ZEWLIN works with founders, creators and businesses to develop original concepts and build the intellectual property strategy behind them. Our work may include naming and brand architecture, product and service concepts, positioning, portfolio development, commercialization strategy, new categories and opportunities to extend an idea across products, platforms or markets.

We also develop, own and manage intellectual property originating within ZEWLIN, including brands, software, publications and other original properties.

We are particularly interested in subjects where the available conversation feels incomplete: experiences that are widely lived but poorly articulated, useful ideas buried under generic advice, and authors with something specific to say.

Our publishing work includes the development of original ZEWLIN properties as well as select projects from outside authors. We are building a small list deliberately rather than publishing for volume.

Alice Keane Rourke is an emerging nonfiction writer whose work explores relationships, identity, and the experiences that are often difficult to name from inside them. Her writing combines lived experience with research, with a particular interest in the distance between how a life appears from the outside and how it is actually lived.

Our involvement can begin early, with the shape of a brand or content property, or later, when an existing audience creates opportunities beyond the original platform. Depending on the project, that may include brand development, content strategy, partnerships, new formats, product concepts and other commercial extensions.

Ventures is where we develop and operate selected projects in other categories, including real estate, residential design and consumer concepts. Some are businesses in their own right; others begin as an interest, property or idea with the potential to become one.

The company operates across five main areas: intellectual property development, technology, publishing, media and creators, and ventures. ZEWLIN's portfolio includes software, applications, books and editorial properties, with additional work spanning digital products, real estate and residential design.

ZEWLIN also works selectively with founders, authors, creators and brands where our experience, capabilities and perspective can materially contribute to the project.

ZEWLIN is based in New York.
