About us

ARCHI is a two-person product design studio.

We design products, we write code, and we ship features. Real ones: merged PRs, not prototypes gathering dust in Figma. Over the past three years, we've worked with 30+ founders on products that have raised over $1B from top-tier investors.

We named the studio ARCHI because what we do is closer to architecture than decoration. Architects decide where the load-bearing walls go. They design the structure everything else gets built on top of. That's the work we care about. Anyone can move a button. Very few people can decide what your product is, build the system that lets your team express it consistently, and leave behind something that holds up as the company grows.

Lately, our role has expanded past the canvas. Design is still our craft, but we now also write production code, prototype in real components, and build the AI workflows that let small teams move fast.

Need an MVP shipped before your next fundraise?
A product redesign that actually gets implemented?
A small fast team that does product strategy and pull requests in the same week, in or alongside yours? That's us.

"I had the chance to work with ARCHI on the launch of Qonto AI, and it’s a rare kind of collaboration. They bring a valuable dual quality: they know how to design within the tight constraints of a FinTech, rigor, trust, regulation while keeping a real sense of exploration alive. They consistently bring a sharp perspective on what’s being done elsewhere in AI. Given how fast the field moves, that constant awareness makes a real difference. I’d recommend them without hesitation."

"Working with ARCHI has shaped Well at every layer, from the AI agent surfaces to the core finance experience. Lucas and Sébastien combine the rigor a B2B FinTech demands with a sharp read on where AI is going, and they design at the speed of a founding team. The result is a product our customers actually want to spend their day in."

"One of the smoothest design collaborations I’ve had. They plugged into our team like insiders, picked up the product context fast, and pushed the thinking in ways we wouldn’t have gotten to on our own. What stood out most was the balance: strong craft and real opinions, but zero ego about it. They made the work better without making it theirs. Would work with them again without a second thought."

They ramped up incredibly quickly, developed a deep understanding of both our design language and our users, and integrated seamlessly into our development process. It’s rare to find a team that balances thoughtful design with speed and execution so effectively. I’ve been eager to work with them again ever since."
