Where Technology meets Design

One of the main challenges software teams face is bridging the gap between design and development. Designers lack technical knowledge, while developers struggle with creating engaging and user-friendly interfaces. Building successful digital products in 2025 requires more than just selecting colors or writing clean code - it's about creating an experience. But finding a builder who is able to combine design and development into innovative experiences is like looking for a unicorn - until now.

Zuzze is a user-centred design and development studio created by Susanna Nevalainen, a Frontend Engineer and Human-Computer Interaction (HCI) Designer. Over the past decade, Susanna has built engaging experiences from 0-1 in the Silicon Valley and Europe. With the help of a holistic product development approach, she empathizes with the needs of the business, users, designers, and developers. This allows her to build user experiences that empower users as well as the team along the way. See full story
