Sahha's technology is backed by cutting-edge research in digital phenotyping
Sahha is currently involved in internal and external research projects backed by leading universities and research organisations.
Involved in our internal research projects across a diverse range of ages, genders and nationalities.
Trained on 100,000+ Individuals
Our models are trained on hundreds of thousands of people around the world.
50K+ Clinical Samples
Our internal projects collected tens of thousands of clinical samples in order to build the foundations for our predictive models.
Our current methodology is based off of the current literature, there are many papers existing today that show how digital biomarkers and behaviors are used to predict mental health assessment tools used by clinicians. Academic research papers highlighting how digital biomarkers and behaviors can be used predictors for clinical mental health assessments
