Commissioned by Sésame, a non-profit focused on affective and relational education, Doko is a mobile app designed to guide teenagers through sexual health education by creating a safe, engaging, and professionally supervised space.

The core challenge: rethink how sexual education is delivered to adolescents, moving away from a one-size-fits-all institutional approach toward an experience that meets teenagers where they actually seek information on their phones, in formats they trust.

In collaboration with Carla Deronzier, Maxime Coette, Nicolas Raherison, and Aline Delaunay.

user research

Research started broad, with a strategic framing phase aimed at defining the target user panel, mapping their unmet needs around sexual health information, and identifying viable product opportunities.

We distributed a survey that collected 280 responses, followed by focused sessions with two distinct groups: parents and young adults. Key findings that shaped the product direction:

  • Existing solutions embedded in the school system were widely perceived as inadequate

  • There is a strong, unmet demand for reliable and accessible documentation

  • Preferred formats skewed toward Instagram-style content, short-form video, and dedicated apps

wireframe & prototype

Based on research outputs, the app was structured around three core product pillars:

Quiz module: tracks personal progress across knowledge categories, making learning feel iterative and self-directed

Video space: categorized educational content including live Q&As on top-voted questions, myth-busting segments, expert interviews, and firsthand testimonials

Community FAQ: a moderated space where teenagers can post questions, upvote what matters to them, and receive validated answers from healthcare professionals (sexologists, psychologists)

Every piece of content on Doko is reviewed and approved by Sésame’s educational team before publication, ensuring medical accuracy and age-appropriate framing without compromising the app’s tone.

Beyond the teenagers themselves, we designed a companion landing page targeting parents addressing adoption friction at the household level by clearly communicating the product’s editorial framework, professional oversight, and safety guarantees.

Trust, in this context, is a product feature: without it, the app never gets installed.
