What you gain from great UX/UI design

  • Your website stops being a brochure and starts converting: Constance Hotels increased conversions by 80% in twelve months and improved load times by 26%.
  • Marketing can publish without breaking the design: En Sector Alarm we built a design system with reusable components, and teams in each country started launching changes without waiting for development.
  • The redesign doesn't wipe out your search rankings: In DEACERO the UX and SEO teams worked in tandem, with the structure decided before launch rather than after.

How to know if you need to redesign your website

Your website looks good but doesn't generate leads. Sales gets calls from people who couldn't find what they were looking for and called out of desperation.
The technical buyer can't find the product data. The filters don't match how products are selected, and the spec sheet PDF is four clicks away.
Every change has to go through development. Marketing can't set up a new page without opening a ticket, so stop trying.
You've never checked if your website is accessible. It doesn't work with screen readers, keyboards, or sufficient contrast.

OUR PROCESS

Your UI/UX design service, step by step

01

Research

We start with who uses your website and what they come to do: compare, validate, or repeat an order. We look at analytics, heatmaps, and session recordings before forming an opinion on the design.
Deliverable: user experience audit with issues prioritized by business impact.
02

Design and validation

We design the architecture, flows, and interface, and test them before building anything. We validate with users or A/B testing, not with opinions.
Deliverable: navigable prototype, design system with reusable components, and applied accessibility criteria.
03

Implementation and measurement

We oversee the implementation to ensure the design makes it to production intact. Afterward, we measure conversion, speed, and behavior, and continue to make adjustments.
Deliverable: implemented design.

Web accessibility

An accessible website is one that anyone can use: whether with a screen reader, keyboard-only, or by users with low vision or color blindness. In industrial B2B, this isn't just a detail: some public tenders and purchases require it by contract, and buyers will abandon a site if a form cannot be completed without a mouse.

We audit against the WCAG 2.1 standard: contrast, visible focus, keyboard navigation, heading hierarchy, forms, and alt text. We provide you with a list of issues ranked by severity, with the specific fix for each, separating design-related fixes from development-related ones.

Why UX/UI design matters to every department

Here is how the day-to-day changes for each team when a website is designed for its users:

Sales

We get fewer calls from lost users and more requests from people who have already chosen their product. The conversation starts with the quote, not with "I couldn't find anything."

IT/Technology

A design system with reusable components reduces maintenance and ad-hoc requests. At Sector Alarm, this cut launch times across all their countries.

Marketing

Launch new campaigns and pages without breaking visual consistency or needing extra help. Plus, track which design changes actually move the needle on conversions.

Product

Heatmaps and session recordings show exactly what people look at before making a decision, and that data helps organize your product pages and catalog.

It's not about how it looks, it's about who it's designed for

"Having a pretty website isn't enough to make sales. The ones that work start with a different question: who is going to use this and what task are they trying to solve? That's where the architecture comes from, and that's where the interface follows."
