Jakub Kašpar

Designer that helps companies create products and innovate smarter and faster.

Over the past 10 years I’ve worked on many projects (B2C/B2B) focused on users needs in areas as print design, corporate branding, web design and product design (UI/UX).

Some of the companies were small and some of them big. The bigger ones are Flatirons, Peek & Cloppenburg, Börse Stuttgart, Strabag, Procter & Gamble, Vodafone, Merck, Kiwi.com, Antenne Bayern and IKEM.

Tria - Attendance

Tria by Jakub Kašpar

For this B2B cloud application I was responsible for the user experience of the whole attendece part of the system. Making sure it is aligned with the other parts which are human resources, payroll, tax and reporting.

My main role as the UX designer was to create prototypes which were tested and continuously improved based on the user insights.


IsletNet by Jakub Kašpar

I had the opportunity to work with David Habart, MD, PhD from Institute for Clinical and Experimental Medicine on this automated web service dedicated to the assessment of microscopic images of dithizone-stained isolated pancreatic islets.

My goal was to design an interface which will be intuitive and very easy to use. The goal was realised by intense cooperation with the key opinion users and an artificial intelligence development company Iterait.


ClaimAir by Jakub Kašpar

This web based service makes sure travellers get proper assistance as well as flight and baggage compensation when it's due.

As a part of the startup team I was responsible for branding, user experinece, user interface and also front-end development of every touchpoint (landing pages, web app, print, backoffice…).

Offered Services



Every company needs an identity to communicate with their customers. Let's work together and create brand new one or redesign the current one.



Testing a big idea for your new or ongoing project before whole development process starts will save you a lot of time, money and unhappy customers.



I will ensure that your product or service will be designed with the user centered approach, so it's intuitive, effective and delightful.

Design Sprint Process

What is Design Sprint?

It is a 4-day process for rapidly solving big challenges, creating new products, or improving existing ones. It compresses potentially months of work into a few days.

I personaly use Design Sprint 2.0. which is update of the original Google Ventures Design Sprint by AJ&smart and Jake Knapp.

Why use a Design Sprint?

It’s no longer enough to have a “good quality product”, you need to have the right product. Design Sprints are the fastest way to find out if a product is worth developing, if a feature is worth the effort, or if your value proposition is really valid.

Don’t invest months of time, invest a week.

What does a Design Sprint look like?

Design Sprint with Jakub Kašpar

The Design Sprint is essentially a 4-day intense hackathon. On Day 1 we work in person with you, my client, to define the challenges and scope of the week. Day 2 is about deciding what challenges to prototype. Day 3 is about rapidly building the high fidelity prototype, which is then tested with real users on Day 4.

What is the exact outcome?

The outcome of every Design Sprint Week is a high-fidelity interactive prototype, tested by real users, and with clear insights on where to go next.

This is not a “wireframe” or a “paper prototype”, it looks and feels like a real product.

Design Sprint with Jakub Kašpar

What happens after a Design Sprint?

Once you have a tangible representation of your product in your hand, and real user insights to guide your next steps, making decisions becomes a lot easier.

You could use a second sprint to iterate and polish the idea, bringing it very close to production-ready, or you could use the prototype to sell the idea further and develop the concept.

I have worked with Jakub on several international projects and thus far he has been the best designer bar none. He always delivered on time and each design looked completely different, unique and fitting to the theme at hand. I don’t know how he does it, but he makes every project special in its own way. I enjoy working with him and will continue doing so on my future projects.
