About Limneo
A threshold,
not an ending.
A private marketplace for the next chapter of psychiatry and psychedelic medicine.

The work behind every practice
Built around
what matters.
Every practice in psychiatry and psychedelic medicine began with someone who chose the harder path. They trained for years, took on regulations most people never see, and built a place where people who had run out of options could finally get better.
Sooner or later, every one of those practices reaches a threshold. The founder is ready to retire, relocate, or begin something new. Someone else is ready to carry the work forward. And in between are the patients who trusted that practice with something deeply personal.
The moment
of change.
In Latin, that threshold has a name: limen. It is the doorway you step across into a new space. In psychology, it is the exact point where change becomes real. In the brain, it is the moment a signal is strong enough to pass from one neuron to the next.
Thresholds are where things can be lost. A practice sold carelessly can lose its team, its reputation, and the continuity its patients depend on. Too many owners face that moment alone, on generic marketplaces built for car washes and restaurants, with no one who understands what they built.
Limneo exists so that no practice
crosses that threshold alone.
Our name
The threshold
to what’s new.
Our name joins limen, the threshold, with neo, the Greek word for new. It begins with limn, an old English word meaning to bring something clearly into view. That is our work: we bring each practice clearly into view for qualified buyers who understand this field, and we help it cross into its next chapter.
Our purpose
A space built
for this field.
We bring owners and qualified buyers together in a private, professional space built only for psychiatry and psychedelic medicine. We understand what makes these practices different: the licenses, the protocols, the payer relationships, and above all the patients. We work alongside licensed transaction professionals, so every transition is handled with the care and compliance it deserves.
Every listing, every introduction, and every conversation is guided by one question:
Will the care continue?
Because in this field, a practice changing hands is never just a transaction.
It is a new beginning for everyone it serves.
