Hocoia

When the doctor is too far away, one person in five gives up on care. At Hocoia, I design the apps and the mobile practices that go to them.

Role
First employee, founding designer and senior product designer
Team
With the PO, the CTO and two development teams, in-house and external
Scope
Two apps, the design system, the vehicle layouts
Period
Since June 2022

In short

The challenge
Fitting a medical practice into a truck, and a whole care journey into a single app, for patients who struggle to access care.
The approach
Journeys designed for each role, including patients with no phone or email, and a design system to keep everything consistent.
The result
Nearly 10,000 patients seen, and 4.86/5 satisfaction from 575 respondents.

The problem

In France, seeing a doctor has become an uphill battle for millions of people. About 6.4 million have no regular doctor. Outside the big cities, an appointment with a dermatologist can take up to nine months. And the less people see a doctor, the more their health declines.

The field surveys I ran confirmed it: about 20% of people give up on care entirely when the appointment is too far away, in distance or in time. It isn’t a lack of will. The system has become out of reach.

So Hocoia brings the practice to the patient: mobile, connected medical units, as close as possible to where people live. When I joined, a first identity existed, created with the Manaka studio in Lyon. But there was no app, no design system, and little knowledge of the people we were serving.

When patients can’t reach the practice, the practice comes to them.

The constraints

Everything happens in the field: the experience has to work for the people on site, patients, healthcare professionals and reception agents alike. Many patients are comfortable with digital tools, but some are elderly or far from them, and others are anxious about a remote consultation. Caregivers on board (nurses, midwives, radiographers) work in a tight space and need to be fast and accurate. And healthcare is a heavily regulated field: every design choice has to work within those rules. These constraints shaped everything else.

The method

I started with research: patient surveys, listening to caregivers and clients, competitor analysis, mapping the friction points.

The product moves forward in sprints of about three weeks, each followed by a testing phase. The team brings together the PO, the CTO and two development teams, one in-house, one external. The PO and the CTO prioritise features, and I join those trade-offs when some needs become more urgent. Work is tracked on a kanban board.

The patient journey

Some patients have neither a mobile phone nor an e-mail address. So the app had to offer two paths, which meet under the reception tent.

  1. 01Booking

    With a phone or an e-mailSigns up and books online

    Without phone or e-mailCalls the secretariat, which creates the account and sets the appointment

  2. 02Before

    With a phone or an e-mailFills in a questionnaire tailored to the exam

    Without phone or e-mailFills in the questionnaire by phone, with the secretariat

  3. 03Arrival

  4. 04Consultation

The product

I have worked on the UX and UI of the app from the start, as part of Hocoia’s tech team.

The app, used as a SaaS by clients such as hospitals, hasmore than five roles, each with its own tools. I also design custom features for these clients.

  • Patient online booking, pre-consultation questionnaires, a secure account for their documents
  • Secretariat consultation slots, accounts and appointments
  • Reception the day’s schedule, check-in
  • Healthcare professional identity checks, shared questionnaires
  • Doctor live or asynchronous teleconsultation, medical form, prescriptions, reports, triggering the payment
  • Administration a space for administrators and clients, such as hospitals

I also designed the video-consultation module, a full application that can run on its own or connected to the Hocoia app. It automatically collects readings from the connected medical devices: temperature, oximetry, spirometry, dermatology, ultrasound, stethoscope, heart rate, blood glucose, uric acid, among others.

To hold it all together, I built the app’s design system from scratch, on my own, with Figma, Claude Code and ChatGPT: foundations, components and rules, accessibility (WCAG) included, a base the product can grow on without starting over on every screen.

The reception agent’s journey

Reception happens under a tent at the back of the vehicle; only the consultation takes place on board. The reception agent had no place in the app. Here is their day, before and after.

  1. 01Preparing the day

    BeforeA paper list or an Excel file, quickly outdated

    With the appThe day’s schedule, always up to date

  2. 02Welcoming

    BeforeThe agent doesn’t exist in the system

    With the appChecks the patient’s identity and records their arrival

  3. 03Alerting the team

    BeforeImpossible without interrupting the consultation

    With the appA discreet notification, with no personal data

  4. 04Handling a no-show

    BeforePhone calls to the secretariat, then waiting for the consultation to end

    With the appThe reason is recorded, the team can see another patient

The decisions

Leave no one behind

What we saw
Some of our patients have neither a mobile phone nor an e-mail address.
The choice
Dedicated journeys: booking by phone, on-site staff to help patients who struggle, and results on paper, on site or by post.

Bring the reception agent into the system

What we saw
The reception agent didn’t exist in the system: they worked on paper, with no link to the team on board.
The choice
The request came from the field. I set up this role with the PO and designed the whole arrival journey, error cases included, after consulting reception agents, the secretariat and healthcare professionals. It went through several iterations before testing, then production.
What it changes
The agent sees the day’s schedule, always up to date. The medical team knows when to prepare the next appointment, handle an absence or see another patient. The reason for an absence is recorded, so the team can see how many patients didn’t come and why.

Limited rights, a discreet notification

The choice
The reception agent has no access to health data and only sees what is needed to welcome the patient. When they record an arrival, the notification that alerts the team shows no personal data.
Why
Reception happens outdoors, under a tent, and the notification arrives during a consultation: it must neither expose the patient nor interrupt.

The vehicles

On several Médicobus and on the Mammobus, I worked on the layout of the medical practice, almost as a duo with the plan designer, starting from patients’ needs. Each project was a little different. The plans then went to the partners who build the vehicles. Alongside, I worked with clients on the vehicle wrap, often custom-made, and followed its installation to make sure the result was right. That’s where my work comes together: the vehicle and the app live in the same space.

The Mammobus was the most demanding project. Mobile mammography units are usually huge trucks that need a heavy vehicle licence and can’t go everywhere. Ours, presented as the smallest mobile mammography unit in the world, weighs 3.5 tonnes and can be driven with a standard car licence. It had to fit a mammography unit, an ultrasound scanner, two workstations and an access ramp, without sacrificing patient comfort or caregiver ergonomics.

Today

In 2026, I proposed bringing in the Graphéine agency to redesign the brand identity. The marketing team led the project, and I worked on it with them, all the way to the vehicle livery. Building on this new identity, I created a new design system, and the app is now being updated to match.

The result

Nearly 10,000 patients have been able to see a caregiver thanks to these mobile units, often in places where they would not have had access to one otherwise. Today they offer screenings and consultations in dermatology, cardiology, respiratory health, women’s health, check-ups, and mammography with ultrasound. The Mammobus travels across France and carries out screenings regularly, with very positive feedback from patients.

And according to an MNT article from September 2025, residents say that without the Médicobus they would not have gone to see a doctor.

The Médicobus in front of investors

The Médicobus, whose interior layout and livery I designed, was presented on “Qui veut être mon associé?”, the French version of Shark Tank. Anthony Bourbon and Jean-Michel Karam invested in Hocoia, and the show came back to see the company a year later.
