Case study
Steady traffic, but revenue was leaking through poor free-to-paid conversion and high onboarding churn. By re-aligning the value proposition, shortening time-to-value and redesigning a key feature page, we delivered measurable growth within weeks.

Testimonials
Very concrete, relevant, results-oriented support
He supported us on several projects, and we notably collaborated with him on Flokon’s user interface analysis, customer journey optimization and website sales funnel optimization.
He is a humane, multidisciplinary, creative person who can think differently. He is extremely pleasant to work with and always knows how to adapt to our needs.
In our early days, he adjusted his service offering to propose very concrete, relevant, results-oriented support.
I recommend him 200%. It’s rare these days to work with someone so professional, competent and caring.

We couldn’t be happier with the results
I’ve been working with Jean-François for over 3 years on a SaaS platform, where he leads our UI/UX, and we couldn’t be happier with the results.
He’s a pleasure to work with. Very human, positive energy, easy to talk to, and always open to hear others’ opinions and insights.
He has earned the full trust of our team and has repeatedly risen to our most difficult challenges and shown a remarkable ability to adapt as our platform and needs continue to evolve. Highly recommend.
Charles-Érick’s support went far beyond my expectations
In the few words this space allows me, I can say that Charles-Érick’s support went far beyond my expectations. Creative, quick-witted and incredibly well organized, he goes well beyond simple user experience thinking. He is a deeply human person, and it shows directly in his work. I recommend him with my eyes closed.

Three things: we re-aligned the homepage value proposition around the user outcome, we simplified onboarding so users reach their first "Aha!" faster, and we redesigned the high-intent feature page based on behavior data.
