NutriNest, founded by Le Danh Hoang, was the first company to introduce farmed bird's nest products in Vietnam. In January 2018, the company launched a sustainable product line under a new brand called the Green Bird. The Green Bird product line was positioned to meet consumers’ sustainability and health concerns, and quickly became the company’s best-selling products. To continue to grow NutriNest, Hoang was facing a crucial decision. Should he focus on the current portfolio of the Green Bird line or add new products? If he chooses to introduce new products, how should he ensure that these products will attract new segments of customers and increase sales?
