01
One designer, end to end
You get me — not a junior, not a project manager. From research to handoff, single point of accountability.
Senior Product Design Partner for decisions that compound.
I'm Lucas Rappart — a Product Design Partner working remotely with founders, design leads, and executive teams across Switzerland, Europe, and the US. Strategy, IA, hi-fi design, systems.
Get in touchSelected clients
Fortune 500 enterprises to Series A founders, across healthcare, hospitality, media, marketplaces, and climate tech. I help teams ship hi-fi product surfaces, set up design systems that compound, and translate complex workflows into clear customer-facing experiences.
How I partner
02
Founder-fluent
I've worked with 30+ founders. I speak product, growth, and roadmap — not "design speak".
03
Long-term, not project-based
The best work happens in continuity. I optimize for relationships that last quarters, not sprints.
WHAT CHANGES
What changes when we work together.
WITHOUT A PARTNER
WITH A PARTNER
Your roadmap looks busy but nobody on the team can defend the prioritization in one sentence.
A sharp problem statement and a 90-day plan you can defend to the board.
UI shipped twice. Every new designer rebuilds the same components from scratch.
A design system that compounds — new designers ship consistent work in week one.
Three-month rework cycles every time you ship a major flow.
Hi-fi flows tested in two-week sprints. Edge cases surfaced before engineering commits.
Design handoffs that take half a meeting to translate to product and engineering.
Executive-ready briefs in the language your CEO, PM, and engineering lead already share.
