////// QUALITY OVER QUANTITY
We intentionally cap our roster so your product gets our undivided attention.
High-quality design can’t be mass-produced. By limiting the number of partners we take on at any given time, we ensure your project never gets passed down the line or lost in the noise. You get direct access, fast turnarounds, and a dedicated team fully locked into bringing your ideas to life.
////// HOW WE WORK
Good design starts with asking the right questions.
We design to solve real friction! Before pushing a single pixel, we take the time to deeply understand your users and the challenges they face. The result is a seamless, intuitive experience that feels natural from day one and scales alongside your business.
SEE IF WE'RE A FIT
People form a first impression of your product in about 50 milliseconds. The interface immediately signals whether the product feels reliable and worth exploring.

Why teams choose to work with us
The best way to understand how our collaboration works is through the experience of the teams we have worked with:)
Matevž & Manca, Ayva Tech
Working with Studio /03 was truly excellent. The brand was thoughtfully built, from the logo to the color palette. The process was relaxed and smooth, with a strong sense for detail and aesthetics. The result is exactly what we were looking for.. and even a little more:)
They has a real feel for aesthetics and design, which she fully adapts to each brand. We would also like to highlight their understanding of the technical background of website development, which made the developer's work significantly easier. At Ayva Tech, we are extremely satisfied with the collaboration :)
Tim Cvetko, Health Performance
Studio /03 brought exactly what my collaborator and I were missing — a product and design brain. They helped us sharpen the scope of the app and design the entire user journey, from onboarding and the home screen to meal logging and training, always with an exceptional sense for what users actually need and up-to-date knowledge of best practices across the web and mobile (iOS and Android) ecosystems. Studio /03 isn’t just a team of designers — they’re the design partner that modern teams need.
Ula Tentor
I completely entrusted them with the design of my website from the very beginning, because I know they have a great sense of aesthetics & knowledge about user experience. I gave them precise details about the website's content and fully embraced the visions and ideas. That's it!
Pina Mustar, SP
I had the pleasure of working with Ziva on several projects, and I can confidently say that she is an exceptional designer and a true asset to any team.
Ziva is not only highly creative, but she also possesses a strong sense of initiative and a willingness to go above and beyond in her work. She has a natural ability to quickly grasp new concepts and tools, making her an invaluable resource in fast-paced environments. Her designs are always innovative, and she consistently delivers high-quality work that exceeds expectations.
She has proven to be a talented, creative, and self-driven professional, and we're fortunate to have her with us. :)
