UX/UI Design Agency Barcelona | B2B & SaaS

Why UX/UI design defines the success of your digital product

UX/UI design is no longer just aesthetics. It is the difference between a platform users adopt immediately and one they abandon before reaching the third screen. In B2B and SaaS products, where functional complexity is high and users are demanding, poor design translates directly into churn.

At Lucid_ we treat UX/UI design as a strategic discipline that connects user research, information architecture and visual design to create interfaces that work , for the user and for the business. We work with startups launching their first MVP, with scale-ups optimising their core product, and with large corporations that need to scale their platform without losing coherence.

Our UX/UI design process

Every UX/UI project starts by understanding the real context: who uses the product, under what circumstances, with what goals, and what friction they currently face. From there we build iteratively and with constant validation.

User research and analysis

We conduct in-depth interviews, behaviour analytics and usability tests to map the real needs of your users, before a single pixel is designed.

Information architecture, flows and wireframes

We structure content hierarchies and user flows so that every key task is intuitive. Low and mid-fidelity wireframes let us iterate fast before investing in visual design.

Visual design (UI), interaction and design systems

We create accessible interfaces, consistent with brand identity and emotionally resonant. Our approach always includes a scalable design system: reusable, well-documented components that speed up development and guarantee consistency across every screen.

High-fidelity prototyping and validation

Before handoff to development, we validate solutions with real users. Interactive prototypes reduce ambiguity, identify problems early and demonstrate product value before a single line of code is written.

FAQ: Frequently asked questions about UX/UI design

What is UX/UI design?

UX (User Experience) design is the process of creating digital products that are easy to use, efficient and enjoyable. UI (User Interface) design handles the visual layer of those interactions: colours, typography, components and visual hierarchy. Together they form the discipline that determines how users perceive and interact with a digital product.

What is the difference between a UX designer and a UI designer?

A UX designer focuses on the overall experience: researching users, defining flows, structuring information and ensuring the product is usable. A UI designer works on the visual layer: defining components, colour palette, typography and the visual language of the interface. On complex projects both roles work in parallel and complement each other.

Do you work with companies outside Barcelona?

Yes. We have offices in Barcelona and Madrid, and we work remotely with clients across Spain and Europe. Our projects include companies from Spain and international clients. UX/UI work lends itself perfectly to a hybrid on-site and remote model.

Can you collaborate with our internal development team?

This is one of our specialities. We regularly work side by side with internal technical teams, providing detailed design documentation, structured UI components and interactive prototypes that eliminate ambiguity at handoff. We have experience with agile teams using Figma, Zeplin or Storybook.
