About

Studio Unika was born in Bali in 2015, when Grethel Signamarcheix and Sergio Castro — French and Colombian, both far from home — started working together.

What began as a small collaboration became one of the island's first foreign-led design agencies. Today the studio is in Lisbon. The work is the same: brand strategy, visual identity, packaging, campaigns, and digital experiences, done with close attention and no shortcuts.

We work with companies that want to define or evolve what they are. That means listening first — to the story, the context, the ambition — before anything gets made.

From there, we build brand worlds: identity systems, packaging, 3D, websites, communication. Coherent. Considered. Built to last.
As a founder-led studio, everything that leaves this desk has been thought about. Not just designed — thought about. That's the difference we work to maintain on every project, for every client.
