How to choose the right UX/UI agency

When evaluating Spanish UX/UI agencies, consider:

Research and strategy capability – Determine whether the agency offers user research, testing, and strategic UX consulting alongside execution, or focuses primarily on visual design and prototyping.

Portfolio and domain expertise – Review published work to assess design quality, problem-solving approach, and experience in your sector (fintech, e-commerce, SaaS, consumer apps).

Process and methodology – Understand the agency’s design process, tools (Figma, Sketch, Adobe XD), and how they integrate with development teams and stakeholders.

Team structure and scale – Match agency size to your project needs. Boutique studios offer hands-on craft; larger agencies provide capacity for complex projects.

Testing and validation – Ask about usability testing methods, A/B testing capabilities, and how design decisions are validated with real users.

Language and communication – While most Spanish agencies work in English for international clients, confirm language capabilities and cultural fit for your project.
