The diagnosis
For most of the last century, hospitality has been written about as an industry. As floors and inventory. As RevPAR and occupancy. As a labor-intensive service vertical that, more recently, is being told to automate or be commoditised.
This is the language of accountants and the language of the people who will eventually replace the work entirely with software. It is correct, as far as it goes. It is also incomplete.
I have spent over thirty years in the tourism, travel and hotel industry. Senior leadership at Hilton, Marriott, Radisson and Titanic, built on early years at Swissôtel and Hyatt. Four continents. Cornell General Managers Program. Past President of Skål International Baku Club. A Carlson Rezidor award — The Best Hotel 2014, Deliver Results — with the operational receipts to defend it.
Today I run Greenmountains · Executive Consultancy — the practice through which I advise owners and operators across the service industry — hotels, restaurants, catering and events, spas, clubs and the groups that own them — on commercial and operational performance, pre-opening readiness and transition mandates. The operating truth I carry into those rooms is the same truth the next layer of hospitality — increasingly run by software — will need designed in from the start.
That arc — across four continents, from Hilton and Marriott to Radisson and Titanic, and now into the AI layer being built on top of them — taught me one thing the conference circuit cannot: hospitality has never been an industry. It has always been a craft. The industry was the scaffolding around the craft, and the craft was the reason any of it earned the right to exist.
The Turkish word for it
The Turkish language has a word — haysiyet — that English translates poorly. It is rendered, depending on the translator, as honor, dignity, integrity, or self-respect. None of these is wrong. None is sufficient. Haysiyet is the thing that is owed to a person because they are a person, and that a host either upholds or violates, every time.
A hospitality system that upholds haysiyet — for the guest, for the colleague, for the worker on the night shift — is a craft of human dignity. A hospitality system that hollows it out in the name of efficiency, optimisation, or shareholder return is a transaction at scale.
I have spent my career inside both kinds. I know the difference.
Why AI changes the cause, not the question
For the next thirty years, hospitality will be run by AI systems. That sentence is not a forecast. It is, increasingly, the operational reality from the front desk to the revenue model. The question is not whether to automate. The question is who designs the automation.
If the next generation of hospitality AI is designed by people who have never run a property — never stood in a lobby at 2:00 a.m. when a key system fails, never coached a frontline employee through a complaint that began as a misunderstanding and ended as a moment of grace — then it will optimise the metrics it can see and break the things it cannot.
The only way to keep haysiyet inside the system is to put the operational truth of over thirty years in the tourism, travel and hotel industry inside the room where the system is being built.
That is why this work exists. And that is why I take it on as an executive advisor inside the boardrooms where these decisions are made — through Greenmountains, on the owner's side of the table — not as a commentator on the outside.
What this commits to
Everything on this site is a facet of one cause. None of it is a service in isolation.
- Greenmountains · Executive Consultancy — the practice. Methodology drawn from the Cornell General Managers Program and over thirty years in the tourism, travel and hotel industry, delivered to owners and operators across the service industry — hotels, restaurants, catering and events, spas, clubs and the groups that own them — and to the technology companies shaping hospitality's next layer.
- Orophile Journeys — the independent travel advisory practice I founded, where the same craft serves the traveller instead of the operator. Its home is orophilejourneys.com, not this site.
- Orophile Edit — its editorial companion (orophileedit.com), where the craft is documented, not just practised.
- Build Life Puzzle — the coaching and mentoring practice built on the Missing Pieces of Life Puzzle book series (buildlifepuzzle.com). It is where individuals at midcareer apprentice into the cause, one missing piece at a time.
- Missing Pieces of Life Puzzle — the books themselves. Philosophical scaffolding. Books are how a cause survives longer than a career.
- Speaking and education — Cornell, Skål, Lambton, Fanshawe, Vatel, Boğaziçi — apprenticing the next generation institutionally. A cause requires apprentices, not customers.
The invitation
If you operate inside hospitality and you recognise the diagnosis above, the work is open to you. Hospitality groups — hotels, restaurants, catering and events, spas and clubs — can request a strategic audit through Greenmountains. Boards can schedule a governance conversation. Operators evaluating AI systems can request the Operator's AI Lens framework. Travellers who want to experience hospitality as a craft of human dignity can read about Orophile Journeys. Individuals at midcareer working on their own missing pieces can find the coaching practice at Build Life Puzzle. The next cohort of the Curator's Fellowship will be announced here.
The cause is too big for any one career. That is the point. It outlasts mine and yours both. It is enough to do honest work inside it.
