AIOS is a telehealth startup building the first AI-embedded operating system for clinics. It operates as Fella Health in the US and Bolt Pharmacy in the UK, with GLP-1 weight management as its flagship product. Because these are prescription medications requiring clinical oversight, every patient completes a multi-step enrolment before their first order — including uploading prescription evidence and a full-body photo for BMI assessment, screened by AI before a clinician reviews.
