AI ad production case studies — how Zeropay, Hyundai Pharm and Nemo Storage cast AI idol SweeTeez

AI advertising and video production company MYBLIN9 (CEO Derek Kim) has published case studies of campaigns that cast SweeTeez — the AI idol group it plans, produces and runs in-house — as the advertising model. Three brands from three different sectors, a public payment service, a pharmaceutical maker and a logistics service, all used the same production model: an AI ad fronted by an AI artist.

Case 1: Zeropay — official ambassadors and a storm-and-flood insurance commercial
On March 30, 2026 the Korea Easy Payment Promotion Agency appointed SweeTeez as official ambassadors for the mobile payment service Zeropay. The campaign spans promotional videos, a CM song and payment-guide videos for merchants, plus cross-border payment guides in English, Chinese and Japanese — a format that plays to an AI artist’s ease of multilingual rollout. On May 21, 2026 a TV commercial for Zeropay’s storm-and-flood insurance was released.

Case 2: Hyundai Pharm “Healthy Oligo Pop” — the face of a beverage brand
SweeTeez were cast as the model for Hyundai Pharm’s zero-sugar carbonated drink “Healthy Oligo Pop”. The members’ expressions, movement and vocals were designed around the brand’s world, and a single of the same name, “Oligo Pop”, was released as the group’s 57th digital single — a campaign that ties advertising, music and artist activity together in a way only an in-house AI IP can.

Case 3: Nemo Storage — cinema ad
For the logistics and storage service Nemo Storage, MYBLIN9 produced a cinema ad built for theatrical screens, with the resolution and image design that a big screen demands — a cinema-advertising case with an AI artist as the model.

How the work was made
Every project followed the same six steps: 1) briefing and planning, 2) script and storyboard, 3) model sign-off, 4) AI generation of visuals and voice plus music production, 5) editing, mix and mastering, 6) delivery in each medium’s spec. AI is used to generate visuals and audio, while planning, script, direction, editing, songwriting and choreography are handled by working creators. Music is completed in-house, from mixing to AI-music mastering (MasteringOne).

Besides SweeTeez, MYBLIN9 runs seven AI artists — DARK DIVA, ASHENGATE, 2HYUK, JIHO, Sakai Erika and Sophia Han — and two AI-trainee programs with 198 characters (PRODUCE 9 and AETHERIUM). The company appeared in the SBS documentary “Life of AI” in July 2026, and on October 3, 2026 SweeTeez performed on the K-POP stage of the 2026 Geochang Hanmadang Festival, which MYBLIN9 describes as the first offline stage by an AI idol.
