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.

Immortal Game — Chess, but better
Immortal Game is rethinking online chess — a market of over 20 million daily games — by layering web3 assets and a next-generation gaming experience on top. We shipped new play modes that drive session time, a mobile app that brought the product to where most players actually are, and a game analysis mode that gives competitive players a reason to stay. Every surface we built was designed to move users from casual games to invested, returning players.

"Those guys designed our entire mobile app from scratch and supported us on some of the most complex features of our platform. Over a year of collaboration, they’ve become a real extension of our team. Rigorous, fast, and always pushing the craft forward."
