We’re not just here to offer therapy.

We're here to change how mental health care works for you, and everyone living with chronic illness.

Cleo is rethinking the system, building a more proactive, ongoing model of care that supports your mental health before crisis hits.

From waiting for things to get worse, to finally getting ahead of it.

Cleo was founded by Simon Greally and his partner Alice - partners in life and now in purpose. Simon, a former professional athlete turned health tech leader, knows firsthand the invisibility, misdiagnosis, and mental toll that chronic illness brings.

At 31, he was told he had Multiple Sclerosis. The prognosis was devastating: progressive symptoms, likely wheelchair use, a future full of uncertainty. But six months and countless tests later, the diagnosis changed. It was not MS. It was a severe form of chronic migraine. Silent. Invisible. So intense it often left him unable to walk, speak, or function.

That moment cracked everything open - the grief, the fear, and the mental toll of being chronically unwell in a system that does not see you. Alice stood beside him through it all. And together, they realised something needed to change.

Cleo is for the millions of Australians living with chronic conditions who have felt dismissed, misdiagnosed, or just plain exhausted. It is therapy that actually fits around your life. Trauma informed, subscription based, and matched to your condition and your capacity. No clinics. No waiting rooms. No need to start over.

Every therapist in our network is experienced in chronic illness and backed by a Advisory Board that ensures our care stays ethical, safe, and evidence based.

Because chronic care should always include mental health care. And no one should have to go through it alone.

Built with purpose. Led by therapists who understand.

Our Purpose: Our purpose is to change the way the world cares for people with chronic illness by making therapy accessible, routine, and part of everyday life.
Our Vision: To make long-term mental health support for people with chronic illness as normal as going to the gym, starting in Australia and expanding worldwide.
Our Mission: Our mission is to reimagine mental health for people with chronic illness so they feel seen, understood, and in control, with therapy that fits everyday life and builds a new global standard of care.
Because support for your mind should work like a gym membership, consistent, ongoing, and part of life.

You don’t have to explain everything. We already understand.

Cleo was born from personal experience, years of misdiagnosis, invisible pain, and the mental toll that comes with chronic illness. Built with the support of someone who lived it beside him every step of the way, Cleo is designed for people who want care that truly sees them.
