Who Is AmbiO?
AmbiO is a five-member multinational boy group under E Entertainment, consisting of Tetsu, Jeesoo, Ruone, Kiwon, and Seungsang. The group’s name is derived from the phrase “Boys Be Ambitious,” which serves as both their motto and their mission statement-to inspire young people to embrace challenges, find courage, and hold onto hope.
What makes AmbiO particularly distinctive is their multinational composition. With members of Taiwanese, Japanese, Korean, and Canadian backgrounds, the group brings together diverse cultures and perspectives, creating a unique synergy that appeals to a broad global audience. As member Kiwon explained, their cultural differences ultimately became a strength, allowing them to connect with a wider demographic.
The group officially debuted on March 18, 2026, with their first mini-album Boys Be Ambitious. However, their journey began months earlier with a series of pre-debut singles that built anticipation and showcased their potential. Their official greeting is: “(two, three) BOYS BE AMBITIOUS! Hello! We are AmbiO!”
Group History
Formation and Pre-Debut
AmbiO’s journey began when E Entertainment brought together five talented individuals from different corners of the world. The members, born between 2003 and 2007, came together over approximately three years prior to their debut, training and bonding as a team.

AmbiO represents an exciting new chapter in K-pop’s ongoing evolution. As a multinational group with members from Taiwan, Japan, Canada, and South Korea, they embody the increasingly global nature of the industry while maintaining a distinctly Korean pop identity. Their journey from pre-debut singles to their official debut in March 2026 has been marked by steady growth, impressive performances, and a clear artistic vision.
The group’s commitment to their message of ambition, courage, and hope resonates with young audiences worldwide. Their refreshing, energetic concept-a deliberate choice to stand apart from darker boy group concepts-has helped them carve out a unique space in the competitive K-pop landscape.
