Your Amazon account,
run like a U.S. brand.
Amazon is where most American shoppers meet a new brand for the first time. We manage your Seller Central account end to end, from listings and A+ Content to advertising and FBA, so a Korean or Japanese brand shows up like it belongs on page one.

Most U.S. buyers will judge your brand on a single product page
A proven product in Korea or Japan does not automatically translate on Amazon. American shoppers search differently, scan differently, and decide in seconds based on the title, the images, the reviews, and the price they see. A listing that reads like a translation, or an account with thin content and no reviews, gets buried no matter how good the product is. The marketplace itself has changed too. Amazon now answers shoppers through its AI assistant Rufus and ranks listings with AI-driven search that reads images, video, and natural-language questions, not just keywords.
We run Amazon as one of the channels inside a full U.S. launch, not as a side project. Our team grew up shopping on Amazon in the U.S., so we write and structure listings for the American buyer instead of translating Korean or Japanese copy word for word. One team owns the account: setup, content, ads, inventory, reviews, and account health. Your team in Korea gets reporting in Korean, and you get a U.S. storefront that holds up against the brands you are competing with.
Everything the account needs, handled by one team
Account setup and Brand Registry
We structure Seller Central correctly from the start, enroll your trademark in Brand Registry, and lock down canonical titles, bullets, and images so resellers cannot overwrite your content. Brand Registry is also what unlocks A+ Content, the Brand Store, Vine, and the better advertising formats, so we treat it as the foundation everything else sits on.
Listings written for U.S. search
Titles, bullets, descriptions, and backend search terms built around how Americans actually search, using U.S. spelling, units, and benefit language rather than a direct translation. We write for the way Amazon now reads listings, with clear use cases and natural-language phrasing that Rufus and AI search can surface, plus high-quality hero and lifestyle images and listing video.
A+ Content and Brand Store
Our in-house studio in the Los Angeles area builds A+ Content modules and a Brand Store that work like landing pages: a clear value proposition up top, benefit and use-case modules in the middle, and comparison charts that move shoppers toward the right SKU. Everything is localized for U.S. expectations and regulatory claims, not lifted from the home-market site.
Advertising across the funnel
Sponsored Products for high-intent conversion, Sponsored Brands and Brands Video for awareness and Store traffic, Sponsored Display for retargeting and competitor conquesting, and Amazon DSP once there is enough volume to justify reach off Amazon. We use Amazon's AI-assisted bidding as a co-pilot with tight targets and budgets, then review search-term reports and TACOS every week.
FBA logistics and inventory
We manage FBA shipments, restock timing, and your Inventory Performance Index so you keep storage capacity and stay in stock on top sellers without paying for overstock. That means forecasting around Prime Day and Q4, clearing aged inventory, and protecting Buy Box eligibility with stable pricing and Prime delivery.
Reviews and account health
We seed early honest reviews through Vine at launch or relaunch, automate compliant review requests, and feed negative feedback back into the listing and product. We watch the Account Health dashboard, respond to buyer messages and policy cases fast, and handle appeals and suppressions so a single violation does not put your listings at risk.
Winning on Amazon is not one big move. It is a hundred small decisions made by people who shop the way your American customer does, made every week, on every listing.
From account audit to a storefront that compounds
Audit and plan
We review your current account or set up a new one, confirm Brand Registry status, and map the category, competitors, and price band to a clear 90-day plan.
Make listings retail-ready
Before spending on ads, we rebuild titles, images, video, A+ Content, and the Brand Store so every hero ASIN converts the traffic it gets.
Drive traffic and protect Buy Box
We launch the full ad mix, seed reviews through Vine, and keep inventory, pricing, and account health in shape so the Buy Box stays yours.
Optimize and report
Weekly we cut wasted spend, expand winning keywords, and refine content, then report results and next steps to your team in Korean.
