Our story
Sleep expertise, now accessible to all travelers.
Where it began
It all began at the Institut Médical du Sommeil in Paris.
In our practice, we worked with people facing exceptional demands: elite athletes, executives, frequent international travelers, and patients for whom jet lag was a real difficulty.
What we saw
They all asked the same question: how can I arrive feeling well instead of spending the first days recovering?
We saw that advice to sleep on the plane or get daylight was not enough. Jet lag is more complex. Light at the wrong time, a poorly timed nap or unsuitable advice can delay adjustment of the body clock.
The method
AI can produce recommendations in seconds, but it does not by itself guarantee that they make sense in chronobiological terms.
We wanted to go further.
For months, we studied scientific models of the body clock, compared approaches, examined their limits and designed an algorithm to turn that knowledge into personal guidance.
For every traveller
Our aim was simple: make this expertise available beyond the few travelers receiving specialist support.
Why not let everyone benefit from it?
That is how Fuseo was born.Our scientific committee
Fuseo's method is based on published chronobiology research and on the team's clinical practice.
