TwentyThree is an all-in-one video marketing platform that combines webinars, video hosting, and video analytics.

As part of the Design Team at TwentyThree, I contributed to the redesign of the entire Video Marketing Platform.


After establishing a new design language in the Webinars product, we were tasked with creating a unified and modern experience across all core features. I designed most of the platform views, features, and components. Sander Kuypers set the overall design direction, designed key views, and provided thoughtful feedback that helped shape the final result.


The outcome was a cohesive and scalable interface that improved usability and brought visual consistency across the entire platform.
