Digital Health Companion designs, implements and operates community-inclusive digital health platforms focused on rare and chronic diseases. We co-develop products with patients, families and clinicians to improve care, research and real-world evidence while preserving user data ownership and privacy.

Our flagship one4 platform connects patients, clinics, study sites and research partners through an end-to-end encrypted, federated architecture. Key offerings include the one4 app (Duchenne care companion) and Carisma® (SMA companion).

We partner with patient associations, healthcare providers and industry to enable pseudonymised real-world data for research while keeping ownership with patients.
