Our mission

Transforming mental healthcare, by unlocking the power of clinical data

So little is known about what makes mental healthcare successful and why. We’re changing that. Blending data science and deep clinical expertise, we’re learning about what helps people access the right treatment and recover. We’re using this knowledge to create cutting edge solutions that help prevent, treat and manage poor mental health. Our pioneering discoveries in mental healthcare are revolutionising how the world understands and treats mental health.

It’s time for a mental
health revolution

Our mission is to address the global rise in mental ill health by creating breakthroughs in how mental health is understood and treated, so that people everywhere have the opportunity to feel better.

Mental ill-health is on the rise


Despite global advancements in physical treatments, we know little about treating mental health conditions.

We’ve developed a
treat-data-improve cycle

Crucial learnings are available in every treatment session. We are the first to research patterns over many thousands of treatment sessions.

Data holds the key


Over 555,000 hours of therapy data have enabled us to break ground in the treatment of conditions such as depression and anxiety.

Unseen science.
Visible advances.
