apt. was founded in 2015 by Leonie Markhorst-Kushka, a Dutch brand strategist and creative. With international experience and a global network, she helps fashion, lifestyle, and hospitality brands define who they are, who they’re for, and how to express that consistently – online, offline, and through integrated activations.

Now based in Berlin, Leonie works with an international roster of clients, guiding them to position effectively in Germany and beyond. She believes strong brands are built from clarity first: understanding their identity, audience, and purpose before deciding how to show up in the world.

Leonie founded apt. to support brands that want to evolve thoughtfully. She combines insight and creativity to help them make confident, aligned decisions – from defining brand direction to shaping collaborations and experiences that reflect the brand’s identity.

Specializing in strategic advisory and selectively designed activations, Leonie works with brands to refine their presence, clarify positioning, and build consistent, meaningful connections with their audiences.
