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. AI has started to bridge this gap, but it's not enough. Building successful digital products in 2025 requires more than vibe coding - it's about creating an experience that scales. But finding a builder who is able to combine AI workflows with design and development is like looking for a unicorn - until now.

Zuzze is a user-centred design and development studio run 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 across timezones. This allows her to build user experiences that empower users as well as the team along the way. See full story
