About Yunju Company

Who runs it

Jisung Yoon, a native Korean speaker in Gwangju who studied English Language & Literature at Chosun University. The person you write to is the person responsible for your files. On some platforms his name is spelled Jisung Yun.

Other activity

The business is registered under cross-border purchase agency (해외직구대행업), and Yunju Company also runs a purchase-agent service for Japanese buyers on LOCOKAU (Korean limited goods, K-pop items, cosmetics).

Track record

Track record so far: a fabric sourcing report, a Korean script proofread, and Korean proofreading and transcription QC on Upwork. The GEO, UGC and automation services are new, so their samples are labeled on the samples page; there are no client case studies for them yet.

How we work

• Remote and written. Briefs, questions, feedback and delivery all happen by email or platform chat. No calls or video meetings.
• Fixed price first. Scope, price, delivery date and revision rounds are agreed in writing before work starts.
• Honest by default. No promised rankings, AI recommendations or sales. Samples are labeled. If a job isn't a good fit, we say so before you pay.
