BIOGRAPHY

DEXX (Thai: เด็กซ์, always written in capitals) is a six member Thai boy band under DMD Music, the music arm of Domundi. The name is given as an abbreviation of Diverse Element of XX. The group was announced in June 2025 and debuted on 24 June 2025 with the single Clang Clang, produced by the singer and songwriter Hye of Paper Planes.

The members are Jamessu, Yim, Tutor, Auau, Por and TeeTee. Four of them hold profiles in this catalogue for their acting work: James Supamongkon Wongwisut, Yim Prarinyakorn Kansawa, Tutor Koraphat Lamnoi and Auau Thanaphum Sestasittikul.

Domundi manages its performers, produces its own series and releases its own music, so a DEXX member is usually working inside one company across all three.

DEXX is arranged as a six-piece led by Jamessu, with Tutor and Por on vocals, Yim and Auau anchoring the dance line and TeeTee and Jamessu handling the raps. Because every member is an actor with Domundi TV, group activity runs alongside a steady stream of series work, and the pairing of TeeTee and Por carries across both, from Your Sky in 2024 to Duang with You in 2026.

After “Clang Clang” in June 2025 the group released “อกหักเป็นเพื่อนเธอ (Beside You)” and “Skinship”, then “รักได้แล้ว (Next Status)” for the Duang with You soundtrack in 2026. Early recognition followed quickly, with rookie group honours at the Weibo Music Awards and The Viral Hits Awards in 2025.

FREQUENTLY ASKED QUESTIONS

What does DEXX stand for?

Diverse Element of XX, a concept built around the different musical genres and fashion styles the six members bring. The name is always written in capitals, and in Thai as เด็กซ์, so a lower-case rendering anywhere is a transcription rather than the group’s own styling.

Why does every member also act?

Because Domundi manages its performers, produces its own series and releases its own music, so a member is usually working inside one company across all three. All six are actors signed to the sister agency Domundi TV, and four of them hold profiles of their own in this catalogue.

How are the positions divided?

Across all six, with nobody left without a stated job. Jamessu is leader and main rapper, Tutor lead vocal, Yim lead dancer, Auau main dancer, Por main vocal and TeeTee lead rapper, which is an unusually complete allocation for a group this new.

How quickly did the group come together?

Very quickly, and in public. The project was announced in February 2025 at DMD’s Glow Up showcase, the members were revealed on 12 June, the single Clang Clang followed on 24 June, and the first showcase was held at Siam Square Block I two days after that.

Which members had been in a group before?

Two of them. Auau Thanaphum Sestasittikul and Por Suppakarn Jirachotikul had both been members of the boy group DVI, and both took part in the survival show Laz Icon before this one was assembled.

Does a screen pairing run through the line-up?

Yes. TeeTee and Por are an established acting pair, seen together in Your Sky in 2024 and Duang with You in 2026, so the same two carry a partnership across the drama slate as well as positions in the group. This site documents that working pairing and makes no claim beyond it.

What has been released so far?

Clang Clang in June 2025, written, arranged and produced by Hye of Paper Planes, then อกหักเป็นเพื่อนเธอ (Beside You) and Skinship, and รักได้แล้ว (Next Status) for the Duang with You soundtrack in 2026. Rookie honours followed at the Weibo Music Awards and The Viral Hits Awards.
