Web Design • UI Design • Design Systems • Prototyping
We design digital products for brands where every click is worth millions. From UI through design systems to prototypes. We create designs that can be measured in conversions, development time, and customer satisfaction.
Design that doesn't sell an impression. It sells results.
We design digital products for brands where every second and every click are worth millions. We combine user research, business goals, and your brand's visual language into interfaces that reduce bounce, increase conversion, and scale across markets.
One source of truth for product, marketing, and development.
When a brand has 5 websites, 3 applications, and 12 designers, chaos is a matter of time. We build design systems that unify components, colors, typography, and rules across the entire organization, from Figma to code. The result: faster development, consistent branding, and predictable costs for changes.
Bullets:
Test the product before you start building it.
An interactive prototype will tell you in two weeks what you would otherwise find out after six months of development and hundreds of thousands of euros. We validate the product vision on real users — from clickable mockup through usability testing to data that shift the decision from "I think" to "I know."
Bullets:
Brands with a turnover of 10M€+, where a 1% conversion means hundreds of thousands annually.
Complex interfaces where UX determines retention and upsell.
Organizations that need to unify design across products, countries, and teams.
Banks, insurance companies, healthcare, and utilities, where design must handle complex products, compliance, and customer trust simultaneously.
One-stop shop is a comprehensive solution for all your online project needs. Starting with a stable content management system, through sophisticated UX testing, web and application development, B2B solutions, artificial intelligence products, to a wide range of online marketing services.
Every project starts with the question "What numbers should this design change?" Conversion, AOV, retention, time on task. We don't start without KPIs, because without KPIs you don't know if it worked.
UX research, heatmaps, usability testing, A/B tests. Design at ui42 is argumentatively defensible before the board and backed by data.
UX researchers, UI designers, frontend developers, and analysts under one roof. No "deal with development," we refine the design all the way to production
Our oldest clients have been working with us for over 20 years. This is not a coincidence, but the result of the fact that design at ui42 is not a one-time deliverable, but a long-term collaboration.
We are not building 20 ad-hoc pages. We are building a design system that will last for 5 years and scale across products, countries, and teams.
