apt. was founded in 2015 by Leonie Markhorst-Kushka – a Dutch native, brand strategist, creative, and a mother – whose love for exploring cultures and new dynamics led her to live across the world and build a global network and market perspectives.

Leonie founded apt. to meet the increasing demand for seamlessly uniting performance and connection in (digital) marketing. She takes a multi-disciplinary approach to brand experience, merging hard data and deep insights with creativity, soft skills, and emotional intelligence to establish both short-term impact and sustainable long-term value growth for brands globally.
