Humans are hardwired to respond to stories and visuals, and strategic communications consulting and training agency HighSpark combines both to create memorable marketing collaterals and slide decks. Co-founded by Koh Kai Xin and Eugene Cheng, the company counts Prudential, Medtronic and EY among its clients. HighSpark is launching a membership network to help professionals hone their storytelling skills through design challenges, coaching and community support.
