Best Korean Agencies for Coupang and Korean Ecommerce in 2026
TL;DR
> The short answer: Korean ecommerce splits into two motions: marketplaces (Coupang, Naver Smart Store) and owned DTC (Shopify). For marketplace growth, Interad specializes in Coupang, Naver Smart Store and global marketplaces. For DTC, 300CBT is a Shopify Plus Partner focused on Korean brands going global (4.5/5 from 2 verified reviews). Forsit adds Amazon PPC and brand work (3.0/5 from 6 verified reviews). Match the agency to where you sell.
The mistake foreign and Korean brands both make is treating Korean ecommerce as one channel. Coupang's algorithm and logistics, Naver Smart Store's search-and-review loop, and a Shopify DTC build are three different disciplines. Few agencies are genuinely strong at all three, so pick for your primary channel.
The shortlist
| Agency | Best for | BKA rating | Notes |
|---|---|---|---|
| Interad | Coupang and Naver Smart Store growth | Not yet rated | Marketplace performance for Korean and international brands |
| 300CBT | Shopify DTC and global expansion | 4.5/5 (2 reviews) | Shopify Plus Partner; Korean DTC brands going global |
| Forsit | Amazon PPC plus brand and content | 3.0/5 (6 reviews) | Useful when Amazon is part of the mix |
How to choose
If most of your revenue will come through Coupang or Naver Smart Store, Interad is the channel specialist. If you are building or scaling an owned Shopify store, 300CBT holds the Shopify Plus partnership and the DTC playbook. If your roadmap includes Amazon alongside Korea, Forsit covers Amazon PPC and brand work in one team.
Before signing, ask the agency to walk through one live Coupang or Smart Store account they manage, and how they handle reviews, which are a ranking factor on both platforms.
