JOYCO is a design and engineering studio working on brands, websites and digital products with clients all around the world. Based in Buenos Aires, Argentina.
JOYCO Studio is a creative studio working at the intersection of design, culture and technology. Founded with a strong focus on clarity and craft, the studio develops brands, digital products and visual systems that prioritize intention over excess.
Joyco is driven by designers, developers and creatives working collaboratively across disciplines. Each project is shaped through close teamwork, combining diverse perspectives and a common focus on clarity, craft and execution.
The studio doesn't only build for clients — it builds for the web. Its open-source projects are shaped by real client work and published for everyone to use.
Identity, visual systems and creative direction — the brand layer the rest of the work is built on. Sazabi's identity and the graphic design behind Cerebral Valley's platform and live events were both built here.
Branding · Visual Systems · Graphic design · Creative Direction
Sites and portfolios designed and engineered by the same team, with interaction and performance treated as part of the design rather than a pass afterwards.
Web Design · Front-End Development · Interaction · Performance
Product interfaces and design systems for software teams. Sazabi, an AI-native observability platform, and Cerebral Valley are both ongoing design-engineering partnerships across product and platform.
Digital Products · Design engineering · Product · Design Systems
Real-time work built for the browser. Rampant's iconic ring was optimized to run across video and web; Johanna Arrieta's portfolio pairs shader work with illustration.
3D · WebGL · Illustration
Libraries, tooling and experiments shaped by the studio's real-world process and published openly, so other teams can move faster with them.
Open Source · Tooling · Experiments
A company needs a brand identity and visual system built from scratch, or an existing one rebuilt to scale — the work done for Sazabi and Cerebral Valley.
A team needs a website, portfolio or launch page designed and engineered end to end, with performance treated as a requirement — the work done for Andrés Briganti, Johanna Arrieta and Rampant.
A software team needs product interfaces, design systems or design engineering, and wants designers and engineers working as one group — the ongoing partnerships with Sazabi and Cerebral Valley.
A project needs real-time 3D, WebGL or heavy interaction on the web — the Rampant ring runs across both video and web.

Sazabi is an AI-native observability platform: you ask production what broke and it answers, instead of handing you dashboards. JOYCO gave that idea a public face at the level of what the team is building, a brand and a site that make a chat-shaped product legible to engineers in seconds and give Sazabi a system to keep publishing with.

Anomaly took mountain bikes to Antarctica. JOYCO built the visual identity and the trailer that announced it: hand-drawn lettering, spray-paint marks and 3D props cut against the real footage.
