About Samuel

10 yearshands-on withAmazonand **marketplaces**.

I have built my expertise from both sides of the table, client-side and agency-side, across over 100 clients, 30 marketplaces, and very different contexts: startups getting started, SMEs diversifying, and large brands internationalizing.

What this means concretely for you: I won't be discovering anything new about your account. I recognize problems before they become costly, and I activate the right levers at the right time.

Audit & Strategy

Analysis of your current situation on Amazon or marketplaces. **Seller Central**, **Vendor Central**, 1P, 3P: I'll tell you what's holding you back, what's too expensive, and what we'll do starting tomorrow.

Effective Brand Launch

Account creation, product catalog (feed or manual), brand identity (**A+, Brand Store**). A structured launch, not improvised.

360° Advertising


**Amazon Ads**, **PPC**, **DSP**, **AMC**, **Mirakl Ads**, ManoMano Ads, Cdiscount Ads. Every campaign managed by someone who knows your catalog, not an algorithm.

Operational Management

Daily back-office, **product page SEO**, promotions, Born to Run, **FBA**. What's time-consuming for you is our daily routine.

Tracking Dashboard

Your data centralized, readable, actionable. We decide together, not blindly.

International
Expansion into European markets and beyond, with a real strategy per territory.
