On October 29, 2017, Sia Jiwoo, then going by her real name Park Jiwoo, was a contestant on the competitive reality show, MIXNINE as a trainee representing START Entertainment. She was eventually eliminated from the competition with her final overall rank in 116th place. On April 9, 2020, she was revealed as member Sia of the upcoming girl group, Delight.
On May 11, 2021, Delight revealed that they had changed their group name to 'Just COLOR', rebranded their SNS accounts and that they have integrated themselves to be a co-ed trainee group showcasing all the agency's trainees. Thus, it is suspected that Delight's debut preparations have either been postponed or cancelled altogether. Eventually by early 2022, it seems the agency had entirely abandoned their K-pop trainee group project.
Around the same time, they created a content creator group known as 'Hello House', of which, Sia Jiwoo was introduced as a member. Since then, as a part of Hello House, she had decided to focus her career on being a full-time influencer and content creator. Sometime in 2022, she also co-signed with Soon Ent to debut as a soloist singer.
Sia Jiwoo eventually made her debut as a soloist singer on October 7, 2022, with the release of her first digital single, "Do It My Own Way (D. I. M.
O. W)". She departed from Soon Ent and Just COLOR Studio sometime in 2023 and went onto sign a contract with Starting House Entertainment.
Sia Jiwoo released her second digital single "Yummy" on June 12, 2023. Starting House Entertainment became defunct sometime in late 2024 or early 2025. Sia Jiwoo released her third digital single, "Moshi Moshi" on August 19, 2025, over two years since her last release.
In October 2025, it was announced that Sia Jiwoo has signed an exclusive contract as an influencer with Sunny Place, a brand new subsidiary under JMG.
