How to choose the right UX/UI agency
When evaluating Belgian 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 interface design and visual implementation.
Portfolio and domain expertise – Review published work to assess design quality, problem-solving approach, and experience in your sector (fintech, healthtech, enterprise software, e-commerce).
Process and methodology – Understand the agency’s design process, tools (Figma, Sketch, Adobe XD), and how they integrate with development teams and product stakeholders.
Team structure and scale – Match agency size to your project needs. Independent studios offer specialist focus; full-service agencies provide integrated capabilities including development and marketing.
Testing and validation – Ask about usability testing methods, A/B testing capabilities, and how design decisions are validated with real users and measured post-launch.
Language and communication – Belgium is multilingual (Dutch, French, English). Most agencies work across languages. Confirm language capabilities, particularly for international teams or multi-market products.
