Top UX design agencies to work with in 2026

You have a few seconds to convince a user that it's worth staying. Those few seconds create the first impression and represent the moment when the user decides whether your product is trustworthy or whether it's time to move on and look for a solution elsewhere. Behind those few seconds is, more often than not, the work of a UX/UI team that thought through every detail before the user pressed the first button.

‍

Finding the agency that can deliver exactly this level of rigor requires a serious selection process. To simplify this step, we've put together an analysis of the best product design and UX/UI agencies in Europe, taking several factors into account:

‍

• Notable results: Case studies with measurable metrics (ROI, conversion rate).
• Demonstrated expertise: Specialized skills or expertise in a particular field, backed by completed projects and client testimonials.

‍

Agencies were evaluated holistically based on these criteria, drawing on options from various European countries for diversity. The list includes agencies that consistently come up in industry discussions, search results, and our own research, through August 2026. The order is not a strict ranking but highlights the different approaches through which these agencies stand out in the UX design field.

Every design choice is closely tied to a business outcome, and that's exactly what happened in the partnership between UXProject and Carrefour Romania for the development of the Act for Good loyalty app, an app with 2.9 million active users, of which 1.8 million are monthly active users.

 Clients: Aviation, public sector, nonprofit, lifestyle

‍

Best for:

• Growth-stage startups requiring scalable design systems and design foundations
• Enterprises seeking service design expertise
• Collaborative co-creation processes involving multiple stakeholders
• Organizations needing both creative innovation and systematic execution backed by global resources

‍

Designit is among the largest UX companies in the world and became part of Wipro, an Indian multinational, in 2015. Their services are organized into four areas: Innovation & Futures, Brand & Marketing, Experience & Loyalty, and Sustainability by Design. These cover business design, design research, UX/product/service design, creative technology, CX and employee experience management, as well as brand strategy.

‍

One project that caught our attention is the one they did for Sephora, through which they redefined the shopping experience, starting from the flagship store in Barcelona and extending the concept to more than 100 locations across Europe.

‍

Based on market research and needs identified among consumers, they introduced services such as express makeup bars and interactive menus, offering a more personalized experience and quick access to expert recommendations. They also expanded the skincare and wellness offering by introducing a new category: parapharmacy.

‍

The concept was developed to be easily adaptable and scalable across different store formats, including shop-in-shop, contributing to a 10% increase in sales and more than 2 million social media interactions in the first three months after launch.

4. Good Face

‍

Founded 2016, Kyiv

Clients: Fintech, esports, health, AI & ML

‍

Best for:

• Early-stage startups and scale-ups
• Companies with an existing digital product that need a redesign or additional team support
• Mid-market and larger clients, not just small startups

‍

Headquartered in Kyiv, Goodface is a digital product design and development agency, with additional offices in the UK and Tallinn.

‍

Their core services include UX/UI design, product development (web/mobile), brand identity and redesign, SaaS platforms, MVP launches, and dedicated teams for clients. The focus is on user-centered design, data-driven decisions, and a product-oriented approach.

‍

Magnetiq Bank is a European bank headquartered in Latvia, specializing in corporate banking services and FinTech solutions. Goodface Agency carried out the bank's complete rebranding, from logo and visual identity to website and digital interfaces.

‍

The project included a new design system, brand book, and brand guidelines, developed to support the new Magnetiq identity. The result was recognized with a Red Dot Award 2025 in the Brands & Communication Design category.

‍

‍

5. Colla

‍

Founded 2021, Milan

Clients: Fashion, food, architecture, interior design

‍

Best for:

• Fashion, luxury, and lifestyle brands that need premium, craft-level visual design and immersive digital experiences
• E-commerce brands prioritizing measurable conversion-rate 
• Founders who want a tight-knit boutique studio with direct access to senior designers.

‍

‍

Their offering rests on three pillars: Strategy & Vision (design thinking workshops, product development), Crafting & Design (creative product transformation), and Coding & Technology (software development).

‍

One of their most notable projects was for Valentino, on the occasion of launching an exclusive personalization service engraving initials on bag tags. Colla Studio built a digital app that connected the at-home experience with the in-boutique one. Sales advisors could send it to clients remotely to showcase the service and draw them into the store, while in the boutique they used it on an iPad to show personalization options directly at the point of sale and enable an on-the-spot purchase.

‍

The platform also included an analytics module, through which Valentino gained insights into customer preferences. The result was an architecture scalable enough to allow the rapid launch of three more seasonal versions of the service, without compromising the premium experience the brand demands.

‍

6. Lyra

‍

Founded in Madrid, 2018

Clients: Luxury retail, telecom, energy, education, media

‍

Best for:

• Public-sector and regulated organizations 
• Established brands and institutions (education, corporate, luxury)
• Clients who want one team owning both design and development end-to-end, with a formalized sprint process rather than ad-hoc delivery

‍

‍

Lyra Studio operates as a design studio that has, over time, also introduced development services for web platforms and apps. As a result, the studio brings both design and development together under one roof.

‍

On the design side, they create memorable, cross-device brand experiences, and on the technology side they develop web platforms and apps, combining off-the-shelf solutions with custom development.

‍

They stand out through their own methodology, a systematized, holistic, iterative process structured into several phases. They work in sprints with partial deliveries, so the client has visibility into the project from the very first week.

‍

One of Lyra Studio's main projects was for the Just Vélo platform, dedicated to premium bike rentals. The project involved both the company's rebranding and improvements to the online rental and payment process.

‍

Instead of selling bikes, Just Vélo offers a flexible model based on the temporary rental of high-end models, with no long-term contracts or major investment.

‍

To support this positioning, Lyra Studio created a new visual identity, inspired by the brand's punk, rebellious personality. This was carried through into the platform via a clearer, more intuitive experience, simplifying selection, rental, and online payment.

7. Phenomenon

‍

Founded 2019, Switzerland, HQ in the US

 Clients: Finance, real estate, health, mid-market clients

‍

Best for:

• Healthcare, medtech, and other regulated industries 
• Funded or fundraising startups that need investor-ready, credible product design to support a raise.
• Midmarket companies that need to scale a product team quickly (team extension) while still working directly with senior designers/developers, not junior staff

‍

‍

Phenomenon is a long-term design and product development partner for companies looking to launch, scale, or innovate. Their services are divided as follows: Launch (launching a new product), Evolve (evolving/optimizing an existing product), Rebrand, and Extend (team extension, with developers/designers embedded in the client's team).

‍

Phenomenon carried out the redesign of the Creatorland platform, dedicated to Gen Z creators building careers out of multiple forms of expression, from design and photography to writing or performance.

‍

The goal was to create a more intuitive experience suited to how today's creators work. The platform integrates AI-based portfolios, networking tools, and resources that help them connect with brands and find new collaborations.

‍

The redesign led to increased engagement and a matching process between brands and creators that is twice as fast.

‍
