Back to original languageAbout Bruno
You're developing a SaaS, from scratch or an existing version:
• your users are dropping off
• your product is complex to understand
• your MVP isn't convincing in demos
• your team is wasting time due to UX debt
• you have great AI tool ideas but struggle to shape them to convince
I turn these roadblocks into business leverage 🪄
I design clear, high-performing, conversion-oriented SaaS experiences.
From sales prototypes to scalable design systems, I structure your product to be understandable, desirable, and profitable.
Specifically:
→ MVP validated before development to secure the sale
→ Interactive prototypes used in sales closing
→ Design system to reduce debt and accelerate squads
→ Intelligent integration of AI into truly usable interfaces
Recent examples:
• Launch of an AI coaching platform with a voice interface → sale validated before build
• AI app at Bloomflow → deals validated with clients before build
• Implementation of design systems in complex environments (Ubisoft, B2B SaaS) → up to 1h saved on delivery from specs to build
What I bring:
Strategic clarity.
Fast execution.
Long-term product vision.
If your product needs to convince, scale, or integrate AI without losing users, let's talk.

Bruno was top-notch. We received an impeccable quality design system. Bruno was proactive in his thinking and discussions, which allowed us to move faster and go further than I had hoped. I hesitated to hire a designer with a lower daily rate, but Bruno is very efficient and I was very pleasantly surprised by the quality/price ratio of his service.
