About Us
Changing the Way the World Measures Stress
Felix was born from a simple idea: if we can’t measure stress accurately, we can’t manage it. Our team of scientists, technologists and behavioural experts set out to change that.
We created a platform that makes stress measurable, visible, and actionable — at scale.
From corporate teams to clinical trials, Felix is now helping people understand their emotional state like never before.
