TripleS (Korean: 트리플에스) is a girl group under MODHAUS. They were introduced to the public through a pre-debut project that began in May 2022, during which each member was revealed gradually. The group debuted with its first ten members on February 13, 2023, with the mini album Assemble.

On May 8, 2024, the group made their debut with all 24 members through the album ASSEMBLE24. Their goal is to become the world’s first decentralized K-pop idol group. Members rotate between group, sub-unit, and solo activities based on fan decisions. Fans participate and communicate with the group through NFT photocards called “Objects,” which allow them to vote on sub-units, content, and more.

The group’s concept revolves around the members possessing the special ability “S.” They are said to unite their powers and showcase their abilities in the “Dimension,” with each season presenting a new concept and formation.
