AIMERS began as a trainee group under AIMERS Entertainment, with the first two trainees, Eunjun and Seunghyun, revealed in mid-2021. In April 2022, the group’s social accounts rebranded under the name B3o1z, and the lineup expanded to six members: Seunghyun, Eunjun, Doryun, Yoel, Seunghwan, and Wooyoung. The pre-debut team released the single “Albamon Go!” as a theme song for a YouTube variety series before officially rebranding to AIMERS in November 2022.

The group made their official debut on November 17, 2022, with the mini album Stage 0. Betting Starts, led by the title track “Fight Inside.” Several members, including leader Seunghyun and main vocalist Eunjun, had prior idol experience as part of the group SPECTRUM.

The group then expanded internationally with a Japanese debut mini album, also titled Bubbling, which charted on Oricon and Billboard Japan. In 2024, AIMERS returned with the single album Somebody, contributed an OST track for Social Savvy Class 101, and released the winter special single “Confetti.” The group also appeared as contestants on the survival reality show Re:BORN.

In 2025, AIMERS continued steady activity with the single “Starry Night,” an OST contribution to the drama FIRST LOVE, and their second mini album, FULL COUNT, released in September. As of 2026, leader Seunghyun has announced military enlistment, marking a new chapter for the group’s ongoing activities.
