Jus Mundi offers valuable tools for all actors in international law, from AI assistants to document research and correlation, and professional search. A French company with a global reach by definition, I collaborated closely on its brand creation and marketing design products. Supporting them since their Series A, I also contributed to recruitment, the implementation of design processes, and productivity tools.
Jus Mundi: The Core Brand
Following a brand audit, we reviewed the visual identity, with a new visual language while keeping the original logo. This informed a new webdesign structure and a unified Design System kick-start for both marketing and product. I supported this growth by helping on hiring, managing external partners, and establishing processes and templates for digital/print assets, enabling parallel team workflows.

A new Brand Family
I created identities for new ventures. Jus Connect, with its own illustration style and color palette, for which I delivered the first dedicated Product Design. Daily Jus, supporting its launch with an MVP WordPress template. Finally, I helped on the Jus AI logo and graphic style. This expansion was an exciting exercise of keeping/re-inventing graphic codes from the Jus Mundi umbrella brand

From 2022 to 2025, Jean-François and I worked closely together, and he quickly became someone I could count on for thoughtful, high-quality design across branding, marketing, and product needs. He shaped the Jus Mundi brand during an important stage of our growth, built the sister brand for Jus Connect, and supported a wide range of projects with calm, creativity, and impressive versatility. No matter how tight the timeline, he always approached challenges with clarity and a solution-driven mindset. He’s collaborative, reliable, and genuinely committed to improving how things are done. I would work with him again in a heartbeat.

I had the chance to work with JF when I was leading product at Jus Connect, and he was instrumental in helping us build the Jus Connect brand and product from the ground up.
We needed a modern identity that could still fit within a very traditional legal industry, not an easy balance, and he managed it perfectly. He helped us set strong design foundations, create a brand system that truly stands out and is remembered, and ensure all our product and marketing materials felt consistent and professional. What I appreciated most is that he understood our personas, which are very different from most tech audiences. He always asked the right questions and went beyond the brief to make sure the design reflected our market and users.
He’s creative, fast, and simply great to work with.
