Built in Canada,
for Canadian sellers.

Slabster started because listing sports cards on eBay Canada meant fighting software that was never built with eBay.ca or CAD pricing in mind. We built the tool we wanted to use.

A note from the founder

Slabster started at my kitchen table. My son sells sports cards, and watching him wrestle with third-party listing tools — none of which really understood eBay.ca, CAD pricing, or how we ship from here — got frustrating enough that I built him something better: create a Canadian listing and push it straight to eBay, without the workarounds.

It turned out to be far more useful than either of us expected. So we decided to share it with other eBay Canada sellers who'd been putting up with the same friction.

We're a small Newfoundland team, still in private beta, building this alongside the sellers who use it. If you try Slabster and something isn't right, email me — it comes straight to me.

Zillman Intelligence
Slabster is developed and operated by Zillman Intelligence, its parent company. Zillman Intelligence builds applied-AI products, and Slabster is where that work meets the sports card and collectibles market.
Atlas, our AI engine
Atlas is Zillman Intelligence's self-hosted AI engine — it powers card identification, listing generation, and vision-based scanning across Slabster's web and mobile apps, backed by a hosted fallback for reliability.
Why eBay Canada, specifically
Most listing tools treat Canada as an edge case of a US product. We built Slabster around eBay.ca policies, CAD pricing, and how Canadian sellers actually ship and price cards — not as an afterthought.
