Kikina was born from a shared intuition: that sound shapes how we feel, think, and connect, far more than we realise. Bianca and Jérémie, brother and sister. She tells brand stories, he composes music. Together, they decided to rethink the place of sound in physical spaces. Kikina designs neuroscience-based sonic environments for retail, wellness, healthcare and hospitality. Sound as a tool, not a decor. Each soundscape is composed on purpose, calibrated on evidence, and built to act on attention, emotion and behaviour. Arthur joined them as CTO. He designed Kikinator, the proprietary technology that powers Kikina's adaptive sonic architectures. With neuroscientists, composers and creators, the team builds experiences that move people, both emotionally and physiologically. The mission is simple: to make sound a strategic layer of design, not an afterthought. Whether in a hospital room, a flagship boutique or a brand activation, what people hear is what they remember.
