Björn is fascinated by the variety and diversity of design disciplines. His interests range from the theoretical analysis and development of solutions to the creative generation of ideas and drawings to atmospheric visualisations of designed 3D models. Impressive images that convey emotions and point to the future are typical of his visualisations. A deep fascination that he consistently pursues in his work. His career began with his studies at the HBK Braunschweig and the Institute of Design in Umeå/Sweden. This was followed by exciting positions at Toyota in Japan, Volkswagen, Skoda and Audi Design. For the science fiction film Ender's Game, Björn designed a vehicle for Harrison Ford and Ben Kingsley, meeting the world of film in Hollywood. The Audi A4 and RS4 models he designed are also present on the road in many variations. As an industrial designer, car exterior designer and visualisation specialist for design concepts, he recently worked on his own art book. At zweigrad, Björn focuses on intelligent design and expressive visualisations. In the team, he appreciates a personal and familiar atmosphere with a good spirit and helpful cooperation. When dealing with customers, he attaches great importance to professional communication and mutual trust in order to bring projects to a successful conclusion.

It is often those projects that, due to their complexity and scope, require an enormous amount of thought and planning that make Stefan Proud truly love his work and keep evolving further. A trained UX/UI expert, Stefan has seen a lot of the world. In 1999, he founded a web design company in London, and at a San Francisco-based start-up, which was listed on the Australian stock exchange in 2014, he was the very first employee, then project manager, and finally CTO. Stefan joined zweigrad in 2015, adding more than 20 years of experience in the areas of full service UX, UI, coding and project management to the team. “I want to push our clients to go beyond emulating past achievements of competitors and instead focus on solving current issues and responding to the future”, he says. His goal is to create flexible solutions that anticipate future technological advances and that can be easily adapted across all platforms.

Martin Reuthe loves being part of the journey from idea to finished product. His aim is to turn sketches into something usable that meets the wishes of users and suppliers, honours sustainability along the product’s entire life cycle, and combines practicality and style in a unique way. The industrial designer has been with zweigrad since 2016 and has contributed his expertise in various industrial, interface and communication design projects. Martin is your point of contact for model and mock-up constructions, storyboarding, 3D and 2D animations as well as VR solutions. To Martin, a clear and timely definition of tasks and problems is just as relevant for the success of a project as good and close communication, which starts with getting to know each other. Martin believes in exploring unknown paths and in embracing the courage to fail early on. And one thing is clear to him: “For visionary ideas to become reality you need backbone.”

Aleksandra Chodur is always fascinated by the attention given to the exceptional aesthetics of her work. She makes decisions for her compelling design solutions based on relevant data. As an expert in Data Driven UX design, Aleksandra Chodur emphasizes fact-based design. The user experience is the focus of product development, which she approaches as closely as possible through survey data and user statistics. During her management studies, she won a rectorate award for the best student. Subsequently, she also completed a study in UX Design. Since August 2022, she has been a UX/UI designer at zweigrad. Step by step she creates explicit user experiences through curiosity, clear focus on goals and good communication with all stakeholders.

Fenja Bonn sees her main task in staying on top of things while keeping a cool head. So it certainly comes in handy that Fenja is passionate about organising and enjoys the diversity that comes with being the contact person for the entire team. Fenja completed a degree course in Scandinavian Studies and English in Kiel and Reykjavik (Iceland). After graduating, she gained agency experience as a project manager with a German-Danish advertising agency. For the next five years she was then in charge of coordinating operations at a large stud farm. Since November 2022, she has been contributing her motivation, curiosity and solution-oriented mindset to zweigrad alongside the willingness to rethink processes. Fenja Bonn believes that being at work should also be fun and makes it a point to treat everyone involved with the same respect.

Playing with the CAD LEGO construction kit, making the 3D printer dance or breathing in dust while sanding: as the son of a graphic designer and a ceramicist, Robert Rödiger feels at home in both the virtual and the real workshop. Precisely because he is enthusiastic about craftsmanship, he likes tangible products that last a really long time, are made sparingly from our valuable resources and are designed to be timeless for future generations. After graduating from Mu in Kiel, Fish Island in London with many artists in the Peanut Factory and his company Unison Design & Engineering, which he ran for ten years, he joined zweigrad in October 2023. The full-but designer, who supports the entire process from the initial idea to the prototype, prefers to work collectively. He inspires cooperation through precise perception, good listening and letting people finish, politeness and appreciation as well as the ability to take criticism and a very relaxed sense of humor.

Louisa loves how UX/UI allows people to intuitively and independently learn how to use a product. The ultimate goal is for users to effortlessly participate in a prescribed process without being conscious of it, thus perceiving it as a self-guided learning experience. Louisa first came into contact with her field of expertise while studying for her bachelor's degree in industrial design. Within our team she has been contributing her expertise in icon and transition design through open dialogue with customers and colleagues.

Fulfilling, wonderful and intense - that's how Vildan Emuce Cesur describes her parental leave. After her return to zweigrad, the UX/UI designer is looking forward to the creative re-immersion in holistic design processes - from the analysis of customer and user needs to highly aesthetic design. More than ever, lifelong learning will be in focus for her: Vildan wants to deepen her design expertise, explore trends and open up to new methodologies and tools. Her goal: to use interdisciplinary understanding to create sensual user, brand and product experiences that go beyond simply displaying information and visualisations. Together with the zweigrad team, she will design even more high-quality, intuitive user interfaces that impress and inspire in the long term.

Anna Friedlmeier joined our team in March 2025. Together with her colleagues, she shares a passion for design that puts people at the centre. To create designs that offer people positive experiences, Anna combines technical UX/UI design skills with creative freedom. She is currently studying Information Design in her fourth semester at HdM Stuttgart. As an intern at zweigrad, she likes to think outside the box with playful creativity. Her goal: simple solutions that are as entertaining as they are stimulating. Anna's favourite way to find new, better ideas is through collaboration.

For Fritz Walter, there are no limits to design, whether automotive, clothing or spaceship concepts. What particularly fascinates him is the opportunity to look at everyday objects from new perspectives in order to rediscover their value. Fritz's enthusiasm for design has been with him since childhood: even then, he preferred to build his own spaceships out of Lego rather than assemble prefabricated sets according to instructions. A decisive ‘aha’ moment in his career was the Hessen Ideas Scholarship for a university project, which laid the foundation for his own start-up and Kickstarter project. Fritz, who is in his 8th semester of industrial design at Darmstadt University of Applied Sciences, has been part of zweigrad since mid-March. In addition to his creative mindset, he has a great passion for craftsmanship and analogue experimentation. Fritz feels most at home when professionalism and relaxed co-operation form a good balance.

What does Lone Schlüter love about her job? When psychology and design go hand in hand, problems are analysed and identified, thinking and working is solution-oriented and ultimately a product is designed to be intuitive and accessible. This is exactly what Lone wants to experience during her internship at zweigrad, along with as many varied projects as possible. After completing her BA at the Muthesius Academy of Fine Arts and Design, she has been studying for a Master's degree in Interface Design since October 2023. Lone is looking forward to honest and respectful interaction within the team and with customers. At zweigrad, she brings communication skills, reliability, commitment and a structured way of working.

Ellen Struck believes that interface design comes down to an interplay between people and technology. And in this interplay, it is paramount to step into the shoes of the user – who should be in the focus of each and every iterative development process. Following her degree course in graphic design, Ellen worked as an art director at an advertising agency before becoming senior art director at a tech company. With her expertise in the area of UX/UI design, Ellen has been supporting zweigrad as a freelancer since 2012. In her work, Ellen places great emphasis on creativity, user-friendliness and attractive designs – seasoned with a dash of joy, respect and variety.
