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.

Defacto — Funding in seconds, not weeks
Defacto provides instant, flexible financing to businesses. We rebuilt the entire product and shipped a design system — transitioning Defacto from an API-first tool to a standalone SaaS platform. The goal was clear: reduce support tickets drastically by making every critical journey self-explanatory, so businesses could draw and manage financing without ever contacting support.

"ARCHI helped us go from an API-only focused product to a best-in-class self-serve web application. Thanks to their deep B2B expertise, they designed a whole new experience from onboarding to the core lending app, resulting in a strong improvement in customer satisfaction."
