NERON, a biotechnology company aiming to fundamentally solve health challenges based on gut microbiome research, launched a branding project. We translated complex scientific evidence into a visual language that conveys trust and innovation. Through CI/VI development, we elevated the potential of invisible “microbes” into a brand identity that anyone can intuitively grasp. We developed a design system bridging two extremes: the “precision” born from 100 billion possible combinations and the “warmth” essential for people to live healthily.
