Our story
Built from one simple observation.
People can measure more about their bodies than ever before.
But very few know how their overall wellbeing is actually changing.
That simple observation became Longivy.

THE JOURNEY
Four countries. One observation.
Throughout my career as a physician, I worked in Switzerland, the United Kingdom, Greece, and the United States.
I met people from different cultures, backgrounds, and lifestyles, but I kept hearing the same questions.
"Am I actually feeling better?" "Are these lifestyle changes making a difference?" "What is really helping me?"
Medicine had excellent diagnostic tools. People had access to blood tests, health screenings, and wearable technology.
Yet many still struggled to understand how their overall wellbeing was changing in everyday life.
That question stayed with me for years.
THE IDEA
Wellbeing deserves more than one perspective.
I have always believed that understanding wellbeing requires looking at more than one source of information.
Doctors provide medical expertise. Wearable devices measure valuable physiological information such as activity, sleep, and heart rate.
But there is another part of wellbeing that only you can describe.
How you feel. How you cope with stress. Your energy. Your mood. Your confidence. Your daily habits. Your own experience.
These are not measurements that replace medicine or technology. They complement them.
Together, they create a more complete picture of wellbeing.
THE INSIGHT
The questions that matter.
Over many years, I noticed that certain questions consistently helped me understand how people were really doing.
Not only physically. But emotionally. Mentally. And in their everyday lives.
Those observations gradually evolved into more than 25 wellness markers.
Today, they form the foundation of Longivy.
A short check-in. One personal Health Score. One Wellness Level. A clearer understanding of your wellbeing over time.
THE CREATION
Why I created Longivy.
Longivy was never designed to replace your doctor. It was never designed to replace wearable devices.
It was created to help people better understand their own wellbeing.
By bringing together everyday reflections into one simple Health Score, Longivy helps people notice patterns that are often difficult to see in daily life.
As your score changes over time, you begin to understand something even more valuable.
What works for you.
Because wellbeing is personal.

When you connect the right signals, the bigger picture becomes clearer.

Dr. Kostas Pisios, MD
Kostas Pisios is a physician whose career has spanned wellness clinics, recovery programs, and preventive health settings across Switzerland, the United Kingdom, Greece, and the United States.
He founded Longivy with a simple belief: the most important aspects of wellbeing deserve to be measured, connected, and understood.
His work revealed a universal pattern. People often had information about their health, but little understanding of how the many factors influencing wellbeing interacted over time. Longivy was created to help bridge that gap. Not as a medical tool. Not as a diagnostic platform. As a wellbeing reflection system designed to help people see their own patterns more clearly.
