One honest connection, four small wins.
01 · Discover
Your story, told right.
An editorial Discover page that leads with who you are — story first, never a spec sheet.
02 · Verify
The mark you can't buy.
Earn Plug Verified — our dojang-sealed proof you're authentic and independently vetted. Earned, never paid for.
What Plug Verified means03 · Spotlight
New eyes, every week.
A spot in The Tuesday Plug, our weekly feature to a purchase-ready US audience on Instagram & TikTok.
04 · Connect
Pointed at the right buyers.
A curated directory of 40+ US retail buyers — from Sephora and Ulta to Soko Glam and H Mart — each verification-dated, with the vendor route or buyer to reach them, a fit score you can argue with, and a pitch drafted in your voice that you send yourself. Open calls are flagged when a retailer is actively seeking; we never send on your behalf, and placement is never for sale.
Discovery, verification, and the weekly spotlight are included — always. You earn the mark; it's never for sale. Paid options only amplify what you earned — never a ranking. Plans and prices are listed above.
Here's what your brand page looks like

Who qualifies
Ieum is built for emerging, founder-led brands — great products, no giant marketing budget. You don't need a huge team or a US office, just a willingness to show up honestly.
- Real K-beauty brand — Korean-founded, Korean-made, or both.
- You ship to the US (DTC, via partner, or international shipping).
- 5 minutes to fill out the application.
A connection you could buy would be worthless.
That's the whole idea. Being featured is free, every affiliate link is disclosed, and no fee ever moves a ranking. The value of our word is that it isn't for sale.
이음 — made with care, connected with honesty
Need content too?
The Plug Studio — paid content production.
A separate product from partnerships. We make short-form UGC, launch campaigns, and always-on content for K-beauty brands. Studio work is paid for the craft — never for a ranking or a verdict.
We review applications weekly. You'll hear from us within 7 days.
