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 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).
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.
These don't require trusting us at all — they're checkable independently.
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.
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.
Some details strengthen a partnership review more than they strengthen a public web page — so they're shared directly, once we're talking.
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.
