Portrait of Lucas Simula

Updated March 2026

France-based Product Designer with a San Francisco mindset. Dedicated to minimalist aesthetics and functional clarity.
I focus on mobile products, SaaS tools, and design systems — the kind of work where a strong foundation changes every decision that follows.
I’m currently leading product design at chilli, an app empowering climate action, featured as App of the Day (opens in new tab) by Apple. I also co-founded Frame-ux, a design studio, alongside my brother.
