Frequently asked questions

Working on these three elements usually takes between one to three, or four months and requires constant collaboration between our team and the client. The more available you are, the faster we can deliver the product to you. When it comes to qualitative and quantitative testing, additional time is needed to collect results.

We charge for the design, validation, and pitch deck based on an hourly work model. We can’t predict the number of iterations needed to create a unique product and meet your requirements. However, at the beginning of each sprint, we estimate the time required for changes. This allows you to control costs.

Yes. During the initial consultation with our expert, we’ll discuss your needs and customize the scope accordingly.

We test concepts directly with users, using quantitative methods, for example Landing Pages,  as well as participatory workshops. Before choosing a method, we evaluate which one would be best for your product.

The pitch deck presentation has a specific structure that we follow. It includes product-related content such as infographics, charts, as well as the initial product visualization. The scope is decided during our first consultation and is based on the needs that arise then.

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.”

“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.”

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.”
