Lee Sia is the mother of Green and Grim and the CEO of the eco-friendly resource circulation platform company, GreenGrim. From her childhood to the present, she has lived every moment with excitement and passion. Born and raised in Jeju as the youngest of four sisters, she grew up under the influence of her mother, who has been running a flower shop for 50 years. She has always been interested in life forms such as flowers and trees. Next to her mother's flower shop is a café run by her sister, which led her to contemplate the waste issues from the many cafés that open and close. As a result, she discovered PLA, a biodegradable plastic alternative to petroleum-based plastics, and even flew to Shanghai, China, while she was pregnant, driven by the urgency that she had to pursue this mission now or never. A week after her visit, the COVID-19 pandemic broke out, and the world began to focus on the problems of disposable products. With her foresight, GreenGrim was founded at the perfect time and has since been transforming café culture across Jeju and Korea.
