Jeesoo

Jeesoo (지수), born Lee Jee Soo in Calgary on May 28, 2004, is the Korean-Canadian rapper in AmbiO. He sits in an interesting lane inside the team because his public image is less about loud showmanship and more about composure, diction, and the kind of grounded delivery that keeps a rookie group's stage mix from feeling overextended.

That role became clearer once AmbiO moved from member introductions into actual releases. After appearing in the group's 2025 reveal cycle, Jeesoo went through the pre-debut singles Runnin', I Wish, and Click before formally debuting with Boys Be Ambitious on March 18, 2026. At 186 cm, he immediately reads as one of the team's strongest visual anchors, but the bigger story is how his bilingual background and measured tone help AmbiO hold together its multinational identity.

For E Entertainment, Jeesoo represents the kind of member modern agencies want when they are building for regional scale instead of a single domestic narrative. He gives AmbiO a Canada-linked profile, a cleaner English-language runway, and a steadier rap presence that complements the group's younger, brighter energy.
