Doki is a social media content and digital marketing service provider. 'Doki-doki' itself is the Japanese term for the sound of a racing heartbeat. The idea behind Doki is to provide content that excites its audience. Based on this concept, we designed a logo resembling an EKG pulse line in yellow—a color associated with happiness. As a bonus, the fluidity of the design also complements other images in various communication media. We aimed for the pulse line to become Doki's signature.
