I built Gisello because I needed it
and could not find it.
In 2025 I was the patient. I had a folder of PDFs from clinics in four countries, each one friendly, each one a different price for what looked like the same thing, and no way to tell which of them fitted my file. I had a corporate job, two languages and nine years of building operations at scale, and I still could not answer the only question that mattered: where should I go, and why?
The more I looked, the clearer the structure became. Records don't travel; I was re-typing my own history into web forms. Agencies are paid by the clinics they recommend, so the shortlist is a sales list. Scans and aftercare at home are nobody's job. And when something goes wrong abroad, the patient is the only person in the room who has read every document. None of this is anyone's fault. It is simply how the industry has been wired for twenty years.
Nobody should have to be their own medical coordinator in a language they don't speak.
Gisello is the company I wanted to hire. You pay us, so we work for you and no clinic pays us a commission. A nurse Care Advisor is your one person from the first call to the follow-up at home. Your record travels with you, encrypted, and no clinic sees anything until you say yes. Before any clinic is named, a doctor signs a brief that explains your situation in words you can hand to your own GP. The AI, Gina, does what software should: it remembers everything, drafts the paperwork, and answers at three in the morning. It never gives medical advice and never chooses your treatment. That stays with you and your doctor.
We start with fertility, for patients from the UK, in clinics in Czechia, Spain, Greece and Cyprus, because that is where the gap between what patients pay and what they get is widest, and because it is where I started. Aesthetics, dental, orthopaedics and bariatric care follow, each with its own clinical board. The promise is the same for every one of them: you will know what is happening, you will know what it costs, and you will not be alone.

Three places that shaped
the operator behind Gisello.
A small German city that takes its institutions seriously. I grew up assuming systems were meant to serve the person in front of them, and noticing, early, when they didn't.
Nine years in corporate roles across Germany, Luxembourg and the UAE. Amazon taught me that the customer's experience is an operations problem, that every promise needs a mechanism behind it, and that scale is earned one journey at a time.
A city built on people arriving from somewhere else, with a health regulator that takes cross-border care seriously. Our patients come from the UK first, then the Gulf and German-speaking Europe. Dubai sits between them.
