Clea 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, Simon was told he had Multiple Sclerosis. The prognosis was devastating: progressive symptoms, possible wheelchair use, and a future filled with uncertainty.
But after months of tests and specialist appointments, the diagnosis changed. It wasn’t MS. It was a severe form of chronic migraine.
Invisible. Debilitating. Often impossible for others to fully understand.
That experience exposed something deeper - the emotional toll of living with chronic illness in a system built around appointments, not the reality of everyday life between them.
Clea was created for people living with conditions like migraines, endometriosis, chronic pain, autoimmune conditions, fibromyalgia, and chronic fatigue syndrome - people who often feel dismissed, exhausted, isolated, or forced to constantly start over.
We believe ongoing support matters.
That’s why Clea provides dedicated Mental Health Nurse support between appointments, with counselling available when needed - designed to work alongside your existing healthcare team, not replace it.
Because living with chronic illness can feel incredibly lonely. And people shouldn’t have to navigate it alone.
