The missing piece in your team

Most product teams have the same problem: strong engineering, no UX & UI design capacity. Deadlines slip, the product looks unfinished, and design debt piles up.

We step in as your senior design team: fast turnaround, direct access, no overhead. Based in Barcelona, 15+ years designing products for startups and scale-ups across every sector.

Stuff we handle

Branding

Logo, visual identity, typography, and colour system. All documented in a brand book any designer or developer can apply without ambiguity.

Heuristic Analysis

The usual starting point for redesign projects. We audit your product, identify the real usability and conversion problems, and hand you a prioritised plan: what to fix first and why.

UX Design

Information architecture and user flows that solve the product before visual design starts. Cheaper to fix on paper than after launch.

Product Design

High-fidelity interfaces for web and mobile. Delivered in Figma with component states, annotations, and build-ready specs. Developers start without questions.

App Design

iOS and Android. We follow Apple and Material Design guidelines but with your own identity. Navigable prototypes ready to validate before writing a line of code.

Development

React, Next.js, Astro, and Framer. Marketing sites, dashboards, and web apps with auth and integrations. Clean code, well-structured, easy to maintain.

Sounds Market — UX & UI, Website
The quality leap we noticed in our website design since we started working with Atico3 is huge, it marked a before and after for Sounds Market. We went from having an impersonal website with a very outdated UX/UI design to a modern, professional site that perfectly conveys our brand values.
