The science behind it

Grounded in peer-reviewed science.

We’re bringing the same science used in clinical settings to everyday life.
While Raeva is not a diagnostic tool, our algorithms and actionable insights are based on clinical methodologies that prove the predictive power of wearables:

98%

accuracy predicting bipolar manic or hypomanic episodes (study conducted by Korea University College of Medicine)

92%

accuracy predicting panic attacks up to 7 days in advance (study conducted by National Taiwan University)

80%

accuracy predicting depressive episodes before symptoms begin (study conducted by National Taiwan University)
Sports research shows that biometric-guided training around sleep, HRV, and stress markers leads to greater performance gains and recovery. Raeva applies these methodologies to your daily data:

72%

accuracy identifying early signs of illness 1–5 days before symptom onset (studies by Stanford University & Scripps Research)

11.7%

VO2 peak improvement over 9 weeks using heart rate-controlled periodization (study cited in Frontiers in Physiology)

17.4%

increase in Time to Exhaustion (gain in athletic stamina and endurance) using biometric-guided training intensity (study cited in Frontiers in Physiology)
These figures reflect published findings from peer-reviewed studies applying machine learning to wearable biometric data. Raeva applies these validated approaches to your personal data to power personalized wellness, sleep, and recovery insights.

Our Founder’s Vision

Born from a personal quest to train smarter

Raeva isn’t built by people looking at data from a distance. It’s built by people who lived the problem.

Liz Hixon

Raeva Founder
Raeva stemmed from frustration with my own athletic performance. Even on light and easy runs, my heart rate consistently stayed in the max zone. A cardiologist gave me a clean bill of health, but confirmed I needed to focus on lower-effort workouts. Meanwhile, my wearable was suggesting longer, faster runs: generic recommendations that ignored my actual metrics.
To improve performance and recovery, I knew I needed to build my training around my own body.
I began synthesizing my wearable data with AI, adding context like mental health fluctuations, medications, and diet. The result was personalized training and recovery guidance that finally delivered real progress.
At Raeva, we know that optimizing physical performance isn’t about working harder every day, but matching your training intensity to your body’s capacity. True progress starts with daily lifestyle, stress levels, and nervous system balance. Raeva translates your wearable biometrics into actionable, personalized insights, so every workout moves you forward.
