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.

Designers, engineers and 3D artists work as one team, with no project managers or HR in between: clients talk directly with the people doing the work.

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.

Capabilities

  • Brand Identity & Visual Systems

    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

  • Website Design & Front-End Development

    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

  • Digital Products & Design Engineering

    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.

  • 3D, WebGL & Real-Time Interaction

    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

  • Open Source

    Libraries, tooling and experiments shaped by the studio's real-world process and published openly, so other teams can move faster with them.

When to use JOYCO

  • 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.

  • Someone is looking for JOYCO's open-source libraries, tooling or experiments — https://github.com/joyco-studio, https://lab.joyco.studio and https://hub.joyco.studio.
