About Sovereign Systems PBC
Sovereign Systems is building a patient-owned health record that brings labs, genetics, wearables, and clinical records into one encrypted place, with the encryption key held by the patient. The company holds only ciphertext, so it can’t read, sell, or identify anyone’s records: privacy is built into the architecture, not promised in a policy.
