KING Essentials, an Amsterdam-based fashion brand, that's originally founded by two entrepreneurs who gained a substantial experience by working for traditional fashion brands in the Netherlands. Their goal is to become the go-to brand for consistency in fits, sizes, quality, and availability. How to communicate to and with their audience segments was one of the main obstacles in the start-up phase of KING Essentials. KING Essentials didn't have much online advertising experience on board, and decided to work with Marveltest. Their decision was based on the experimental framework ideas we suggested. We've setup a complete online marketing infrastructure for KING Essentials. From the beginning we composed a strategic performance marketing fundament. Extended Data visualization dashboarding resulted in a sophisticated multichannel market approach from the start. The cooperation with KING Essentials came about to support them in speeding up the concept validation process. After 6 months of collaboration and several advice reports, KING Essentials was able to move on with a clear market approach.

KCST anticipated well on market developments during the pandemic in 2020 and 2022. The loungewear brand focussed on making life inside of the house more comfortable with their sustainable and high-quality tracksuits and tops from cashmere, organic cotton, and wool. The viability of a loungewear brand in a non-pandemic environment was one of the key research questions for KCST.  In the current e-commerce landscape, the reality is that even the best (new) fashion brands fail because of the lack of following a knowledge-based strategy. Entering the market has become easier for small brands, which results in numerous new competitors within the same niche every day. Marveltest has helped KCST to research and evaluate the playing field of loungewear extensively and provided insights for a high-performance strategy. Several step-by-step pieces of advice for continuation were written based on their customer's ongoing behavior. As a result there's now a decisive continuing  strategy recommendation.
