Hi! We’re Zima!

Our mission is to develop businesses by delivering the best (human) experience.

We focus on people’s experiences and emotions

Human beings are our top priority, regardless of whether we call them users, patients, clients, or consumers. We value relationships with our clients and within our team, knowing that this is how we create the best experiences.

We are a team of skilled experts

Our team is comprised of experts. The lead designer, with whom you will work on your project, has at least six years of experience and an impressive track record. They will work with you on your project to ensure its success.

We grow with you!

The success of every client brings us great joy, just like the achievements of our designers. We believe that together we can achieve so much more!

We know business and understand its goals

We believe that good design and a successful business go hand in hand – one cannot exist without the other. We know how to combine the two to achieve our, and our clients, goals.

In our work we prioritize


As designers, we work closely with our clients, getting to know their needs, goals, and the challenges they face. We maintain direct communication throughout the entire process, collaborating to find optimal solutions at every stage from analysis to implementation. Together, we work towards the success of the project.


Curiosity helps us better understand our clients’ problems and their users. We ask lots of questions and delve deeply into every new topic. We always aim to get to the root of the problem, finding solutions that effectively address the needs of both users and clients.


A diverse range of perspectives is an important aspect of our design work, which is why we design in duos or in larger groups. This approach allows us to complement each other’s competencies, exchange insights and ideas, ultimately arriving at the best and most fitting solutions.

Goal achievement

Our focus is on the goals our clients want to achieve. We design solutions that help them attain their objectives, whether that’s building completely new digital products or enhancing existing ones. We also assist in planning their future development to ensure alignment with their established business strategy.


We value transparency and open communication. We communicate our needs, both project-related and interpersonal, honestly and openly. We provide each other with candid feedback and keep each other informed of any issues or mistakes that arise.

“From the very beginning of working with Zima, I felt I was working with individuals who understand my needs. Zima’s team is open to feedback and willing to make changes. The created project meets my expectations. Upon finishing, I felt that something truly unique was created. However, while the results are impressive, the process is often more important, I myself feel I have learned a lot from it. I highly recommend working with Zima, especially if you value relationships, good communication and transparent cooperation.”

Mikołaj Moszyński, opinia naszych klientów.

“ZIMA allowed us to look at the client’s needs from a perspective that was previously unknown to us. They question and investigate everything to ensure that the client won’t question anything later on. Thank you.”

Emmanuel BuebVinesia

We reached out to Zima because we needed an agency to assist us in creating a product MVP. We were seeking a partner who could provide strong expertise, understand the WEB3 environment, and be flexible. Vinesia is a startup in the seed phase. In less than 3 months, we developed the UX design for the mobile and desktop versions of the – marketplace for physical NFTs. We worked with Asia, Ilona, and Marta, who helped us simplify the complex wine investor journey. They also designed clear and user-friendly communication that emphasizes Vinesia’s values.

Jędrzej Babis Vinesia opinia referencja

They speak in business language, not industry jargon, which you as a client might not understand and which makes communication within the team difficult. The UI designer, Kuba, created stunning graphic designs. In their designs, Zima remembered to maintain logical transitions between users, resulting in a consistent project.

Time For Friends IT Project Manager

We value the prompt delivery of projects and a profound understanding of IT business and its needs (technology and knowledge about our clients). They always deliver just what is needed – they chose services for us wisely, which we benefited from.

Maja poleca usługi UX UI Zimy

“Zima did an outstanding job designing a website for our hackathon and the Web3 Devs Poland community. They created an original design that perfectly matched our requirements, and they delivered it in record time, with the first version ready in just three days. I highly recommend Zima to anyone in need of top-quality website design!”

Opinie naszych klientów.

“Between January 2022 and May 2022, Zima worked on a platform for a hospital and clinic for EuroMediCare. The project was exceptionally extensive, including a holistic approach to UX and UI. All tasks were completed with due care. I highly recommend Zima as a reliable partner delivering UX and UI services.”

Michał Witkowski Ation Center

Zima UX, UI & Design Strategy delivered the project on time, thanks to their effective project management and clear understanding of the project’s goals, scope, and limitations. The hard-working, highly competent team delivered high-quality work and led a smooth, productive workflow throughout.

Michał Witkowski

Ation Center, CO-Founder

We are impressed with the results of the research conducted by Zima. The wealth of information we received has significantly expanded our understanding of both our customers and our products. Zima provided us with precise research findings and a set of valuable recommendations that have fuelled our ongoing efforts.

Our client from the Education Industry

Opinie naszych klientów

“I used to associate Zima (meaning winter in Polish) with a rather uninteresting time of year. However, the ZIMA agency has truly transformed my perception of the word. Working at the highest level may sound like a cliché, but we haven’t felt this well taken care of in a long time as an organization. Their preparations for workshops and meetings have been exemplary, and their work itself is refined down to every detail. With 20 years in the e-commerce industry, I consider their UX/UI level to be exceptionally high. That’s why it’s only natural for me to recommend them. Anyone looking to elevate their UX/UI now knows where to turn.”
