Bunker Kids

Bunker Kids is a South Korean startup that operates WHIF, an AI-powered interactive content platform. The company was founded in June 2019 by CEO Jeong Seung-wan, a serial entrepreneur who has previously exited two businesses. Initially, Bunker Kids operated in different sectors, including a personalized health-meal delivery service called Shipdan.me and an AI education service named Data Diving, before pivoting to focus entirely on the AI companion market. The company's core product, WHIF, allows users to chat with AI characters, build relationships, and create branching narratives based on their choices. This positions the service as an evolving, choice-driven narrative experience rather than a simple Q&A chatbot. WHIF has demonstrated significant user engagement, with paying users averaging 217 minutes of daily activity on the platform. The platform also enables users to create and share their own AI characters, shifting them from passive consumers to active creators. Bunker Kids has shown rapid financial growth, with monthly revenue reportedly growing 1,000-fold within a year of WHIF's launch. The company has a strong focus on international expansion, launching in markets like Japan, Taiwan, Thailand, and the United States. As of August 2026, overseas revenue accounted for approximately 40% of its total sales, with a goal to increase this to over 60%. The startup has successfully raised capital to fuel its growth. In December 2022, it secured a KRW 2 billion (approx. $1.5 million) Series A round for its previous meal delivery service. More recently, in August 2026, the company raised a significant KRW 15 billion (approx. $11 million) Series A round for its WHIF platform from investors including Kolon Investment, Kakao Ventures, and Mirae Asset Capital. The funds are intended for developing multimodal content, such as image and video generation, and for global expansion.
