About

Run by someone who's sold on Amazon too, not just resold on it.

Zeum Sirius LLC is a company. Behind it is one operator with an active, multi-year Amazon selling history of their own — which changes how a partnership review actually gets done, because the same questions have already been asked from the seller's side.

Founder

Naim Demirel

Founder and operator of Zeum Sirius LLC. Based in Germany, running a Wyoming-registered U.S. entity — a structure that puts both the EU and U.S. Amazon marketplaces within direct reach (more on that on the Brands & Partnerships page).

  • 3+ years of active, hands-on Amazon selling — not a business run at arm's length from someone who's never listed a product
  • Private-label product development, from sourcing through launch
  • PPC campaign management across live product lines
  • Supplier sourcing and vendor negotiation experience
  • Market and listing analysis using tools including Helium 10 and Keepa

How we operate on Amazon

Zeum Sirius LLC operates on Amazon through an established seller account with a 3-year track record and 1,000+ orders fulfilled per year. In the U.S., it's standard for a registered company and its marketplace storefront to carry different names — that's not a red flag on its own, and we don't expect you to take our word for it either.

We keep our storefront identity private during initial outreach, for a simple reason: publishing it publicly would expose our product mix and category positioning to direct competitors. But we verify our account age, order volume, and seller feedback directly with any brand under review — under NDA, as part of Step 2 of our partnership review process. If that verification doesn't check out, walk away. That's the deal.

Legal & Operational Identity

What you can verify without talking to us

These don't require trusting us at all — they're checkable independently.

Wyoming LLC registration

Zeum Sirius LLC is registered with the Wyoming Secretary of State. The registration number isn't published on this page to limit exposure to registration-based fraud attempts, but it's provided to any brand under review during Step 2, alongside the SOS record itself.

Corporate contact

We use a company domain email (info@zeumsirius.com), not a free webmail address, and a working phone line — small things, but they're part of the same pattern of things you can check.

Verified During Review

What's shared under NDA, not published here

Some details strengthen a partnership review more than they strengthen a public web page — so they're shared directly, once we're talking.

Fulfillment partner

Inventory fulfillment runs through an independent third-party 3PL warehousing operation in Chicago, Illinois — one we pay for, not one we own or staff. We name the partner and share verifiable details during Step 2 of the review, under NDA, alongside our other operating documentation.

For Brand Owners

Account age, order volume, and feedback screenshots are part of Step 2 of our review — no public storefront exposure required.
