What I do

Product ownership, Discovery, Delivery, UX, UI, Bullying AI — in a nutshell.

Guillaume Hubert

I'm Guillaume Hubert,
an hybrid Product Designer
& Product Manager based
in Belgium.

I've been in product for 10+ years — first as a UX/UI Design consultant, then as a Product Owner / Product Manager. I talk business impact with C-levels, dig into specs with engineers, iterate on UI with designers — and always fight for the user.

I'm currently building the app adios — try the demo — as a way to explore how AI is changing how products get built.

They worked
with me

  • Impact: Gui is goal-driven with a focus on continuous improvement. He gives everything to move forward the project he's working on.

    Problem Solver: When faced with a problem, he tries to understand it as thoroughly as possible and find the right solutions. And since he has strong analytical abilities, the solutions are often highly relevant! On top of that, he sees a problem as an exciting challenge.

    Maker: Gui has the ability (and the drive) to quickly make things concrete and move things forward. When we were brainstorming as a team or identifying a problem, Gui would very regularly come back with a solution a few hours or days later — without anyone having asked him for it.

    Methodical: He is highly structured, organized and disciplined. Combine that with his constant desire to save time and automate, and you get someone who is extremely efficient and gets an enormous amount of work done in a very structured way.

    Strategic: Gui quickly became my right-hand man at Ergonline — for all the reasons mentioned above, but also for his strategic capabilities. Very quickly he was able to analyze the competition, prioritize effectively, and make relevant proposals in terms of vision and growth.

    Beyond these highly professional qualities, Gui also proves to be a very human, transparent and loyal person.

  • I had the chance to work with Guillaume on several products, and he is one of the most impressive UX designers I've worked with.

    Guillaume combines strong creativity with sharp product thinking. He listens carefully, stays open-minded, and understands how to balance user experience with technical and business constraints without compromising the overall experience.

    Beyond his UX skills, Guillaume is simply a great person to collaborate with: thoughtful, collaborative, and always focused on building the right thing for users and the business.

  • What always stood out to me was how quickly he could turn a discussion into something concrete. During refinements, he'd sketch out flows on the fly, adjust them in real time, and get everyone aligned without slowing things down.

    This was even before AI prototyping tools were a thing, so it really comes down to his product sense and how he thinks through user journeys. That still holds up today, probably even more so.

    He's easy to work with, brings structure without overcomplicating things, and keeps momentum going.

  • I worked as a Product Owner with Guillaume in the role of Product Manager with a strong focus on design.

    What struck me most is his ability to represent and simplify the company's strategic direction by creating elaborate UI designs. This approach was essential in keeping the entire team as well as stakeholders aligned throughout the projects.

    Guillaume has an impressive ability to synthesize a complex request and deliver a thoughtful and effective user experience.

  • I had the chance to work with Guillaume for a few years, and from the start I found it impressive how he could simply take information, challenge what needs to be challenged, simplify everything and get moving to deliver impactful results. Projects become simpler as a result. A competent and talented profile!

  • Guillaume takes ownership of translating ideas for new features into concrete designs, bringing the visual concept of the solution to life. As a Product Owner, he keeps a strong focus on player experience, particularly for VIP players. I valued working with him and gaining deeper insight into player engagement and retention.

  • Really enjoyed working with Guillaume. He's thoughtful, focused on the user experience, and has a strong product management skills. A great colleague and someone I'd happily work with again.

    Definitely recommend him
