South Korean children’s content company Pinkfong, creator of the viral 90-second video 'Baby Shark', has grown into a $400 million enterprise after its stock market debut. The video, released in June 2016 under CEO Kim Min-seok’s approval, became the most viewed content on YouTube with over 16 billion views. Pinkfong’s shares rose 9% on their first trading day, raising about $52 million. Originally founded in 2010 as SmartStudy with just three employees, the company shifted focus to younger audiences, producing simple, educational content that led to Baby Shark’s global success. While the song remains a key revenue driver, accounting for about one-fourth of earnings, new franchises like Bebefinn now contribute around 40%. Analysts note that Pinkfong must prove its growth extends beyond Baby Shark. CEO Kim says the company plans to use IPO funds to expand its film and character lineup and evolve into a technology-driven content creator leveraging data insights.
