The Studio
Studio UNIKA is an independent creative studio based in Lisbon.
We help companies define or evolve what they are—then make that identity clear across everything people see, use and experience.
Our work begins before design. We listen to the story, context and ambition behind a business; we observe, question and simplify until the essential idea becomes clear.
Founded in Bali in 2015 by Grethel Signamarcheix and Sergio Castro, UNIKA is now a multidisciplinary team working across strategy, identity, image and digital experiences.
