From 2001 to 2014 I ran a longevity clinic inside the Four Seasons in Miami. It saw more than 35,000 patients and at its peak earned about $24 million a year. People assume the hotel guests paid for it. They didn’t. Guests were a small share of revenue. The clinic was carried by local members on annual programs, people who lived twenty minutes away and came back every few weeks.
That lesson took me years to see clearly, and it is the reason I think the longevity clinic, as a stand-alone business, is the wrong container for most of what this industry wants to sell.
What a stand-alone clinic really earns
A longevity clinic carries the cost base of a medical practice: physicians, nurses, a lab relationship, insurance, a lease on good space in an expensive neighborhood. It has to fill that capacity every day. Most clinics I have seen since do not struggle because the medicine is wrong. They struggle because the chair is empty.
Filling the chair is expensive. A clinic has to find a customer, convince them to pay cash for something their doctor does not offer, and then persuade them to come back. Every one of those steps costs marketing money, and the clinic pays it again for every new patient. The ones that survive, as ours did, are the ones that stop selling visits and start selling a relationship: an annual program, a fixed fee, a reason to return.
Once you see that the relationship is the product, the obvious question is who already has one.
The members are already somewhere else
A hotel knows its guests. A gym sees its members two or three times a week. A residential community has its residents every day of the year. A clinic, if it is lucky, sees its patients twice a year.
The operator who already owns that relationship owns the cheapest route to a longevity customer. They don’t have to find the person. They don’t have to earn the trust from nothing. They already have the address, the habits and the frequency, which is exactly what a longevity program needs to work, because almost everything that extends healthy life happens between appointments: sleep, food, movement, stress, other people.
This is why I now spend my time on hotels and housing, not clinics. The clinic is where you measure. The building is where the change happens.
The cost curve
Ten years ago, building a longevity program meant buying the clinic. Testing needed a physician’s order and a lab visit. Monitoring meant a device in a medical setting. Follow-up meant another appointment.
Most of that has moved out of the building and fallen in price. In the US, a panel of more than 100 blood biomarkers is now sold direct to consumers for around $500 a year. A continuous glucose monitor is available over the counter for about $100 for two weeks. A ring that tracks sleep and heart rate variability costs about $300. A remote clinical team can review the results without the patient being in the room.
What still costs money is the interpretation, and the slow work of helping someone change how they live. That work needs people, and people need somewhere to meet. That is a job for an operator, not a laboratory.
The practical result is that a basic longevity program, one that measures and follows up, can now be priced like a gym membership rather than a medical procedure.
A worked example: a village in Portugal
For the past year I have been working on a model for an affordable longevity village on a nineteenth-century paper mill site in central Portugal. It is meant to test whether the argument above holds when you put real numbers on it.
The plan has 101 homes: build-to-order condominiums, membership residences and a small number of retreat rooms. A resident pays between €1,400 and €2,500 a month, with the home and the longevity membership included. The membership pays for testing and a care plan. The rest of the program is food, movement and the neighbors, which cost almost nothing.
Compare that with where the market sits now. A week of revitalization at Clinique La Prairie costs about CHF 32,000. A premium gym membership with longevity services can run above €3,000 a month. Those are products for the very wealthy.
I want to be honest about who €1,400 a month is affordable for. It sits inside the range of a typical northern European retirement income. It does not fit a Portuguese one. In 2024 the average Portuguese social security pension was about €645 a month, and half of pensioners received less than €462. Reaching that market will take public partners, subsidized housing or a smaller product, and anyone who says otherwise is selling something.
What makes the numbers work is the second point in this piece. The village breaks even at roughly half occupancy, fewer than 100 residents. It doesn’t need to market to strangers every month, because the residents are the members. The interventions that extend life are cheap. The containers we put them in are not, and a home is the one container people already pay for.
What breaks when you try it
Every operator who tries this runs into the same three walls.
Licensing. The moment a program does something medical, someone has to hold a license, and the rules differ by country. In Portugal, any unit that provides health care needs registration with the health regulator, the Entidade Reguladora da Saúde. A hotel cannot simply add a doctor to the spa menu.
Medical oversight and liability. The first question I ask any hotel planning a medical layer is who holds the license and the liability. The answer decides everything else: whether the medical partner is a tenant paying rent, a joint venture sharing revenue, or a contractor paid a service fee. Most of the failures I have seen came from leaving that question until after opening.
Staffing. Physicians interested in prevention are scarce, and scarcer outside capital cities. A rural village won’t have a full-time longevity physician on day one. Ours would run on a remote medical team, a visiting physician and well-trained local staff, and the program has to be designed for that from the start.
None of these is a reason not to do it. They are the reasons to plan the operating model before the architecture.
What a hotel or gym can do in the next twelve months
You don’t need to build a clinic to start. A hotel or gym operator can do most of this in a year:
Start with measurement. Partner with a testing provider so members get a baseline and a follow-up six months later. Nothing persuades like their own numbers moving.
Sell a membership, not a menu. A treatment menu brings guests in once. An annual program, with a fixed fee and a reason to return, is what paid the bills in Miami.
Put the medical layer under a contract. Bring in a licensed partner on a service agreement before you consider owning anything clinical, and settle who holds the liability in writing.
Train the people who already see your customers every week, the trainers, therapists and front desk, to explain the results and keep members on the program.
And measure the one number that matters: how many members renew.
The clinic will not disappear. It is still the right place for diagnosis and treatment. But the longevity business is moving to wherever people already live, stay and train, and the operators who own those places are better placed to win it than the clinics are.
