About Us
Amsterdam HQ, Global Team
European leadership backed by a handpicked network of specialists across multiple continents. Expert-driven execution without the agency overhead.
Work With UsYour European commerce partner
Founded in Amsterdam in 2021, The OS helps brands grow across European marketplaces — Amazon EU, Bol.com, and Shopify.
We're a small leadership team backed by specialists across the globe — marketplace experts, PPC managers, and creative professionals we've worked with for years. Small enough to move fast, strong enough to support your growth. You'll work directly with the people running your account.
Our focus is European commerce because it's where our expertise runs deepest. We understand the complexity — the localisation requirements, the compliance landscape, the platform nuances that differ market to market. We've built our team and tools specifically to navigate it.
Based in Amsterdam, we're native to Europe's most dynamic e-commerce market and connected across the continent.

Learn About Agency PartnershipsHow we work differently
No Handoffs
The people you meet are the people who do the work. No "pitch team" separate from "delivery team." No surprise introduction to junior account managers after you sign.
Direct Access
You'll have direct access to leadership. Not filtered through layers of account management. Questions get answered. Decisions get made.
Accountability
With leadership on every project, there's nowhere to hide. We're accountable for results — ours and our team's.
Efficiency
No time wasted on internal handoffs, briefing documents, or approval chains. Senior people can move faster because they don't need permission.
How we work
Results Over Activity
We measure success by outcomes, not hours worked or deliverables shipped. Revenue growth, conversion rates, ROAS — the metrics that matter to your business.
Direct Communication
We say what we mean. If something isn't working, you'll hear it from us before you notice it yourself. No sugarcoating, no hiding behind jargon.
European First
We're not a US agency with a European add-on. We're a European team with deep local expertise. Amsterdam is home, not a satellite office.
Long-Term Partnerships
We're not interested in one-off projects or quick wins that don't last. We build for sustainable growth and measure our success over years, not quarters.
Native to Europe's e-commerce capital
The Netherlands has the highest e-commerce penetration in Europe (92%). Amsterdam is home to Bol.com, Adyen, and a thriving ecosystem of brands, logistics providers, and technology companies.
Being based here isn't just convenient — it's strategic. We're positioned at the intersection of European commerce, with native understanding of the Dutch market and connections across the continent.
