A product in use
A free health assistant on Telegram, an Android app that works offline, a connected watch, a dashboard for care teams and a public website, built and run by the same team.
Investors
Investing in support built with patients.
Coach Drépano builds Trévor, a free assistant for people living with sickle cell disease and other rare conditions. We talk with impact funds, foundations and institutional partners whose returns are also measured in health outcomes.
A clinical anchor
Trévor is co-designed at Geneva University Hospitals, with patients, clinicians and researchers. The project received a Fondation Dalle Molle award in 2021, and part of its development was funded by the HUG Private Foundation in 2022. An eight-week pilot study will open once the cantonal ethics committee has authorised it.
Free for patients
People living with the condition use Trévor at no cost. Resources come from donations, support programmes (coaching, workshops led by expert patients) and partnerships with institutions and patient associations.
Protected data
Hosting in Switzerland, precise consent before any use of data, deletion in a few taps, no data passed to third parties. These rules are part of the product and of its governance.
Patient-led governance
The project is led by a patient-researcher and the people concerned decide on features at every stage. This participatory design has been formalised and published.
A reusable engine
The same foundation serves sickle cell disease, Ehlers-Danlos syndromes and other rare conditions: one assistant, one app, one dashboard, transferable to other chronic conditions.
We gladly share the roadmap, usage indicators and governance framework, under a confidentiality agreement if needed. Trévor is under development: it is not a certified medical device and the clinical study is awaiting authorisation.
