Why this project matters

Supporting the most vulnerable, in the field

Outreach teams work with homeless people in difficult conditions. Before MANO, they had no suitable digital tool to track journeys, plan actions and share sensitive medical information securely.

Medico-social follow-up

Complete user record, encounter history, referral and procedure tracking. A tool designed for the field, usable on the go with or without connectivity.

Secured health data

HDS hosting (Scalingo), end-to-end encryption, restricted medical record accessible only to authorized healthcare professionals. Full compliance.

Selego has supported MANO as Fractional CTO for 5+ years - from MVP to national deployment

User record

Action planning
