Horizn‑Studios is known for trailblazing innovation in luggage design—having been the world’s first to integrate technology like removable power banks, launch on online design configurator, and develop future oriented material science innovations such as the Re Series, high-end suitcases made from CDs. Their smart functionalities, durable German-engineered products have been awarded by SUITCASE Magazine and GQ as top of the range in durability and style. The brand’s commitment to a sustainable future of travel makes its marketing strategies and messaging particularly media-sensitive.

This approach promises to go beyond traditional attribution, offering:

 

  • Clear visibility into which marketing channels are driving incremental engagement and purchases online.

  • Insights tailored for an omnichannel brand—especially important for a design and sustainability-minded brand like Horizn.

  • Fast setup and data-driven optimization.

 

 

“We aim to understand the true impact of our media investments—not just where clicks happen, but how different channels drive incremental sales uplifts. This pilot is a great opportunity for us to move beyond last-click attribution.” said Kimberly Koay, D2C Performance Marketing Manager at Horizn‑Studios.
