UX and UI Design Agency

Turning complex challenges into clear, elegant experiences.

UX and UI design agency for complex digital products

Vigo is a UK UX and UI design agency. We design customer portals, SaaS platforms, configurators and data-dense tools, and we stay on after launch to measure whether the design worked.

From data-heavy dashboards to visually rich content platforms, we focus on making complexity simple and interaction effortless. Our team blends research-driven UX thinking with refined visual design, ensuring every decision serves both the user and your business goals.

We work in close collaboration with you, iterating rapidly to test and validate ideas. The result is digital products that are not only beautiful, but deeply intuitive and built to perform across every device.

What good UX and UI design changes

Every UX and UI project starts with a baseline and ends with a comparison against it. These results come from a legacy estimating platform and an e-commerce configurator, each measured against the interface it replaced.

UX concept, page layouts and measurement in one team

We don't start with screens. We start with the people who will use them: stakeholder workshops, observation sessions, journey mapping and competitor benchmarking. That research decides the structure of every page before anything is styled.

From there we produce UX concepts and page layouts, test them with real users, and turn the winning direction into production-ready Figma designs on a component library your developers can build from. After launch we compare the new product against the old one on the measures agreed at the start.

What you get from a UX and UI project

Each deliverable builds on the one before it. Research decides how every page is structured before anything is styled, and the design system means the layouts users tested are the ones your developers build.

UX research

Stakeholder interviews, observation sessions, journey maps and Jobs to be Done analysis.

UX concepts and page layouts

Interactive wireframes, user flows and annotated prototypes, tested head to head with users.

UI design and design systems

Component-based systems in Figma, including React design systems for engineering teams.

Measurement and optimisation

Before-and-after benchmarks on task time, clicks and preference, plus UX audits and conversion work.

Where our UX and UI work is strongest

  • Customer portals and self-service journeys where users need to find, change or buy something without calling support. Catchbox's redesign was built to reduce reliance on phone and email support.

  • Data-dense interfaces for expert users, such as estimating tools where engineers view thousands of line items at once.

  • Product configurators and complex catalogues, including 3D product assets so buyers see their choices.

  • Legacy platforms that need a modern interface without a rebuild.

From insight to impact

Our UX and UI design process doesn’t end with the handover. We help teams embed design systems, prepare for implementation, and gather feedback for ongoing optimisation.

The outcome is not just a polished design it’s a living, evolving experience that adapts as your users and business grow.
