What did our clients say about us?

We wanted to have the new website firmly in our hands
"We wanted to show that PSS is changing on the website as well. And not just through cosmetic changes or a change of website design. We wanted to have the new website firmly in our strategic hands and use it as a full-fledged and measurable sales channel. We are glad that we selected a company that helped us in this difficult task through a competitive process. We are looking forward to the new website and to continuing our cooperation with ui42."

We thank the entire ui42 team for their contribution to our project. And especially for the advice and help to keep improving. We believe that we will be able to launch the Czech market in this way as well. We look forward to the common challenge, work, and results.

If we were to create a new e-shop again, we would choose ui42 again.
Miloš Kondela
Chief Marketing Officer
From the very first moment of our collaboration, ui42 understood that mental health is not just another marketing topic, but a sensitive area that requires empathy, a professional approach, and well-timed communication.
They helped us combine quality content, AI tools, SEO optimization, and targeted communication into a functional strategy that had a real impact. The result was not just great numbers, but above all, that we were able to open an important social topic authentically, sincerely, and humanely.
Thanks to this collaboration, more than 10,000 people found the right professional help. We thank ui42 for the partnership and are pleased that our collaboration continues further.
Magdaléna Kajan
CMO & Co-Founder at ksebe
We are extremely satisfied with our cooperation with ui42. They fulfill the plans we have set and even exceed them at a lower overall marketing cost than we planned. They are professionals who know what they are doing and perform their work with quality.
David Gavaľa
Director of CK DAKA
Very clear and professional communication, thanks to which we were able to quickly get the PNO to the desired level with ui42. We clicked with ui42 from the beginning, understood what we wanted, and proposed a way to get there.

Chatbot by ui42
Overall, we perceive the implementation of the chatbot positively. Objectively and subjectively, we feel a decrease in phone calls and emails to our customer service department. The chatbot helps us during weekends and holidays. Before introducing the chatbot, we always dealt with a "pile" of emails on Monday after the weekend, and there really were a lot, that has improved. The volume of inquiries is manageable. We were able to shift free capacity from the customer center to other tasks and projects, which I consider a benefit.

Where our ideas take shape in the digital realm
When looking for a supplier for our website, we were searching for an agency that would work with us to create a cohesive team and wouldn't approach the collaboration in the typical agency-client manner. We needed the agency side to also understand our business, vision, and mission so that they could contribute equally to the development of the Voxberg website. At ui42, we met these expectations fully, as today, proposals and project briefs for further development no longer come solely from our side but also from ui42, which we highly appreciate.

Journey mapping and UX testing for Generali
For a while, we internally addressed the low conversion rate of our mandatory contract insurance calculator. Together with our UI team, we embarked on usability testing, successfully pinpointing numerous UX issues and deficiencies that were hindering users while filling out the calculator but had remained unidentified by us previously. Simultaneously, we received concrete suggestions for adjustments and improvements that significantly helped us increase the conversion rate of the calculator and elevate its quality to a new level.

Sizzling brand and Website that'll make jaws drop
We were looking for a partner in the Slovak market who would help us become more visible in the Slovak and Czech markets, get closer to potential clients, expand our presence, and also help us build our company's visual identity. After several discussions with other agencies, we chose ui42, and we are currently very satisfied with our cooperation. We are currently recommending ui42 to our clients who are expanding into Romania.

A user-friendly portal for a crowdfunding platform
We greatly appreciate the complexity of our collaboration, which ensured that the proposals were not developed "from the desk," but based on real data. These data revealed discrepancies between our assumptions and reality, helped determine priorities, and, not least, minimize the risk of project goal non-achievement. We also highly value the cooperation from a human perspective – working with your team was a pleasure.
"We have excellent experience with the company ui42, the cooperation with them is always professional and efficient. A big thank you goes to the project manager Rastislav Sásik, whose leadership and organizational skills have significantly contributed to the success of our projects. His attention to detail and ability to solve problems constantly convince me that we have chosen the right partner. Of course, I realize that this success is due to the entire ui42 team, which does a great job.
Thank you and I look forward to more successfully completed projects."
Lukáš Adámek

They handled the migration to the new website excellently
"We would like to thank our colleagues from ui42 for their excellent handling of the migration to the new Feedo website, and that's not just from the perspective of technical SEO. Lazy load, next gen image loading, deleting old code, and the excellent handling of URL migration, are just a few of the things that are mainly reflected in the improvement of conversion rates, and thanks to which we have been hearing positive feedback from our colleagues and customers since the launch of the new website."
Patrik Beťák
Marketing Manager
We have successfully built a top-notch e-shop and e-commerce project
"We have been working with ui42 since 2018. During this time, we have managed to build a top-notch e-shop and e-commerce project Najšport. As soon as they took over marketing, all key factors - traffic and turnover - improved significantly. The colleagues from ui42 are always willing to meet our requirements and we can agree on the ideal solution for our company."
Patrik Kedzuch
Owner
The testing did exactly what we expected
"Thanks to usability testing, we were able to see the real behavior of our customers live when using our Business24 service. We confirmed or disproved some of our assumptions about how real users actually understand our service. The testing met exactly what we expected. We gained valuable insights on how to design our service so that it is as intuitive as possible and best meets the needs of our customers. Thank you ui42 for the excellent cooperation."

Proactivity, independence, and professionalism
"The work on UX with ui42 exceeded our expectations. Proactivity, independence, and professionalism were part of the entire collaboration, so I highly recommend working with the Dušan Vereš team for NORTHFINDER."
Matej Karaba
Brand Manager
At ui42, they can swiftly react to ever changing needs of customers
"Only a few external partners can fully keep up with the rapid growth that Dedoles has faced since the beginning of last year. Fortunately, ui42 is one of those who can handle this pace and can adapt to often rapidly changing needs. Thanks to this collaboration, the website, which is a key source of turnover, is the most stable element in our IT area."
Ján Sárkozi
IT Manager
We encountered high professionalism
"In our collaboration with ui42, there was maximum satisfaction in our team. We met with high professionalism, the willingness to consult every detail, and a very proactive approach. We also want to highlight the excellent work on the actual web development, the trouble-free e-shop, and the interesting design. Satisfaction is also reflected in our customers, who consider our website to be simple and clear, which is paramount for us."
Renáta Téglássy
Co-founder
Trouble-free operation is granted
"Our long-term collaboration gained momentum in 2014 when we decided to solve the sale and distribution of our books exclusively through our own website in Slovakia. From our side, the request was to redesign the visuals and to implement B2C and B2B orders in real time - in online connection with our warehouse system. Gradually, we have gradually reached where we are today, and we take trouble-free operation for granted."
Juraj Heger
Director
Services of ui42 and its employees are at a very high professional level
"When choosing a UX/UI service provider, we conducted a competitive process. We selected the ui42 company from several companies for their comprehensive offer, the possibility of additional services, and quality references from their long professional work in the field. During my more than 20 years of work in the online business, I can safely say that the services of the ui42 company and its employees are at a very high professional level, even on a global scale."
Adrian Brázdil
Senior Digital Marketing Manager
Right then and there we knew we wanted this partner
"I remember when I called ui42 for the first time and Aďo (Andrej Kajan, CEO of ui42) said: "Guys, we won't just build you an e-shop, we're becoming your business partners." And right then and there we knew we wanted this partner."
Janči Gonda
Co-founder
Promptly respond to our ideas and requirements and then implement them on the web
"As our company ags 92, s.r.o. expanded, we needed to find a web agency that could promptly respond to our ideas and requirements and then implement them on the web. Thanks to our collaboration with ui42 and their flexible CMS Buxus content management system, we were able to launch a responsive website, followed by a personalized loyalty program called Spokojná mamička (Happy Mom) and B2B websites for the company's Slovak and Czech wholesale departments."
Adriana Guttmannová
E-Commerce Manager
Always professional and client-oriented
"Holokolo was created in response to the successful business development and the demand for diversity. Therefore, we were looking for a partner who could cover several e-shops under one roof and one back-end, which we successfully achieved with ui42. We are taking advantage of all the advantages of synergy by having one platform, while ui42 does not forget about the individual solutions that both e-shops require, always professionally and client-oriented."
Andrea Podstrelencová
Owner
We found everything we were looking for under one roof at ui42
"As our company grew to an international scale, we were looking for new technological solutions that would meet our complex requirements and then be able to help us with the daily development of our business through PPC and Facebook campaigns. In ui42, we found everything under one roof. We always encounter a proactive approach and a willingness to help the client with individual requirements even beyond the scope of the assignment."
