — not an assistant, not a team — and he stays with it until you have what you need.
"He both solved the issue and saved me money well over and above his fee. He's like an all-in-one A-team — but it feels like talking to a friend."Business client — Commercial matter
JY helped me with a business issue I was struggling to resolve due to a personal connection. He both solved the issue quickly and efficiently and saved me money well over and above the fee we agreed. He's like an all-in-one A-team.
When I was looking for a new perspective on a tricky family issue I reached out to JY. He was extremely sympathetic to my predicament and worked closely with me to find a solution I would never have reached on my own.
Jon's ability to cut through complexity is remarkable. He brought board-level thinking to our situation but never once made us feel like a transaction. He genuinely cared about the outcome. The result exceeded everything we hoped for.
Clients & organisations Jon has worked with
Every engagement is agreed upfront. Jon works across short, focused sessions and longer retained relationships — the right structure depends on what you need. Start with a conversation.
You don't need to have it all worked out before we speak. Tell Jon what's going on — in your own words — and he'll give you an honest view of how he can help. There is no obligation, no pitch, and no one else in the room.
Jon will respond to you personally, usually within 24 hours.
The most valuable 30 minutes you'll invest this year might simply be an honest conversation. It's free, it's private, and you'll leave with more clarity than you arrived with.
