### 2018–2019: formation, recruitment and first generation debut

On June 21, 2018, AKS Co. announced the formation of SGO48, based in Ho Chi Minh City (Saigon), Vietnam, with the joint venture between CTCP Tập đoàn Yeah1 (Yeah1 Group) (YEG) and Geo Brain Corporation, and formed the YAG Entertainment company. After the recruitment announcement on August 3 by both the AKB48 and YAG Entertainment team, audition process for the group's first generation on August 10, 2018, consisted of three separate rounds: online registration, interview, and lastly, final round. A concept for a SGO48 theater was brought up to conversation during the first livestream meeting with Japanese investors. Within the first round, candidates had to apply online on the company's website by filling out personal information, with more than 8,000 applications sent and of whom 350 candidates were selected to advance to the interview round. The candidates then performed and answered questions from the judges on the interview round, where 120 candidates were chosen to proceed to the final round.

The label then announced the 29 official members for the first generation of SGO48 on November 17, 2018, followed by their first live performance with AKB48's Team 8 a day after in Hanoi, Vietnam, as part of the "Kizuna Ekiden 2018" event.
